Problems with ATT Uverse and Ubuntu

I recently switched from Time Warner Cable to ATT U-verse. I'm very happy with the picture quality on my TV but the Internet connection on my Ubuntu 10.10 system was very slow even though speed tests said I was getting the band width I paid for. The problem turned out to be the DNS. For whatever reason the DNS lookup was very slow using the new service. I switched to Google public DNS and everything worked fine.

To fix the problem I went to System->Preferences->Network Connections and selected Auto eth0 from the list and then the Edit button.  A window will pop up wiht 4 tabs. Select the IPv4 Settings tab. A drop down list will show Automatic DHCP. Change the drop down to Automatic (DHCP) addresses only and add your favorite DNS addresses to DNS Servers. I used 8.8.8.8, 8.8.4.4 for the addresses.

Your final window should look something like this.


This fixed my problem instantly.
