The reality is the AT&T U-verse gateway and home network cannot provide consistent speed and service to the wireless computers on the network - even if a wireless computer is located within 10-12 feet of the gateway. 

Note here that I work from home and therefore am potentially less inconvenienced by numerous, lengthy service calls.  If you need to leave your home to work, you should think 10 times more about whether or not you want to schedule off work to be at home (it is required that an adult be at home while AT&T experiments to get their service running, even if it just runs badly)

AT&T will, or at least should, tell you the initial installation will take up to 8 hours.  They aren't kidding.  Our initial install was 7 hours and they were unable to hook up our primary television set so I scheduled a future date to install the last TV. 

What they don't tell you is it could take many service calls and many hours to complete the installation in a satisfactory manner all while suffering through sub-standard internet service from AT&T.

I immediately noticed the dial-up level internet speed while the installation tech was still at our home.  I mentioned it and he shrugged.  I then assumed it was a temporary glitch they would repair.

You know what happens when you assume . . . .

The installation took several more service calls to our home (I spent a lot of time home-bound waiting for and monitoring technicians) over the next two weeks.  Additionally, the internet refused to work with our X-Box, caused tremendous lags and frequent disconnects in World of Warcraft (WoW), and made surfing the web and/or reading e-mail unbearable.  

Needless to say, but,  I became a very, very unpopular family member!  Everyone was upset -  couldn't IM, couldn't e-mail, couldn't surf, couldn't play games.   They just kept asking me, "Why did you change??  Everything was fine!"

A consumer report and review of AT&T U-verse gateway wireless home network warning consumers that wireless internet speeds may be far less than advertised. AT&T wireless internet speeds may be highly inconsistent. Signal strength will show as 'excellent' but webpages will load very, very slowly. Much slower than cable internet for wireless.
