I just re-flashed the E2000 back to stock Cisco firmware.

I then did a factory reset on the Uverse gear.

My only changes to the 2wire settings post reset were to:

-Enable ethernet port

-Enable DMZplus on the router MAC

My only changes to the E2000 were to:

-Change network address from 192.168.1.1 to 192.168.2.1

-Setup wireless

Same results on speed test....

Connected wirelessly to 2Wire 8 Mbps

Connected wirelessly to E2000 2.5 Mbps

Any ideas?
