I was trying to follow instructions provided in this question AFAIU bcmwl-kernel-source is a proper driver for me. But after installation nothing changed. By "nothing changed" I mean iwconfig shows only eth0 and l0 with no wireless extensions, rfkill list all contains hci0: Bluetooth.
I found that bcm43xx was blacklisted in /etc/modprobe.d/blacklist.conf, after commenting this line and removing previously installed driver I repeated the same actions. The result was the same.
The line above the bcm43xx in /etc/modprobe.d/blacklist.conf file says "replaced by b43 and ssb". So I have removed previously installed driver again and edited back blacklist.conf.
I installed firmware-b43-installer, b43 was listed in the lsmod, but I am still was not be able to see any wlan in iwconfig.
Any help will be highly appreciated.
