Ga_Peach: Not sure if you figured out your issue yet, but that looks like utilization to me, due to your high ping times and small amount of packet loss. You'd want to isolate down to only your computer connected to the modem/router with no wireless devices connected, and try then. There's also a great free program called PingPlotter that'll help show where your issues start happening. Combine that with watching your bandwidth usage and utilization, and you'll likely find the issue.
abbzer0: Thanks for sharing. Hopefully, that will help others. My particular issue happens when isolated to the modem (I've tried 3 different brands) with a lan cable. The drops occur in communication between the modem and WAN Gateway IP on their first Layer 3 device past the DSLAM.
Regarding my specific issue as I reported, I'm still working with AT&T on this and will report back if/when they figure it out. My entire circuit has been reprovisioned and the issue remains.

My internet for the past month has been a fluffy, cornball, piece of poo.
When downloading something, sometimes it will reach speeds of like 100 bytes per second.
YouTube videos stop after 3 seconds.
I have to constantly refresh web pages.
Basically, nothing is really working like it used to before.
I've even completely reformatted my Windows XP.
Any help or ideas?

I not trying to be smat about the power, but the power supply/transformer for the 2710 does not event have a ground lead on the plug.
Well, my 2701 has the hoped-for ground-lead plug... I know what you mean, though--the idea that a power strip might be negatively affecting the operation of the modem seems as wacky as they come......BUT I'll not discount it as stranger things have happened. Still, considering the fact that the modem is a couple of *feet*, at least, physically removed from a power-strip plug, an interference problem doesn't seem likely and the idea of voltage fluctuation with anything *except* a wall socket seems positively bananas! Yet, it could be a problem in the modem's psu that only manifests when Martians happen to do a fly-by over the neighborhood, who knows?
I had a somewhat different problem, though. I installed the 2701 about four months ago--first time with DSL--had been on cable for ~12 years--we moved and had to switch as there is no cable here. Although the DSL modem would rarely drop its connection for just a few seconds, what most often bothered me were two things:
1) The modem was constantly dropping connection speeds on a regular basis, prompting me to do a diagnostic reset of the modem as the quickest way to set it back to normal (I have a 6mbs down line that was regularly dropping to 3mbps, or so.)
2) Under Network devices in the modem's setup, two phantom devices showed up--two more devices than should have been there, with phantom hardware mac addresses to boot. The modem had been assigning IP addresses to those two phantom devices from the first time I plugged it in. I even tried to clear the modem's bios by resetting the network device configuration, but from the place in the configuration software for the modem that I had been using to clear this portion of the bios--the fix only worked temporarily and within minutes the phantom devices would be back.
Almost comically, my Google/Bing searches led me to exactly one post written by another person who'd had a 2701 and had also gotten two phantom devices with their own phantom hardware mac addresses and sequential IP addresses. No one could help him, and even 2-Wire concluded that what he needed was a new modem as apparently the appearance of phantom devices in the network is a harbinger of impending electronic death for the 2701... I really thought for awhile there that I must have gotten *his modem* after he sent it in for replacement (and it was put back out for public consumption, of course!)...
Eventually my searching led me here, and precisely to this thread, wherein I discovered another way to get into the modem's bios than the one I had been using. The mdc access provided me with options a bit more advanced than the standard method of bios config access afforded, and the reset button under Network Devices worked the first time--and the phantom devices have not come back. That was the good news.
Bad news is that the modem is still dropping from 6mbps to 3mbps regularly. I only rarely actually lose connection--the modem simply drops down to 3mbps. I was hoping that if I ever resolved the phantom device problem that it would also resolve the DSL speed shifting. Such is not the case, apparently.
Here's a cut & paste of my diagnostics, should that prove helpful to someone in trying to armchair this thing:

Wanted to chime in on the phantom device phenomena--did a lot more digging into that yesterday, and it seems as if what actually might be causing those is some funky network-active software Microsoft is running in its server versions and in Windows 7. And I was relieved to see that many more people were also getting these as I discovered once I Binged the actual hardware mac addresses that had been popping up--all *kinds* of routers and gateways were reporting the identical mac addresses as appearing from phantom devices, too! Hallelujah--at least I made some progress and discovered that the 2Wire modems were not unique in this regard and that this is actually a fairly common occurrence. Of course, it would have to be, since Windows software is also a fairly common occurrence.
What seemed to be the general consensus from all side after lots of head scratching and investigation, is that some of the network-aware services in Microsoft's server platforms and Windows 7 were creating "fake devices with fake mac addresses" for internal reasons known only to the geniuses responsible for this software (and I mean "geniuses" in the most complimentary of sort of way.) The phenomenon occurs in versions of Server 2003 (where the entries used to show up as "detective e1:6c:d6:ae:52:90", etc)., and occurs when certain services are running in a network situation under Win 7 (x64 in my case.)
Of course--there is *no* clear-cut documentation from anywhere telling us which services do what--that would be far too easy. So what I had to do yesterday is laboriously examine every service from A-Z on an individual basis. If I had a service running that wasn't absolutely necessary--by that I mean no other services were dependent on it and I could stop it without ill effect or a warning that many other services would be shut down, too--then I'd stop the service and set it to manual.
I'm not running wireless--so I also stopped any and all WLAN and other wireless-related services. I wish I could tell you which one of them had been creating the fake network devices--but I can't. But in researching the issue yesterday, no one else could tell you, either... We are all agreed, however, on the problem being caused by a particular Microsoft service.
And that's just it--we don't even know if this *is* a bonafide problem, but if you are like me and you would prefer it if your network did not report phantom devices with fake hardware mac addresses, then Microsoft--AT&T--somebody--needs to get very, very clear about what's going on here. Can you imagine the amount of customer frustration and help desk angst that this single issue has probably caused? Billions of $ in lost productivity, I'd wager. Just Bing/Google "e1:6c:d6:ae:52:90" Without the quotes and you'll begin to get an inkling as to how big this problem is.
Anyway...after shutting all Win7 x64 services that were no -essential to my network down (set them to manual--if they are needed they will come on in that case, usually), and doing one more reset on my modem's network device list, my phantom devices are *G_O_N_E!* They've been gone for two days now, through several reboots and several 2701 power cycles--so at this point it *appears* they are not coming back. I just wish I knew which service(s) it was responsible for this needless waste of time.
Still on problem remains, however: my 2701 is still shifting speeds and I have to manually do a diagnostic reset of the modem to get back into 6mbps down territory--it still wants to donwshift into 3mbps mode onm a regular basis. I always check this and if necessary correct it before I do a download of a sizable file because what's the point of having 6mbps down other than that?
Hope this helps someone...and I wish someone could help me with the constant speed-shifting between 3 & 6 mbps that I've been getting since the service was installed.

Thanks waltc... had suspected a Windows problem because when I log into my terminal server at work, the problem is 10 times worse. It is Windows Server 2003. But it's the modem, too. I got tired of screwing with it and bought Netgear N300 DSL modem. $129 at Best Buy. Everything works now...streaming movies, logging into my offices terminal server, etc. It's well worth the money to me.

I'm still hoping someone will help me with my initial post.
The results I got from http://www.speedtest.net/ are 0.67 Mb/s for Download, 0.26 for Upload, and 70 ms for Ping.
My internet seems to stall every few seconds which makes websites time out and for downloads to end all together.
I can perform and post any additional tests that could give you more info on this trouble of mine.

I have been having the SAME problems with my 2-wire for almost 2 yrs. & have had MANY phone calls to AT&T customer service & Even Customer Retention to no avail! Does anyone know anything about comcast cable's xfinity high speed internet?

Glad to say it looks like my problems have pretty much straightened out over the past weeks. I cleared the 2701 bios once again and this time the "phantom devices" it had been registering are gone for good.
I also began accessing my gateway through this link:
instead of through this one
I know that it seems like a case of pure semantics, but I know that my 2701 gateway performs better and most closely to its intended specifications when I use the first link instead of the second one... There is some logic to this, though. The MDC link requires my password for the modem whereas the standard bios link does not. Through the MDC access I've been able to more precisely reset selected portions of the bios as needed. Problem solved. My sync to 6mbs down is much more stable than it had been, and now most often always stays where it should be as opposed to changing speeds constantly forcing me to reset the gateway. Things are definitely improving as of late!

I have Ipad and Acer laptop (Windows 7) connected via 2wire to DSL.
About 10% of attempts to connect to web failed.
As suggested, changed Wireless Mode from 802.11b/g to 802.11b.
2Wire works fine now, actually seems faster (not as predicted).
Thank you for good suggestion.

OK, so I've had ATT DSL service out here in rural Georgia for about 11 months now. One annoying thing is that the connection would drop, randomly, and take several seconds to re-establish. Worst part about it is when I am using VPN to access my machines at my workplace. The connection burp often would confuse the VPN, leaving me to take a couple of minutes to reconnect each time.
I have 6 Mbps service using a 2Wire 2701HG-B. Reading the statistics, it's pretty clear that I am seeing a DSL Link Retrain. I see 320 DSL Link Retrains since the unit has been up in the last 18 days 4 hours -- or about 17.5 times per day.
One problem with the link retrains is they appear to happen randomly, so it is impossible to tell when you "fixed" the problem. However, this morning I was able to cause the link retrains to happen at least 7 out of 8 times, but running the test at SpeedTest.NET. There, I just did it one more time for 8 out of 9 times.
The download test proceeds perfectly, giving just over 6 Mbps as expected. However, each time the upload test starts, BLAM - link retrain (internet light goes dark, DSL light blinks red, then green, then solid green and internet light goes green). Sometimes it will retrain more than once. And on one of the nine occasions, the upload test never did complete.
Great. Now I have a reliable test. I'm going to try some of the tips I've seen here and see if they make an difference.
I've already changed the Packet Flood Attack Detection to off, but it makes no difference.
06-16-2012 12:46:00 PM
By using the reproducable test case of the SpeedTest.net upload test, I was able to experiment. My results:
* Moving the power supply connection from a power strip to the wall had no effect.
* Switching to 802.11b wireless networking (11 Mbps) appears to fix the issue. I could not get a re-train failure in 5 tests.
* Switching to 802.11g wireless networking (54 Mbps) caused the issue to re-appear.
* Using a 12 Mbps speed limit on 802.11g wireless networking appears to fix the issue. Five tries, no re-train failure.
* I tried 24 Mbps speed on 802.11g -- failures.
* 18 Mbps speed on 802.11G -- appears to work five tries, no failures.
From these tests, it appears the problem may be due to an internal design issue. Uploading at high rates of speed appears to cause the retrain. Throttling the speed back less than 24 Mbps appears to bypass (but not fix) the issue.
I don't like running my wireless network at less than 54 Mbps, mainly because I have other devices (iPhones, iPads) that do wireles synching, and it seems a shame to slow them down. But, if it means my internet connection will stay up and quit burping, I'll suffer with it.
The best solution may be to disable the wireless feature of the 2wire 2701HG-B and connect an inexpensive wireless access point to the wired ethernet ports. Unless that causes the retrain issue as well....
06-27-2012 05:28:48 AM
My 2wire was working fine until I connected a phone land land phone in my computer room and then the drops and disconnects started. Turns out I unpluded the 2wire filter and that solved the problem. I have never had a filter on this line becauce I have never had a phone in this room. It is something to consider

glassheart828: Your "packet flood" trick has done a great job for me. I came back here to visit again as it's summertime and the DSL was going crazy again, 50, 60, 70 disconnects a day, a lot of them in rapid firing mode, off and on several times in the same short time period (this, after a blissfully quiet winter with no outages). I had more conversations with more techs, knowledgeable people who seemed to have the right answers, all to no avail. (One told me that having the DSL plugged into my computer as an Ethernet when it could also connect wirelessly was confusing the modem, disconnected Ethernet, no change; another said that when my DSL line had been moved up on the board, the concommitant software had not been installed; she installed it to no avail.) So I stumbled onto this post and realized that the "packet flood" solution made a great deal of sense (as had most others), and what the heck, at this point I would readily suspend my modem from the ceiling with bright Christmas lights if I thought the problem would be over.
I performed this change on Monday morning and reset the computer. It has now been nearly 48 hours since reset and I have had a total of 13 disconnects --- but here's the thing: ALL of those have occured when the computer was set in hibernate mode. I have not had one outage while I've actually been using the computer. It may not sound like much but for someone who has been experiencing the frustration of constant blips, this is a miracle.
Thank you, glassheart828, for posting this amazingly simple fix. Yes, I also went back to 802.11b so that helped, too, but the packet flood setting was genius. I suspect that all of the suggestions and maintenance I have followed over the past two and a half years have not been in vain, but that this modem is tricky and you just need to find the right fix in order to overcome whatever is making the modem disconnect. Maybe you have to do 38 things before you find the right one, but this suggestion unlike all others, has made the crossover to error-free online time for me. I am forever in your debt, and if you need to tap my computer-saturated brain at any time for any reason, please feel free. At least I have learned so much more about computers and modems and tech tricks than I would have otherwise, and all lessons are valuable.
BTW, if the modem starts dancing again, all bets are off!!
07-04-2012 10:42:13 AM
See my posting. 802.11b probably did most of the work, since it limits the speed of the wireless connection to 11 Mbps. You can run 802.11g, but you've got to change the speed limit to 18 Mbps or less.
I changed the packet flood setting with no effect.
I'm convinced it's the wireless speed that causes the router to reset.

My thanks for All posting on this thread! We have suffered with this malady-- everything y'all say-- for about a year and a half. When we first got the ATT DSL, moving from a rural area, we were thrilled, all worked well for a year. Then the awful disappointment started. ATT tech support is always polite and seemingly attempts to help, but they don't have a clue. They sent us a new modem, had line people come to the home, finally ran a new line from outside to in-- all only after we pitched a fit. The new line did help some. Our disconnects were not as long. The disconnect happens so quickly, couldn't catch the lights on the modem. My Mac affected the most. Disconnecting every few clicks on the internet.
I did exactly as sgreen002 instructed last year, 7-26-11. If this does not fully solve the problem, we'll get a new modem asap. I am hopeful. It is a miracle that I plugged the 2wire and disconnect into the search engine and found this forum. You know what we say in the south?-- bless AT&T's heart. I learned so much here-- THANKS!!

Just switched to U-Verse and was having huge issues with this router. Nothing wrong with the att service what so ever, just issues with the wireless capabilities of this unit. How to fix it:
Add a router that you know worked before - First, turn off wireless broadcast from the 2wire. Move to new router, change settings in new router to have an IP address begining with 10. so you have no conflicts. Use a port from the ATT gateway and wire to the internet port on "new" router and reset it.
With the fix, disconnects from wireless are compeletly gone and internet is actually DL at 11.50 MBPS
09-18-2012 03:53:34 PM
If any of you have read my previous posts, you will know that I had constant disconnects with this modem for over two years. I did EVERYTHING (see previous messages) to no avail.
One day in July of this year, the disconnects STOPPED. I did NOTHING to any part of my computer, modem, wall switches, lines, phones or placement of the modem immediately prior to this cessation. They just stopped.
I monitored (as I'm still doing) the modem disconnects in the past two months and although there have been a few (the last one was a week ago), it is nowhere near the 50 to 100 per day I experienced before this miracle. The whole system rebooted about a month ago and I had several outages, but nothing that actually disturbed my Internet surfing to any great degree.
I can only imagine that ATT did something to their lines or equipment. To me it means that all the handstands, headstands, twisting, bending, buying and hand-wringing I did was for naught. It just got fixed with no input, no recent request or imploring to ATT. No one in the repair department knows anything about this sudden restoration of service.
It's karma, I just know it. I'm really a good person after all.
