http://crunchbanglinux.org – Hi,I recently came to #!. Because i was using ethernet all the time i didnt check if i can get my wireless working. So today i saw that I can't even see possible connections. My wireless settings are completely gone..My "iwconfig output is:pan0 no wireless extensions. eth0 no wireless extensions. lo no wireless extensions.I already googled the problem but all the topics i found had at least an output of their wireless adapter. I have no idea what i should do now! Anybody got an idea? (HowTos)
