I need help. After upgrading from Karmic to Lucid, no wireless networks are found on my computer—an acer travelmate 5510.
On Karmic, wifi worked flawlessly "out of the box"—no windows drivers or anything needed. I have checked under Administration/hardware drivers; it tells me "no proprietary drivers are in use on this system." Cabled internet access through my wifi router works fine.
I would really appreciate anyone who can help me get wifi up and running under Lucid. Despite having used Karmic for a while, I am relatively new to the inner workings of Ubuntu / linux systems, and really don't know where to go from here.
