So I recently did a fresh install of Ubuntu 11.04 64-bit, an upgrade from 10.10 64-bit. My wi-fi card used the isl3887usb and isl3887usb_bare firmwares, which I have put into the /lib/firmware directory, same as I did on 10.10. The networking center recognizes my wi-fi card after rebooting the system, but it will not recognize any networks, even though my 10.10 system did at the same exact spot. Any ideas what the issue might be and how I can fix it?
