My laptop was running 8.04 LTS (hardy), using network manager I believe, and the wireless worked fine. I do not believe I was using ndiswrapper, as the original version of Ubuntu I installed (edgy) just auto-detected everything. I did an upgrade to 10.04.3 LTS (lucid) and when I rebooted wireless networking stopped working. I can't even get it to connect to open wi-fi.
