This is just me sharing my experience with Uverse for the past two plus years.
45440 Zip Code
Configuration: AT&T Uverse
Motorola NVG589
Max+ internet
one wired DVR, two wireless (WAP) receivers
I found AT&T DNS sucks. If you don't believe me, change to google DNS (8.8.8.8) on one of your clients and test. However, with AT&T, they don't allow you to change the DNS at the router and I happen to favor OpenDNS.
Therefore, I shut down the NVG589 Wireless and configured an Apple APE (Airport Extreme) behind the device.
I also have an AppleTV, Visio SmartTV, couple iPhones, iPads, Alexa...you get the picture :-)
Oh yes, I also added a TP-Link system to link up my second Airport Extreme.
Now, before everyone begins ranting that I've made things rather complex, that having multiple APe's and everything is creating issues, I've done enough testing to determine the root cause of my issues; shared IP across internet, VoIP, HD TV, DVR, blah, blah
Turn off all AT&T receivers, I can squeak about 20 megabits/s down and 1.9 megabits/s up.
Activate a receiver and the downstream number immediately drops by 5 megabits/s
Run two concurrent, plus DVR and my downstream drops to between 6.8 and 5.8 megabits/s
I have disabled IPV6, to see if that helps, it doesn't
And, I have a really good connection from AT&T

Shut all network devices but the NVG589, enable the NVG wireless...same results.
Conclusion, for my location, sharing internet with VoIP and HDTV is just placing too much demand on the service. I do like the UVerse TV service, HD DVR, and WAP HD receivers...
Of course, as I could be missing something others may know...willing to listen.
