the described method to get the wifi working under debian wheezy (broadcom bcm43xx) in the debian wiki ( http://wiki.debian.org/wl#Wheezy ) worked for me....yesterday.
after rebooting the computer ( lenovo ideapad s10 netbook ) there is no eth1 available anymore. unloading possibly loaded wrong drivers with modprobe and reloading the broadcom drivers ( modprobe wl ) didn't help. neither did doing all the in the debian wiki described steps again.
before you ask: yes, the wlan module is on and recognized ( lspci ).
please help me!
