Internet drops/cuts out every 5-10 mins or so. Get booted from connections etc...

[greenxeyezz]

I thought this would be better with its own post rather than trying to tag on to a 100+ post thread.

I have ATT Uverse 12mbs package. Phone is NOT VOIP and no TV through ATT.

I constantly get booted from online games / disconnects from servers. Downloads go from max speed to 0kb/sec then I need to reload the download or just wait about 1min for it to pick back up. Streams constantly buffer every so often (netflix/youtube etc)

So i downloaded that UVReal time and a bandwitdh monitor to prove this is hapenning. I need to know how to fix it or if its just the way it is with ATT. Cause if it is JUST the way it is, they are gone and not paying for them as of yesterday lol.

As I was writing this post and putting the images up, the internet "stopped" working again, causing me to reload again.

I have reset the modem (hard reset) and I am DIRECTLY connected. 

[texasguy37 ACE - Champion]

Are you experiencing these issues with both wired and wireless connections?

I don't see any real issues in the screenshots.  It appears that the RG has only been online for about 12 1/2 hours, so the Error Table does not show a good history of activity.

[greenxeyezz]

Yes both wired and wireless cut out same time. 

[texasguy37 ACE - Champion]

I would suggest that you leave the RG online for another 1 or 2 days, then repost the screenshots.  Those screenshots may show a better indication of what is occurring.

[greenxeyezz]

Do you not see those BLACK bars. The Netmonitor shows downloading activity. I queued up a big download. Everytime you see light blue that means its downloading, everytime you see BLACK that means it stopped downloading on its own. I dont think ANY internet should be "cutting" out down to 0k/sec download every 5 mins or so.

I just reset my modem again to see if that would "fix" the problem and it has not. So I guess I need to go 2 weeks with the internet cutting out every 5 mins getting booted from gaming servers to show that something is not right? My first modem with them within the second day was bad, they replaced it, the one they replaced it was "bad" they gave a new one. Internet still sucked. They came out again and replaced something outside on their end. It worked for a bit but I wasn't gaming or testing the internet, just let it go since we just moved. Now that everything is setup its horrible.

Had issues with ATT regular DSL at my old place with crap quality and consistency, went with Time Warner. Thinking Uverse is a better option and better quality we went with that at our new place. Seems to be a consistent factor with ATT. =[. Hopefully there is an easy quick fix for this drops

[greenxeyezz]

Will leave it back up for 1-2 days and will be back, thanks =)

Do you have your computers connected through another router? I see in your screenshots that you've manually put in the IP address of the RG (172.16.0.1). This isn't normally required unless you have an intervening router.

What brand and model is the intervening router and is it running aftermarket firmware like DD-WRT?

If so, you are running into a DHCP renewal issue with DD-WRT. Please configure DD-WRT in accordance with the following guidance:

http://www.comprepairgurus.com/att-u-verse2wire-gateway-and-dd-wrt-router-in-dmz-mode/

[greenxeyezz]

I am running a linksys e3200 on linksys firmware not DD-WRT firmware. I do want to put that firmware on it, but not at the moment. The current DHCP release on the linksys is 10mins.

Connection Type: Automatic Configuration - DHCP
Internet IP Address: 108.234.116.252
Subnet Mask: 255.255.252.0
Default Gateway: 108.234.116.1
DNS1: 172.16.0.1
DNS2:
DNS3:
MTU: 1500
DHCP Lease Time: 10 Min

but it is un editable....

[greenxeyezz]

also, the link you gave me is about changing the firewall on the router...what of these settings (firewall settings)

on the linksys need the changing

Internet Filter Filter Anonymous Internet Requests Checked Filter Multicast Filter Internet NAT Redirection for IPv4 Internet Only Filter IDENT (Port 113) Checked

[SomeJoe7777 ACE - Geek]

The 10 minute time is the lease interval given to the Linksys by the 2Wire. By default, the Linksys attempts to renew the DHCP lease at 1/2 the lease interval, which is 5 minutes.

DHCP renewals are supposed to come from the IP address of the DHCP server, but the 2Wire routers have a bug in them where the source IP address is incorrect, and the Linksys's firewall will filter the renwal packet. What then happens is that the DHCP lease doesn't get renewed, instead it times out, the Linksys generates an interface reset (dropping all TCP connections and NAT translations), and begins a new DHCP renewal. Once the renewal occurs then the interface comes back up, but all connections to all servers have to be established again.

If you can't upgrade to the DD-WRT firmware right now and insert the firewall rule that will compensate for all this, then configure the Linksys so that the WAN IP address is statically-assigned instead of using DHCP. Configure it statically just like your post says. This way, the Linksys won't attempt DHCP anymore, and the interface will stay up.

[greenxeyezz]

just setup to static IP testing this out, thanks for the help on a sunday!

[greenxeyezz]

seems to have fixed it, thanks good fix til i get my DD-WRT firmware on thanks again!

[greenxeyezz]

well i thought it fixed it, now the disconnects just happen and different intervals and longer than 10 mins....=(

[texasguy37 ACE - Champion]

What is the reason that you have your own router connected to the U-verse gateway as opposed to just using the U-verse gateway?  

Would it be possible to remove your router and connect directly to the U-verse gateway to see if the disconnections still continue?

[greenxeyezz]

ZERO control over the network, gigabit network needed for multiple reasons,

here is a new screen shot after a restart.

[texasguy37 ACE - Champion]

You might have some issues with your U-verse system; however, a little over 3 hours of history does not give a clear indication.

[greenxeyezz]

As said its not every ten mins now, so it is bearable to play with and use for now...lol...i will let the internet run its course over the next few days and see how this goes. I wont be at home AS much so i wont be using it AS much but will still see where this goes, thanks everyone for the help its gone in the right direction....

[greenxeyezz]

two days in a row i have to HARD reset (full power off and back on) the RG...

I tried connecting to it MANUALLY and I cannot access the internet or even the webportal, but all the lights are NORMAL on the front. so I cant get more than "24" hours of error reporting....is this ANOTHER bad RG? itll be my 3rd or 4th one since having ATT about a month and a half ago....

[texasguy37 ACE - Champion]

What you are describing sounds very similar to an issue that I had in October of last year with my 3800HGV-B.  Eventually, my RG was replaced with a 3801HGV.  Since that change, I have have no issues.

You might call Technical Support  again to explain the issue that you are having.  If you are unable to get things resolved, send a PM to Alex who is an AT&T Community Manager on this forum.

[greenxeyezz]

So i called ATT and explained the issue. Had tech come out, tell me that it was a wiring issue with the house and not their equipment and would have to charge me 55 bucks for the call. I wasnt at home but my fiance told him "No, we already spoke with att, my fiance (me) already diagnosed the issue and everything is pointing to the modem, it is NOT a wiring issue"

shortly after they replaced my modem with the new 3801HGV and said "there is an issue with your linksys router you should plug directly into the uverse modem and you wont have this problem, bye"

I get home and find the modem replaced and set everything back up, it seems to be working, will try the 18-22hour thing over the next few days and monitor it closely.

Why would it be my linksys router being the issue yet you replaced the modem? Are ATT techs designed to say there are issues with everything but their OWN service to CYA or try and blame us later when there is an issue?

This internet issue is on top of a 5+ week issue with getting an 800 number working. 4 diffeent people promised us within 3 business days and just 2 days ago we were told that we now don't have the proper papaerwork for them to establish the 1800 number. Either the 4 people before were lying or they lost it and the new person is lying. This has been a HORRIBLE experience for us with ATT....

Back on topic, thanks for the help, will keep updating here as my issue progresses

[TonyLima]

I wish the problems we're having were as consistent as some others on this thread.  A few weeks ago we upgraded to uVerse with a Motorola NVG510.  It looks like we have ADSL2+.  We actually didn't want a router as we are very happy with our SonicWall TZ200W network security router.  So we have connected the SonicWall to a port on the NVG510.  After some trial and error and a phone call to SonicWall tech support we got connectivity.  We are only using ethernet as we get wifi from the SonicWall.  I have tons more network information, but I think I'll let the experts here ask for what they need rather than doing a data dump in my first post.  Short version: we have two iPads, an iMac, a MacBook, a WinXP notebook, and a Win7 desktop.  There's quite a bit of network-attached storage. 

The problem is that the connection drops about half a dozen times a day.  It usually lasts for a couple of minutes.  My lovely wife has been doing a lot of video uploading and downloading, so this affects her most of all.  Luckily we have robust software here and the site she's using for video (Vimeo) seems pretty fault-tolerant.

The NVG510 log file contains tons of entries like this:

2012-05-20T09:39:47-07:00 L3 dnsmasq[2487]: no responses from nameserver '99.99.99.53'

2012-05-20T09:39:47-07:00 L3 dnsmasq[2487]: nameserver '99.99.99.53' is now responding

2012-05-20T09:42:23-07:00 L3 dnsmasq[2487]: nameserver '99.99.99.53' is now responding

I will happily and speedily respond to any suggestions.  Thanks in advance for any help.  If Dan Wilson (SomeJoe7777) happens to see this, and the problem isn't too low-level for him, I'd greatly appreciate his input.

Hey, Taylarie, thanks for removing my location! - Tony

[SomeJoe7777 ACE - Geek]

If the WAN port on the Sonicwall is set up for DHCP, try changing it to a static IP assignment instead. There can be DHCP renewal problems with some firewalls. Using a static IP assignment will fix that.

[TonyLima]

Dan, thanks for the advioe.  I assume the static IP address I should use is the internal IP address of the NVG510 (192.168.1.254).  I'll give that a try Tueday.  (If I'm wrong about the IP assignment, please let me know!)

Tony 

[SomeJoe7777 ACE - Geek]

No, you should use whatever IP address is assigned to it now. If you've just hooked it up and it got a private IP address in the 192.168.x.x range, use that. If you did IP Passthrough where it got the outside routable IP address, then use that.

[TonyLima]

Thanks once more, Dan! - Tony

[TonyLima]

Dan, that may have worked.  It looks like I screwed up the initial settings on the SonicWall.  User error -- so what else is new?

Let's not mark this closed and solved for a few days just to make sure.  But things look promising.  Thanks once more.

Tony

[TonyLima]

Sigh.  Spoke too soon.  Just had a complete blackout that lasted for about 20 minutes.  Below are parts of log files from both NVG510 and SonicWall.  This appears to be a separate problem.  However, the original problem returned once we got back online.  Once again, any advice will be followed as quickly as possible.  Thanks. - Tony

[SomeJoe7777 ACE - Geek]

The ICMP Destination Unreachable packets indicate that the NVG510 may be dropping the connection or there is an upstream routing problem.

Do this: Try to browse the internet for 1-2 days with a computer that is connected directly to the NVG510 instead of through the Sonicwall, and see if the problem persists. If it does, then you have evidence that AT&T's service is definitely dropping, and they will have to come out and get it fixed.

[TonyLima]

I'll have to think about that.  If I can find a sacrificial computer, I'll give it a try Thursday.  But I'm reluctant to leave the shelter of the SonicWall.  Thanks, Dan. - Tony
