Details:
ISP: AT&T
DSL Modem: Motorola 3360
Router: NETGEAR WNDR3400
Extender: Netgear WN3000RP (been turned off most of the day in order to isolate issue)
Devices on Network at any given time: 5
Desktop: Running Windows 7 SP1
Setup: In an effort to make understanding easier, just please follow the link below. This is what I configured our modem/router to be this morning and it worked most of the day, but it just went down again...

Background: So we've had this issue for the longest time now with our DSL connection just randomly dropping. At first is was because we lived at the far edges of the DSL line, but now we are well within the area that AT&T DSL goes, but we are still a far way (9994 feet according to ipconfig /all) from the box. Anyway, lately, we have had some very severe issues with our connection. When it drops, Windows troubleshooting always gives a different reason why. From DNS not responding (using Google DNS here) to IP Helper not working correctly.
I called up AT&T and after disconnecting the router so we could access the modem configuration page we discovered that the issue was that our username on the modem had mysteriously changed to some generic AT&T username (attreg@att.com). We changed it back and boom...internet. We hooked it back up to the router with no issues. The internet was up for about another hour and then it failed again. This time for no reason. Username remained correct and everything else was fine in the modem configuration page (after redisconnecting the router) but it. just. wasn't. working...After a few hours the internet came back as suddenly as it left.
The way I've been fixing it is as follows:
Disconnect Router completely from network and connecting desktop straight to modem via ethernet cable.
Turn off Desktop and Modem for 30 seconds each
Turn on modem and press reset for 30 seconds to factory reset it
Turn on computer
Open Chrome where I am taken to the Modem config page (not routerlogin)
Go through the whole process of activating the DSL through the AT&T High Speed Internet setup
And we have internet, but only on the desktop since the router has been disconnected (it's how I am posting this right now)
I've followed these steps twice now and it has worked twice. Both the modem and router to get quite hot when used for extended periods of time.
I am convinced at this point that the router and the modem are "disagreeing" with each other or there is some sort of conflict in the settings. I have no idea what to do at this point. The AT&T techs aren't the most helpful. They usually just do some line tests and say it's all good then they leave. I would appreciate any and all help provided.
Thanks
