http://ubuntuforums.org – I am running Ubuntu 10.10 maverick netbook edition on my Dell Latitude D830. I am dual booting windows 7 and ubuntu and recently I bought a Cisco Linksys E2000 router. I set it up with a WPA/WPA2 mixed mode security and My friends are all able to connect to it with no problems. I've been running Ubuntu for a while now and i've never had wireless problems until now.
