Re: My 2wire modem/wifi keeps resetting

@Markh

I wouldn't waste too much time on this, as I have already done so. :-) Here's a quote from 2wire.
"There are a few known issues that can cause the modem to lose sync due to wireless, one is a known issue with online gaming over wireless, the long timeouts expected for streaming to the game servers can cause all the DSL sessions on the ADSL network to be used up, forcing the modem to reset the connection to clear up more.
Going into "Firewall" > "advanced settings" and turning off "excessive session detection"and selecting strict UDP session control will usually fix the issue and sometimes not require the wireless B only fix.
There are also some situations where a bad line that's being over taxed can cause the modem to reset it's connection, and lowering the wireless mode restricts bandwidth usage available and can help resolve the issue.
Generally moving to wireless B wont effect speeds as most DSL providers do not offer any speeds above 6mbps, so the available speed would be maxed out long before the local network, I can indeed slow things in a multiple computer environment though
Another issue could be the modem it's self, an ERR_DMA exit code simply means the memory buffer reserved for the DSL modem portion of the router has experience a memory leak, or buffer overflow, and had to attempt to retrain the connection again.
One thing to look for would be to go into the Management Diagnostic Console (gateway.2wire.net/mdc) and click on "detailed log" link all the way at the bottom of the left side, there you can filter by "ERR" and "ALL". Look for any errors that are under the heading code of "krtlock" as this indicates a hardware/firmware issue where the modem's firmware kernel is locking up, forcing a system reset.
Multiple krt_lock events almost always relates to failing or defective hardware inside the modem and would require an RMA/Replacement. "

They clearly have issues with the 2701 and do not appear to have a fix as I have requested one. If you are getting ERR_DMA all bets are off. I get these issues with just email and surfing nevermind gaming. To get by try changing your wireless to B, and either buy a new modem or demand a "new" modem from AT&T. BTW AT&T recognizes this problem and are discontinuing the 2701, replaced by Netgear! I was told they are going to be shipping next month. I talked with retention at AT&T and got them to refund me $100.00 for the 2701 and I put it toward a Netgear DGND3700.

Re: My 2wire modem/wifi keeps resetting

I recieved my Netgear DGND3700 on Monday.  Installation was a snap.  I am running 1.17NA firmware, this required an upgrade.  The DSL connection has been stable all week, as well as all wireless connected devices.  So far, I would recommend this modem.  Unfortunately its not cheap at $180.  But with the refund from AT&T on my 2701, its like getting it for $80.  It also fixed my WPA2 problems and allows me to separate my G network from my N network since its dual band.  So far a great device, but time will tell.  I'm so happy my 2wire is back in a box!

Re: My 2wire modem/wifi keeps resetting

Sources have told me that the 2701 and other "legacy" gateways and modems are being replaced due to the need to support the IPv6 requirements that are being pushed out  as we consume all the IPs available in a IPv4 world. The 2701 has been in the field for almost 5 years and pretty solid for a gateway this old, yes modern day apps like WOW and others have maxed out the modem's capabilities it sounds like, but these apps and such were not there when it was built. It is a lower cost gateway and that is what AT&T wanted then my source told me. I also heard that the 2Wire or Pace as they call themselves now also have a N gateway with extra memory and mutiple processors for todays users coming out or ready to be sent out. Guess we will see it whenever AT&T lets it out into the streets.

 

 

 

 

 

Never a dull moment, if there is there will always be drama to replace it..

Re: My 2wire modem/wifi keeps resetting

I have got a confirmation that the pace 4111n (the 2wire replacement) should be hitting the field if not already and will not have this problem and the test units are passing all tests they can think of currently. I have also heard from another colleague that apparently 2wire might not be the only one that has this problem He states he was at a microcenter over the weekend and heard of a lady complaining about the same thing with a linksys router that she had (apparently a befsr41 router) and described the same problems that we have been seeing. She was having these problems and the tech at microcenter states since april of this year (2011) Microsoft and Apple released an update to their operating systems for IPv6 to be enabled. the microcenter person stated that since then people have had to go out and buy IPv6 capable routers this year to get around the problem, or disable it in their own operating systems. So far with my DD-WRT router I haven't experienced this problem and I have 2 machines with win7 on them about around the same time sp1 came out. Now the only guess I can think of is, is sp1 of ddwrt v24 is ipv6 capable. So maybe it wasn't affecting me after all.

Yes Pace has confirmed that the 4111N for adsl is out and about, Mr. Chun Pace directror of marketing replied.

 

Is there any info from AT&T where and when and what this device is in an available model (it is not at at&t/equipment although was rumored to go on there Nov 1. Thank you!

Re: My 2wire modem/wifi keeps resetting

I'd be careful that the Pace Router isnt just another 2Wire... they are the same company now.  I believe AT&T is also qualifing a Netgear product.  I'd go with the Netgear if you get a choice.

Re: My 2wire modem/wifi keeps resetting

Someone sent me a message earlier today asking if the pace 4111n is a gigabit ethernet router as well. I don't have the correct answer at this time but I will advise when I have that answer in more detail.

Re: My 2wire modem/wifi keeps resetting

ok, according to my sources the new pace units will not have 10/100/1000 but just 10/100. As well as most of the netgear units I confirmed are 10/100 as well. This one isn't much of a shock to me as I have my own gigabit ethernet router and my dsl runs through just the modem.  I haven't seen any really good quality gigabit ethernet routers hit the market either. The one I was considering (a linksys e4200) apparently gets bad reviews with the router giving out after only owning it a year. 

 

dd-wrt and even m0n0wall has a listing of gigabit ethernet cards they will support. part of me kind of wants to go that route, or see if dd-wrt (x86 version) goes that route.

Re: My 2wire modem/wifi keeps resetting

Wow, wish I would have searched google for the answer to my att 2wire modem recycling a couple months ago when I first had issues.  I've had a tech out 4 times and each time it's working fine for them.    Always thought the issue was related to signal or on their end.  Just read this article and tried turing off/on the wireless on my iphone.   As soon as I turned it on and watched a Youtube video the modem cycled off and on!   I remembered that I had recently turned up the power setting to try to remedy our Wii not always connecting wirelessly.  So I turned it down from 10 to 5 and that fixed the problem.   Found that I can turn it to 8 and it looks like its not having any issues.    I used the inSSIDer software to verify that channel 5 was not being used by anyone else.  Thank you for your help!

Re: My 2wire modem/wifi keeps resetting

cool, glad it fixed yours. truthfully if the signal isn't that strong in a certain part of the house, I would get a cat5e wire and set up another access point. 

 

I have been looking into one of these to replace an AP that has been giving me problems for a while now. This would work for the 2wire as another access point and you could mimic your 2wire and have essentially the 2wire signal penetrate more of a home structure that may not be the most wireless friendly. One cat5e cable placed correctly and in the weak spots can make all the difference in a wireless network.

David: AT&T's specs for the Pace 4111N just read "high powered".  Would you say that is equal to N150, N300 or N600 "high powered".    Also, is the above rumor of AT&T selling the DGND3700 true to your knowledge?
