I frequently get disconnected from U-verse internet. I have several computers connected, but this is the only one that disconnects randomly. I'm right by the modem, so it's not a signal strength issue. There are 3 Windows 7 laptops connected, and this is the only one that has the disconnection issue. I haven't changed any network settings since the AT&T technician hooked it up. What I have to do is click the connection icon, disconnect and reconnect. This happens every 20 minutes or so. Sometimes it will go for 2 or 3 hours, but that is rare. The other 2 Windows 7 laptops don't lose connection.
