Hello hav ,

 

 

 

I extend my gratitude to you for contacting us about this issue through the forums and please, accept my sincere apologies for any inconvenience that you have experienced.

 

 

 

 

 

I would like to know if the modem's power light would really turn off and then turn on by itself. If it does, then this would be a hardware issue.

 

 

 

Sporadic or intermittent loss of your connection to the Internet is often caused by electronic or physical interference. If your Internet connection is coming and going, you may want to check the following

things:

 

 

 

    - Cordless phones and other electronic devices are the most common causes of intermittent internet connectivity issues. Cordless phone systems running at 2.4 GHz often run at the same frequency as your DSL modem or home networking router. If you are experiencing intermittent connectivity issues, you may need to replace your cordless phone with one that runs at a different frequency.

 

    - Large metal objects and electrical equipment such as televisions, home entertainment electronics, and microwaves can also cause interference. Try to keep your DSL modem and wireless home networking router away from these sources of electronic interference. Check with your neighbor. You may both be running wireless networks at the same frequency. The solution may be as easy as changing the channel of your wireless router.

 

    - Physical obstructions such as walls, floors, home entertainment electronics, appliances and furniture, bodies of water (aquarium) can cause interference if the wireless signals have to pass through them.

Move your DSL modem or wireless home networking router to another location so it isn't in the line-of-sight of these potential interference factors.

 

     - Your phone jack may be defective or damaged. Try connecting the modem to a different phone jack, if possible. If the hiss and background noise is gone, the initial phone jack is defective and should be replaced.

 

    - The RJ-11 phone cord that connects your modem to the phone jack may be damaged and need replacing. If your phone cord is over 14 feet long, the signal may be weakened sufficiently that it is intermittently lost.

 

     - DSL filters are needed on all phone devices except the DSL modem.

If you have more than one phone line entering your home, DSL filters should also be installed on the second line, even if it is not connected to your DSL equipment.

     - Phone ringing disconnects DSL service if your DSL service is disconnecting when your phone rings, you probably have a phone somewhere in the house/office that doesn't have a DSL filter installed between the phone and the wall jack.

 

      - The inside phone wiring in your home may also cause intermittent loss of the DSL signal. Shorts, grounds, poor line quality, etc. can degrade the DSL signal.

 

 

 

This issue would be best resolved by calling us over the phone so we can do a line test and diagnose what the problem really is.

I have this exact same problem. Its driving me insane to the point where I'm looking at different services because I've called their support and I always get the same answers. They always assure me that the problem will be resolved then when I hang up the phone the problem continues.

 

I've even had two people come over to my house so they can see the problem and nothing ever got resolved. One of them even suggested that I was making it up.  :smileymad:

 

Totally frustrating so I know how you feel. I'm not even going to bother calling AT&T anymore because I doubt the 101th time is going to fix anything. If somehow they managed to fix the problem for you please let me know how! If not then I'm going to cancel my service immediately.

My wifi portion of the RG works fine for several days or weeks but eventually starts dropping all wifi connections becoming intermittent. The ONLY thing that fixes the problem for me is to unplug the RG power and allowing the RG to power back on. This fixes the problem but eventually the problem comes back and I have to do the power reset to fix it once again. When the problem is happening, the ethernet connections to the RG work fine. It is ONLY the wifi that is affected. I have not found a permanent solution yet. I am on a channel that is NOT being used by other wifi but it is possible that other wifi are switching to my channel at times but that does not seem to be the problem since turning off the power always fixes the problem for a long time. But it ALWAYS returns every few days or weeks and it needs to be fixed once and for all. Any ideas?

thanks,

Robert B.

Do you have Uverse?  You mentioned RG (which is what we call the modem/router).

I have also been experiencing my AT7T 2 wire modem dropping internet connection. It doesn't reset actually. But it seems when I am streaming video to a wireless device, like my Roku, the 'internet' light will go out, and the 'DSL' light starts blinking rapidly. after say 20 or 30 seconds, it corrects itself, and its fine, until it happens again. Now it seems that the DSL signal, or frequency somehow cuts out from the phone line to the modem, because those 2 lights that go out have nothing to do with the wireless section of the modem. I dont know. Had the same problem with an older model of the modem as well. Any other thoughts anyone?

Hello All and Tech support,

 

Evidently this "cutting out" of the 2 wire 2701HG-B router is a plague, because I am finding messages all over the internet, with people looking for a solution.

 

I have to say that this "cutting out" of DSL signal has become so bad in the last several months that I am probably going to have to consider another carrier.  My husband and I cannot deal with sporadic internet to this extent.  This is not just us and not just our router/modem.  My mother lives on the next block, has ATT DSL and -- now -- a "brand new" 2 wire.  She bought a new one, obviously having been told by someone that her cutting out problem was probably due to a broken 2 wire.  Well, she has the new one and the problem persists at her house a block away, just as it persists at my house -- with a 1.75 year old router.

 

In desperation, I am having to unplug the router, hoping that works for a fix, but I think something else is going on with so many of us complaining.  This has only begun occurring in the last 3 months or so, so what can it be?

 

I am not about to spend money as my mom did only to end up with the problem still existing so...  What might the solution be?  I have had my portable phone a foot or so away from the router, I will move it.  The router sits within an inch of my HP Laser jet CM1312NFI.  My Samsung desk top monitor (23 inch) is situated about a foot and a half away.  I also have a splitter plugged into the DSL noise thingie, one for the modem, one for the phone line.  All of the latter has been the case for the 1.75 years that I have had this modem/router, and there were not problems until "both" my mom and I began experiencing them several months back.  There is a difference in that I have only had my Acer laptop since April, however the problem did not occur within the first several months and the laptop sits within inches of the router.

 

Now then, am I to believe that I have to move this router away from everything in order for it to work, when it was working?

 

Can I suggest there is something going on with ATT's DSL signals?  Could that be?

 

Can we all get some help with this?

 

Thanks

 

Tink

 

I did notice in another forum that people had noticed their problems with their lap tops, evidently their desktops were not experiencing the problem.  They also notice the problem with wireless, I am connected by Ethernet and the problem persists (I disabled the wireless) -- BUT I am also on a laptop.  I do not know whether my mom is on her laptop or desktop when she has the problems, I'll have to ask.

 

Here is another thread on this subject:

2wires are kind of funny devices... 

 

A few things that have helped with people with 2wire wireless problems causing the modem to reboot with no rhyme or reason

 

  • Ensure you are either using WPA or WPA2- Apparently some wireless devices have a hard time on the wpa/wpa2 auto mode transition. This can be cleared by forcing either WPA or WPA2 not both or Auto. YOu can see if this is your problem by checking the 2wire's logs and looking for "err_dma" if it is present in your 2wire logs when the modem reboots, then you need to go in and change this. 
  • Change the base ip address- Yep, change the base IP address to 172.16.0.1 or something besides the 192.168.xxx.xxx range. I can attest I have solved a fair share of wireless and wired internet connectivity problems just doing this. 
  • Check and make sure the wireless channel you are in not flooded with devices. I had one guy that was getting the disconnects everyone is describing. Come to find out there was about 50 access points all on channel 6 as well as him. He switched to a different channel and the problem went away as the other channel was much more quiet and not as "noisy or crowded." 
  • Make sure your wireless laptop or device has it's most current updates. As manufacturers learn of wireless network card problems and such they may have released driver updates to alleviate your network card issue. Be sure to investigate it. Another website called driveragent.com can determine if you have a good or bad/outdated driver. I use driveragent.com to solve driver problems with equipment all the time. It's a quite nice resource to have on hand!
  • Is your wireless card/device transmitting at full power?- If not you may need to check this. Some laptops cut the power when you go to battery mode, or put the wireless NIC asleep when you go off constant power. This may have to be adjusted if the Wireless Network card doesn't "wake up" very well. I had a dlink pcmcia card that was this way. 
  • Is your base station at full power?-  Again same as your laptop/wireless device, make sure the base is also transmitting at full power.  
  • Do you need a range extender/another access point?- I have an older home, so my walls are a lot thicker. I found that my wireless while it's located on one side of the house the back yard wasn't getting hardly any coverage. A long cat5e and a access point on top of my Fridge toward the back yard alleviated the coverage gap quite a bit.  Wireless G access points you can find on ebay for relatively cheap. I bought mine for $20 including shipping!
  • I have a mac.....  If you have a mac you may need the following link to bring your wireless under control- follow this short link to another att.com forum thread....changes to 2wire for mac to work  I am not sure why the Mac would care but apparently it did. I had someone at the genius bar ask them as well, and it seems that I may never get an answer to this one.

We too are dealing with (going on almost 2 months now) this problem of the 2wire dsl box shutting off over and over again.  I am so frustrated at this point, I dont know what to do.  I have contacted ATT so many times, and each time you have to COMPLETELY start over with each person that answers the phone.  Half the time I get people who have accents so thick that you cant understand them, which isnt a great customer service point when you are dealing with customers who have technical issues. 

All of our problems started when we heard that we didnt need a phone line to have DSL.  So my husband contacted ATT to ask if this was true and they said we didnt,  so we cancelled our home phone line.  IMMEDIATELY we had no internet and intermittant periods where we could get on for maybe 3-5 minutes at a time before it shut off, and the finally no internet.  We called they sent out a tech to put a new box on or something, and we were able to get on, but the modem keeps shutting off. 

I began calling ATT to get to the bottom of the problem, and I asked if dropping the phone line was the problem, to which they assured me it was just a coincedence that it started happening then.....Im still not convinced its not that!

The most annoying thing is that EVERY person I talked to from regular tech support to advanced tech support ran line tests and told me there was a problem with our line.....so they scheduled out a tech who never actually came to our house but called me on my cell and said he fixed it from the box down the road and that a relay was tripped and to call him back directly if it went out again.  It worked perfectly for about 2 hours, with full internet, and then out again.  I called him and he told me that ATT was having an issue that they had no answer for, and that several people in our area were having this issue and that they were going to have a big conference call with all the techs and try to come to some answer...he alluded that he thought it might be an update that had gotten sent down that the dsl boxes werent compatible with.  That was 4  weeks ago, and nothing has changed.  I called in again and voiced my displeasure about the tech not even having showed up here, and no call back or anything to see if our problem was fixed and received a whopping 19.00 credit for my trauma......I have a notebook full of notes, and tech names and outtages a months worth, and still no answer.

 

One clue that seems important but nobody has addressed, is that my sons can be on the computer all day (local only no full internet, but on all day with no shutdowns) and the minute I come home and even open my wireless laptop, it shuts the dsl box off.  It resets itself after a few minutes, but it seems it revolves around my laptop and the wireless network.

The 2 wire is in the room where my wireless laptop is, as well as 1 of our desktops.  My sons use a router in there part of the house.   Most of the time, my wireless taps into my sons router, and only sometimes will it be running off the dsl modem. 


If anyone has any idea's, please let me know.......If its the phone line, I will hook that back up. 

We cannot stream movies or downloads or use our netflicks successfully due to the constant shutting off of the modem and internet.  It would be nice to have full internet again.

I have a Dell laptop running windows vista business....same laptop I have had before the phone line was turned off.  We  have a router in my sons part of the house, with an ethernet cord ran from thier end to the 2wire dsl modem. 

I have had my modem checked at the att store and they said it was fine and working properly.

After we had the phone line turned off, and the tech came out and installed some new box or something, my son had to re register my laptop.  Do you think this is a problem connected to my laptop?

 

And by the way, thank you for any help you provide!

based on what you are describing, I would say yes. 

 

what you might try is this. 

 

try a wired connection to your laptop and turn off your wireless. This should give you a clue if the problem is in the wireless, or the operating system. 

 

Least then if you get it narrowed down that far, you will know for sure. 

 

Another way to confirm would be to go to like wal-mart/best buy/local computer store and buy a USB wireless NIC and test/confirm. All you would need is say a 802.11b/g nic to confirm. 

 

If the one you have stays up and running and doesn't crash the 2wire, via wireless- then you will have nailed it down to the wireless built into the laptop.

We too are having the same problems many of these other people are having with our 2wire gateway. Our problem started late saturday night, early sunday morning (october 29th into 30th 2011) while watching Stargate Universe on Netflix, in the day or so since the problem has excalated to happening ANY time ANY wi-fi connection initiated.

 

When I turn on my Xbox 360, the wireless connection connecting to it immediately crashes the modem (I've stood in the room with the modem, turning on the console from across the house, watching the modem die as soon as the 360 turns on).

 

When either myself or my roommate turns on either of our 3DS' the wi-fi connection crashes the modem (same as the with 360, I've stood in front of the modem and watched it happen as soon as the connection starts).

 

If the the devices, or the wi-fi connection coming out of them, isn't turned off the gateway will continuously cycle as if it can't find any internet or DSL signal, or any of the connections to the computers we have wired to the modem by way of Cat-5, only the Wi-fi light stays on. The night this began, before we figured out it was the wi-fi causing this crash, I stayed on the xbox playing offline (but with wi-fi still being on within the console) for at least 4 hours before I turned the 360 off for the night, and only then did the modem properly cycle and the internet was restored. When the Wi-fi connection IS severed the modem cycles and restarts as if the the power went out, or I forced a reset.

 

The modem is absolutely fine when the wired computers use it, this only happens when a wi-fi connection is made.

 

Seeing as this is happening to a few of us, across the course of a months time, I'm not sure if we can really call this an isolated incident.

 

Also, we do not have U-Verse, it isn't even offered in our area (despite living in a fairly major city) we have the 3mbps Legacy DSL plan, which is the highest plan we can get in this area.

I wanted to add to my above post that I just got off the phone with a service rep (after being directed to call from the online chat rep) and was told by the rep (whose name was Michael) that "there was nothing he could do" but could charge us $100 to replace the modem.

 

After inquiring as to why I should have to pay a $100 charge for the modem very suddenly not working with our wi-fi connections he said "because it isn't on warrenty any more". I then I inquired about why I was given this modem at no charge by a technition who had come to my house at least 2 years ago to fix a completely seperate issue that reoccures (and still reoccures, even after the tech gave us the new "more powerful" modem, so we could -in his words- "even bother to get enough of a singal to even use the service at all") in the spring time, yearly. The customer service rep informed me it was free because it was included in my service, where I reminded him that, no, the first modem I was given that Tech said was far too weak, was included with our service, not this modem. 

 

All the rep could answer is "I understand" and told me I'd still need to pay $100 for a replacement. Considering I've been a reliant customer for years now, and can't use the service AT ALL without a modem, I still fail to see why it isn't as included outragous price I'm paying for such a low speed service, in my area.

 

I then inquired if he had access to the forums to see this thread, and I was told "no we don't have any access to that information". I then informed him that this thread had many people with the same, or similar issue, and it couldn't possibly be a coincidence that this suddenly happens to so many people in a months time. He said "I understand" (Again) and said "but I don't have access to that information, so I can't help you there".

 

He then went so far to inform me that I haven't had an issue since 2009 (when the tech gave me this modem, and told me what I've already repeated here twice), in which I had to inform him rather bluntly that I have had many issues since 2009, but I've weathered absolutely every one of them without calling because I'd get the same exact "I can't help you" response he's given. Sending techs out to my house has obviously not fixed any issues, and AT&T isn't willing to dig any deeper into a --begrudgenly-- loyal paying customers problem past a certain point -so why bother calling any more. I went on to tell him that the only reason I bothered calling at all tonight was because this is a COMPLETELY new issue for us in this household, where as the other issues we have (constant, random, crap speeds and disconnects) are ALWAYS in the spring for some reason, though after 5 years they've never once been able to isolate any of the problems and do any thing about them.


So yeah. I'm pretty close to being done with AT&T's service completely, and will be spending tomorrow looking into my options, if I get no where tomorrow night both calling the AT&T sales department and being called by Tier 2 support (if they even call. I've been stiffed by AT&T support who say they'll call back the next day at least 4 times before) I'm 99.9% sure I'll be leaving this company.

When the wireless fails does the log show any errors like "err_dma" ?

Where is the log your talking about? The only thing that resembles a log is the broadband link statistics page with its list of accumulated errors over a period of 24 hours. (but its not a text list, its more like headcount of the errors ect. -none of which look like the one your asking about)

I just reproduced the same crash that I've been able to almost (more on that in a moment) consistently reproduce in the same way for days now and nothing like err_dma shows, probably because I don't even know where I'm supposed to be looking for it. However, the crash completely reset the broadband link statistics page, so any insight that might have from over the last 17+ hours is now gone.

Also want to mention again that when the wireless fails, the whole modem goes dead, then comes back up with ONLY the wireless light on. I have zero access to the modem during that time. Just a few moments ago when I reproduced the crash to see if I can find what you were talking about, I had to -like I've also mentioned before- go on and shut down the xbox before the modem would even cycle correctly and allow me back into the modems interface.

Reason I said "almost" in 2 paragraphs ago is because last night, after I posted that last bit above about my time on the phone with the rep, I went into the living room and turned on the xbox to at least play something offline and unwind a little, and the connection --for whatever miraculous reason-- stayed connected and didn't fall flat on its face. So between 10pm to 1am I couldn't do anything but crash, while From 1am to 5:30am, the modem didn't crash and I get disconnected from Xbox Live due to a low signal (or any other reason I could be d/c'd).

 

I also just got finished running another test where I turned off every internet using item in the house (xbox, all 3DS', DS' and computers) and then turned on ONLY my 3DS. While it was connected to the modem alone, the modem didn't crash. When I turned on my roommates 3DS, in addition to mine still being on, the modem crashed immediately. Apparently, whatever is causing the crash can't handle the draw from multiple wi-fi devices, nor can it handle the draw from a single wi-fi device when a wired computer is also running (like the first reproduction I did tonight).

 

This seems pretty congruent with most stuff I found today while digging into this. While looking around for answers I found a treasure trove of information in the exact last place I'd ever think to look for it: The bestbuy.com customer reviews for this exact same gateway modem -an item Best Buy sells over their website. I want to say a good 90% of the reviews all recount pretty much the same issue myself and -at least- Cakewzd have brought the the attention of this forum: Went to go connect to our favorite wi-fi devices and had the modem crash, rinse and repeat. And some went as far as to say they did what I did:  called AT&T, were told they couldn't be helped and were pressured into immediately spending $100 to replace this proprietary modem before ever exploring other avenues.

 

Many of them claim the problem is the modem's powersupply, that the supply just fails. Most of those same people say that there's a replacement cord (or something of the sort) that they were only able to find through AT&T (go figure) that helped the issue. Some even said they had to go so far as to get the cord and replace a resistor within the modem -and even that seems to be only a temporary fix.

 

Some of the people reviewing the modem had actually gone through multiple replacements before altogether giving up on AT&T and its shoddy hardware. Some having to pay in full for new modems even though they were still under warranty -as AT&T wouldn't honor it, and one guy telling a story where HE had to pay out of pocket for the technician to come to his house to check out the situation before anyone ever figured out it was the modem's powersupply. And the consensus from most of the people who have seen these issues with the modem is that  AT&T knows these gateways are sub-par and can't handle much more then a year of use, gave it its warranty according to that, and that the reps know this, yet don't tell the customers the problem -stringing them along till they feel like they have no choice but to spend $100 on the replacement.

 

So, I'm still completely willing to work with you on figuring this out, but I've become pretty positive that its the modem's powersupply and not something within the setting, or suddenly something having to do with the devices trying to connect to it.

 

 

I'd love to hear otherwise, however. So lets please continue troubleshooting for the time being.

Here you go. Some more stuff to try. 

 

 

Try this one or confirm if this is on the DSL diagnostics page first... you will want to have the 2wire's interface (dsl diagnostics up when you turn on your friends DS) if this is what's causing it, you should see it briefly before the 2wire dies. You could also just go in and change it to WPA or WPA2 and power his DS on and if it stays up, then you may have nailed the problem down at that point. 

 

Err_DMA  fix:

As far as err_dma, from reference I got it had something to do with on the dsl diagnostics page.  Under the "Exit code" 

 

http://www.dslreports.com/r0/download/1675143~63d3160610e6da5c0978788df8371698/080411.png

 

What seemed to fix it was the following... 

 

Point  is do not use dual WPA/WPA2 authentication mode (also known on the 2wire as "WPA-PSK and WPA2-PSK") on 2WIRE 2701HG-B. Leave it at WPA2 or WPA, or (God-forbid) WEP, only. 

 

 

 

This one could help as well, maybe you are interfering or the modem is interfering with another more powerful wireless signal. Now if there is no one nearby or you are out in the middle of nowhere, this can be probably the least of the solutions to try. This one typically would be more popular if you are in a city setting or in an apartment complex. 

 

Try a different wireless channel-

I had one guy that was having this similar problem and he had 35 devices  all on channel 6. He changed to a different channel and that seemed to alleviate his issue with the 2wire.

 

This is what he used to find a "Quiet" channel, and told the 2wire to go to that channel. There is only 13 channels in the united states.I think he found no one in his immediate area on "channel 9" so he took that one. Said his wireless cleared right up. 

http://www.metageek.net/products/inssider/

 

or 

 

 

 

This one might be a good idea none the less based on just the sheer number of devices talking on 192.168.x.x these days. I would do this one just to simply and solve some wired and or wireless network problems. You might be quite surprised how well this one works. If you have any devices arping your 2wire to death, via wireless, this might come to an end. 

 

Changing the base IP address: 

I solved another one just by changing the base IP address from 192.168.x.x to 172.16.x.x.  This one seems to solve quite a bit of wired and or wireless problems. Since about 99.9999% of devices made today talk on 192.168.x.x flavors there might be confusion as to which local network to listen to. THis change would alleviate this problem. As more win7 and macs remember what IP address they had under their connection settings, this can resolve those problems. 

 

To change the 2wire IP address range follow these instructions below


  1. While connected to your wireless network, go to http://gateway.2wire.net/ or http://192.168.1.254, http://192.168.1.1, or http://172.16.0.1 .  You’ll have to enter a password or two.
  2. The 2wire main page should come up
  3. Go to the “Home Network” tab, click “advanced settings
  4. Go to “private network”
  5. Click 172.16.0.0
  6. Click Save
  7. Reboot the 2wire and any desktops, laptops, phones, game consoles, etc. as these devices just became disconnected and will have to be issued new addresses as they come online from the 2wire. 

 

 

This one may alleviate some issues with game consoles, and macintosh systems. 

 

 

Disabling Packet flood and enabling strict udp session control.

 

Note: this may also resolve some connectivity issues with Macs that may have a problem keeping a connection. This may resolve some gaming console issues.

 

  1. While connected to your wireless network, go to http://gateway.2wire.net/ or http://192.168.1.254, http://192.168.1.1, or http://172.16.0.1 .  You’ll have to enter a password or two.
  2. Go to “Firewall” and select “advanced Settings”
  3. Check the following checkboxes/radio button dials
    1. “Strict UDP session control (check if unchecked)
    2. Uncheck “Packet Flood (SYN/UDP/ICMP/Other)”
  4. Click “Save”
  5. Reboot the 2wire unit and reconnect

 

 

 

Truthfully if it is a power supply problem, it should  be present whether wired or wireless. Not just wireless and not when you turn on a specific device. Otherwise the first device you turned on via wireless should have failed too.

I am having this same problem which began late last week AFTER having residntial phone service reestablished back at my house. We have had only DSL for over a year and no problems. When I had a local phone line reconnected last week, it started kicking me off every time I  connected wirelessly with my Gateway Laptop. AT&T tech support has been no help on this for the past two days. I am review the latter posts of this thread and hoping some of your suggestions will help.

I would make sure you are not losing sync, from what it sounds like, it sounds as if it's a dsl sync drop problem. DId you put the filters back on the line?

I too, am having ERR_DMA issues resetting my DSL connection several times per day.  AT&T has been here and claims nothing is wrong.  I have been searching for a solution when I finally stubled on this thread.  David, your replys have been the most understanding and helpful yet.  Thank you.  But I still have the problem.  I am running WEP.  Channel 11, it was channel 1.  I am in a rural area no other wifi networks within reach.  I have two dell laptops, one macbook, ipad, ipod.  I do not have any correlation between devices and the problem. (But I'll work on that, its a little difficult with 4 users)  It seems from your posts, there are many possibilities to a solution.  This basically tells me we do not understand the root cause of the problem.  (I have a case into 2wire, but havent got a response).  So my question is, is there another AT&T router/modem besides a 2wire that does not have these issues (or other damming issues)?  For me, I would just prefer to replace my 2wire with another manufacturer router/modem and be done with it.  BTW, if so, why wouldn't AT&T be suggesting replacing the router/modem?  There is an aweful lot of service going on over this problem by AT&T.

NOTE: this occurred last night at 4:14 AM, these all correlate to ERR_DMA in the training statistics & CRC errors.

Is there a way to dump the log to a file and sort on time? This log is grouped up weird.

 

Edit update:  The Macbook was powered off last night, out of battery.  The ipad was powered off.  This leaves the 2 dells (one vista, one win 7), ipod and oh yes hp printer 7200 on my wireless network.

 

BTW: daylight savings kicked on my 2701 today!  One day early....  Its getting time from NTP @ 2wire and adjusting for daylight savings automagically...:-) time zone is correct.  Or maybe I slept through today and its really tomorrow...

I'll try the stuff provided but only for the sake of others who may have the issue. I've gone ahead and began the process of getting service elsewhere, and will be canceling my AT&T account this week. After all the things over the years I can't bring myself to understand why I've stuck with this service for so long after having so many ill handled problems, let alone pay far to much for the uncompetative speeds provided to my area, when I keep being forced to use less and less of the service I'm hardly getting. This whole modem ordeal is just the straw that broke the camels back.

 

"Truthfully if it is a power supply problem, it should  be present whether wired or wireless. Not just wireless and not when you turn on a specific device. Otherwise the first device you turned on via wireless should have failed too. "

 

I can see where it's reasonable to believe that, but in thinking about the issue over the last few nights and I've had computers in the past with power supply issues that acted the same way. Computers that would turn on fine and work great until power consumption changed due to trying to play a game or photoshopping things for school, only to have them crash. So its not unreasonable to think that the modem would be just fine with the wired connections if the wi-fi isn't being used, the wired connections aren't drawing nearly as much power. And if the issue is somewhere between the supply and wireless connection itself, then theres a pretty good chance the wired connection wouldn't be effected outside of the complete loss of connection caused by the wireless crashing the modem.

 

Look at it this way: These gateways are like those TV's with a VCR or DVD player built in. The player goes and the TV could still work for years. Sure, the TV could take a nose dive but theres also a pretty good chance nothing will happen. However, for whatever reason you bought that unit, you probably bought it with the express intent to use that built in player -so having a half working device is going to start to feel like a waste of space, and a pretty big inconvience when you can't use it for what you've intended to use it for.

 

You can also look at it like this: The wi-fi is, for whatever reason, suddenly drawing so much power that the modem is making an emergency shut down. If the thing is designed to combat overloads that would lead to potential fires, then any overdraw in power it deems to be too much is going to hit the killswitch, even if its for a second.

 

Also, like I said, its not just 1 specific device, its 3 seperate devices causing the crash whenever they're on, and its usually in conjunction with it being on along side one of the 3 wired computers in our house . I even went as far as to buy a used DSi (which I'm going to be able to return) to test the issue, to make sure that its not an inside job, and it crashed the modem -and a DSi is FAR from being a wi-fi juggernaught.

 

I also want to pose this question: If it isn't something hardware related, then why would this happen with 3 different devices so suddenly?

 

Theres been no updates for the modem's firmware (and there aren't any now), nor has there been any updates with the devices to make their connection to the wi-fi different. Theres been no change on our end PERIOD, before the issue popped up and we have been using the wi-fi consistantly for over a year. I don't see how it could be a settings/software issue, and I'd like to know how it could be, just so I can understand it for later reference.

 

Any way, before I go try any of this, I have to say I probably won't be able to try the thing mentioned to help the console. In looking for thing that might allieviate the problems I went into my 360's settings, which somehow resulted in deleting the profile of my modem. Now, the Xbox doesn't even see that the modem exists in the world.

 

The only way I know of to make it see the modem so I can go throught he process of setting up the profile again is to have a device on that keeps the wi-fi connections open -and I think you can see the obvious problem with that: If I try to have more then 1 wi-fi device on at any time, the modem's going to crash and I'll need to turn off the xbox and the other device in order to allow the modem to cycle and restart properly, losing every chance I had at getting anywhere in the process.. And since I can't seem to find a way within the modem to turn the wi-fi to a setting where its always on, I'm not sure how i'm going to get around that.

For those following this thread... check out http://forums.att.com/t5/Routers-and-Home-Networks/AT-amp-T-2Wire-2701HG-B-Disconnects-Drops/td-p/27... It provides more information and some solutions, including a better modem by Motorola. Could be worth a read.

@desmolift

Either that link is wrong or that threads been closed

 

@David

 

Tried changing the channel (theres only 11 on this modem by the way) but it didn't help, none of the devices would connect to the wi-fi at all after the change and reboots. It was as if the devices didn't know the modem existed (this goes for the 3DS' and the test DSi I bought, I still can't connect long enough to see and set up the modem over the 360 -see my last post for those details), tried to see if something in their settings could be changed to see a different channel but I couldn't find anything that looked like it.

 

As for those links to the programs that I could use to see how many devices are on the connection, I either couldn't figure out how to use them properly, or they just couldn't find my wi-fi connection period -probably because the connection is closed without a device starting it up, which just crashes the modem any way and completely defeats the point.  All either of them really said were "no wireless adapter found", which I assume is because the connection isn't on all the time, and since I don't have a clue how to properly use these programs, because I'm obviously not an expert in these sort of things, I don't know really what good it is telling me to use them at all.

 

All in all though, if MAC addresess are any indication, and I'm assuming they might not be, the only devices that ever connect to my modem are the ones in my house. I'm guessing however that I'd be told that it doesn't matter and other devices could piggyback onto the signal/channel without connecting to my modem, so I don't know if I've already answered my own question with that or not.

 

As for changing IP addresses, I had a difficult time following your steps to change the base IP, since I can't connect to the wi-fi without the modem crashing.. Since the issue is getting worse and the modem won't accept ANYTHING at all connected to the wi-fi connection without a crash (a developement that arose AFTER my post the other night, when I started to try these things), let alone while a wired computer is on with a wi-fi device (like I think I've mentioned), I really couldn't do step 1 exactly like you wanted.

 

I did try changing the base IP just through one of the wired computers with no wi-fi connection on (because I can't figure out how to turn it on without a device doing it for me) but again the devices acted like they had no clue the modem was even there. Actually, in this case the modem stopped the wired computers from connecting to the internet completely (didn't crash, just wouldn't find anything).

 

All in all, all we can do now is only use the wired connections. Its gotten to the point where we can't connect anything to the wi-fi even for a short time without the modem resetting, and its greatly limiting the use we usually get from the internet. In fact, the wired connection seems to be much faster now that the wi-fi really can't seem to be used at all... So, not really sure what you want to make of that.

I think the link is busted, cut and paste doesnt seem to work.  Go to support/communities and search for ERR_DMA in the search box, that will get you to three threads of interest. http://forums.att.com/

@BoomingEchoes

Have you checked your modems Statistics? If not got to, http://gateway.2wire.net/management, enter your system password and click on DSL Diagnostics. There is a table of data there, check the column Exit Code for ERR_DMA. If you can screen shot it and post it.

Supposedly from what little I know of the error/exit code of "ERR_DMA" is suppoedly it had something to do with the 2wire potentially being in the "wpa-psk and wpa2-psk" However I had another chat with another peer of mine tonight, Someone mentioned also going in and turning off the packet flood inside the 2wire. Now one thing I had a notion of trying with a spare 2wire I have is unchecking all the packet detections the 2wire does on the firewall and see if that makes a difference.  Most (not neccsarily all) don't normally check for these things (least my linky/dd-wrt never did). That might be a key as well. 

 

Another thing is also try changing it to WEP and just 802.11b- from some people I have heard from that seems to clear up some wireless issues as well.

Edit to add:

 

I have another 2wire at the house here, I have done some things to it that may either fix or potentially help with the wireless drop problems. If it does I should know more within the next day or so.
