I've got a Dell precision with Kubuntu 9.10. Wifi worked fine on that machine for months, but stopped working last week. I don't know what happened, but I recently did an "apt-get dist-upgrade". That might have something to do with it.
Does anyone have any suggestions that might point me towards a solution?
When I boot in Windows, wifi works fine.
