Send a PM to our ATT Community Manager about the outside wiring; until that gets fixed, nothing you do inside will be a fix.

Mine does the same, mine is the problem with the outside wiring on the telephone poles. I had a tech come to my house on Saturday to verify this. At least 6 splices to the main telephone line cable. When it rains it is worse. They are not going to rewire the street hopefully can fix the mess out there.
My BIG problem is the Motorola modem that redirects me to their diagnostic site on all my webpages. I have to constantly unplug the Modem to "cash" it out. Do a internet clean up, clearing out all browsing history, cookies, ect. Reboot the computer. And then it will do it again and again and again. Until Motorola finds a way to climb the outside poles to correct this problem the diagnostic tool is an inconvenient "virus" to my system. ATT must work on disabling this re-direction to this worthless website.
I called the Technicians they are no any help. I seriously think I need another type of modem in this situation…Any suggestions.
I guess it's my turn. 
After two months of good service, I'm now starting to get drops in connection for one to two minutes. This might have been going on longer, as when I asked my wife she said it happened a lot, but she never bothered to tell me. These interruptions were about every four hours, I guess. However, they seem to have been picking up to the point we can't trust our internet connection and we're using our cell phones rather than the home line.
The house is 30 years old and when the techs installed our stuff, it took three trucks of guys half a day.
My screencaps: 
Much thanks in advance. I'm so happy I found this thread. And thanks to the man who wrote the diagnostic.

The "cable box" reciever is plugged into an ethernet/cat5 cable.
We are having that, wireless, phone, and wifi go out. Today it was for over an hour until I reset the modem/router.
Edited to add: I wrote my original post pretty poorly as I was being talked to at the time. These dropouts have only been going on for a few weeks. Generally they are one to two minutes in length but last night and today they have gotten much longer.
Also, the error page from nearly an hour after that first one, if that helps:
Thanks again.

You're where I was for a while, and I got fed up with RG resets and losing all services. You may need to get your RG replaced, and their remote tests may not necessarily recommend that.

Hope that works for you as it did here! TS started to argue, but when they saw I had the same RG since 2007... 
Make sure you get the old RG returned to a qualifying UPS Store ASAP, and get a receipt from the UPS Store. They'll pack everything and scan it for you (in case you haven't been through a return before).
Good luck!
Hi,
I owned AT&T Uverse service for about 2 months, it was good in th beginning but starting from last week, it keeps dropping signal but i am not sure about if that's my router.
I download the testing tool, could anyone help me to verify? It's really annoying, the signal drops few times while i am trying to read articles about this online...
The power level has absolutely nothing to do with it. Your power levels are well within spec.
The problem is that you are the proud owner of the worst looking Bitloading graph ever posted to the Internet. 
The nulls in your bitloading graph are caused by bridge taps. A bridge tap is an extra length of wire attached to your pair that doesn't terminate anywhere. It is usually left over from a previous customer that used your pair, or sometimes because of particular wiring schemes used in your home. Bridge taps cause problems with xDSL services.
You should call technical support, have them send a premises tech to your house to check the line. He should open a helper ticket with the Installation and Maintenance group (I&M), which are the linesmen, to come find and remove the bridge tap(s).
Also, what could also possibly help is a home run from the NID directly to your modem. The premises technician can install this when he comes.
