http://crunchbanglinux.org – I have had Crunchbang Statler installed for a few weeks now, with wireless internet working out of the box without any problem (despite the wireless card on this laptop being an old Broadcom  BCM4309). However, today I turned on the laptop and it cannot find or connect to any wireless network. Running 'iwlist scanning' fails to find the wireless connection, and no matter where abouts I am, or how close to the router, the problem persists. At first I thought that the wireless card had somehow been turned off, but neither 'ifconfig wlan0 up', nor rebooting the computer, (HowTos)
