I just installed 11.04 on my laptop and the wireless works fine connecting to a AT&T 2Wire router when the ac power adapter is connected. When running on battery power I stay connected to the router but barely any information is transmitted. ie. if i restart the router connection on my computer I can load a web page like google.com then nothing else will work unless I restart the connection again. If I am right next to the router it will continue to work but very slow ( takes about a minute to load youtube.com when it only takes 2 seconds on ac power ). When I run windows 7 everything works fine when on battery power.

Also every thing works fine on a linksys router with ac and battery power.

Dell Inspiron 14R
Processor: i5-2400M
Wireless Card: Intel Centrino Wireless-N 1030
Ubuntu 11.04 Natty Narwhal
