2701HG-B Frequent loss of Internet light, and now rebooting

I've been searching and following directions in numerous posts here. when in the management screen, the 2wire seems to reboot on its own (no I didn't hit the rest buttons - LOL!). UPDATE : WHEN I CLICK ON DETAILED LOG - IT REBOOTS THE 2WIRE!!! HELP... what I noticed is that most of the time the system disconnects, my wife is on her wireless Macbook Pro. that is just about the only times it happens..it may happen seldom if she's not on. here are my stats, I am using a 2701HG-B with updated firmware (I think) any help is greatly appreciated:

thanks Koma, but this has happened on my previous desktop as well, so I'd think it'd be rare that I got same attack on 2 different computers. this one is brand new Dell. I'm pretty advanced at troubleshooting and keeping system "clean". I suppose it's possible. will keep checking.

North Richland Hills, TX
The attack would be against the 2wire init itself not the computer. if that helps.

ok, thanks. link didnt seem to offer any real solution to the problem though. I guess if that's the cause, not much I can do.

North Richland Hills, TX
well disable netbios and remote mangement and any unneeded srvices in the mdc console and change the default ip scheme to somthing else is a work around i think. as it disables the default »home and »gateway.2wire.net urls for accessing the 2wire so you would only be able to acces it with your new ip sceme.


Fort Lauderdale, FL
would you believe it if I told you they are already disabled. LOL. this problem just keeps comimg back. also seems to have started when I started with Vista. must be some kind of poisonous combination

Is it your wireless connection keeps dropping or does the power light start blinking? Your post doesn't really state what exactly is happening and you didn't provide us with your DSL Diagnostic page and details log (I don't know what your uncancelled echo is and etc.).


Fort Lauderdale, FL
it is not a wireless issue, it is a dsl issue. it appears that whenever my wife signs onto the network (runs IE or Safari on her MacBook PRO), it knocks out DSL off. the Internet light disappears, and it then finds the signal again. sometimes, the DSL light goes red, then resets as well. I can't print a details log, because the system reboots every time i click on it. here is the best I can do :

Now, here's the wierd thing I just saw for the 1st time. up until a few minutes ago, my device list was showing the customized names I had entered so I can identify each. Now it shows the following :

System -- 00:0d:72:89:8d:81
DAD Ethernet 00:c0:4f:04:80:bf
NT4_SERVER Ethernet 00:c0:4f:0d:a5:45
WIN98 Ethernet 00:c0:4f:0d:e7:a6
mom Ethernet 00:c0:4f:1d:62:35

Here's the thing. these aren't my codes, but they might be my son's Macintosh. I have NO computers with windows 98 on them, and none of these computers are connected via ethernet except mine!

this is ridiculous. HELP.. LOL.

I would recommend factory reseting Your gateway(hold in the red reset button for 10 seconds , make sure you have your ISP username and password handy to reprovision the gateway) After reset run the system setup (gateway.2wire.net/setup) and put in your username in password. After you have green internet light verify you can surf then see if you can access the detailed log. If so please post detailed log

I'd do what ColonelPanic suggested but instead of 10 seconds, hold the reset button in for 30 seconds (10 seconds is too short of a time).


Fort Lauderdale, FL
thanks all. I have reset the modem quite a few times, additionally, as mentioned, I have 3 others of the same modem (long story) and it happens on all of them, so I'm still thinking there is a setting or something that is @#*%# everything up once the macbook enters the network. is this possible?

BTW - any issues with my statistics?


Fort Lauderdale, FL
anyone else have any solutions? it appears it definitely relates to the MacBook entering the network. We are working awesomely without the MACBOOK on, but once connected, all hell breaks loose.

I've been fighting with dropped DSL connections for over a month (and 3 different Qwest 2701 modems, on 3 ports, on two different DSLAMs). We have a small office network with a couple of wirelessly connected macs, and a few wired windows PCs.

In the last few days it has gotten worse. I've been having it reboot spontaneously often, including when I access various admin pages (like the admin home page). Resetting to factory defaults seems to help with the spontaneous reboots when accessing the admin pages, but only for a little while. This last development helped convince me that these things are garbage.

The only thing that has given me any hope is this morning I reset to factory defaults and then set it to bridge between the ethernet and the DSL connection, then I took an old WRT54G I had at home and set it up as the router/firewall and to authenticate over PPPoE.

For the first time in a long time, I've seen 0.5% packet loss on my test pings. I don't know what the problem was, but so far, it seems that relieving the 2701 of doing anything other than bridging the connection has made it much healthier.

I'll see how it looks over the next few days. If everything checks out, I'll order a cisco router/AP/DSL Modem and send this piece of junk back. If it isn't better, I'm probably going to cancel service.


Fort Lauderdale, FL
please keep us updated.

did you ever try the 2wire first with the PC's then see what happens when MAC enters the network?

Carriere, MS
There was a relevant thread in here that I can no longer find, but it had something to do with the Macintosh using a character set in either its DNS requests or its DHCP requests which could cause some routers to reboot. I searched for it with no immediate success, but this may be another possibility to investigate.

As I recall (fuzzily), there was some Mac configuration form where the problem could be corrected.


reply to wassy
Had the same problem......fixed it by junking my 2Wire and bought a D-Link all in one router/modem at Frys.

My DSL works perfect now....no problems and no reboots.

Hi Jacko, I am happy to hear that you resolved your problem by replacing it with D-Link unit. My friend also has the same problem and she asked for my help. Which D-Link model number did you purchased to replace your troubled 2Wire unit? Did you follow the D-Link instruction given here at dslreports - »AT&T Southeast Forum FAQ »How do I properly set up a D-Link Router with a Westell Modem? -?
Easy setup or hard? I would appreciate if you can post your response in this forum this week because she would love to clear this ongoing problem quickly. Plus I am sure many folks out there would like to fix their constant 2Wire problems. My friend is not technical so I am hoping I can help her out.
Thanks for your help.
