Hi all,
my wireless network interface is not working after system
reinstallation. Before it was working perfectly. It cannot get an IP
address from DHCP. Also, when I assign to it and IP address manualy,
it's not working. The wired interface is working perfectly. Itried
with both ordinary and backported versons of the driver available in
Debian repos (broadcom-sta-dkms).
I hope someone will have an idea on what's going on.
