I have successfully installed my drivers and can detect wlan0 using the b43-firmware.
I cannot seem to be able to use this NIC at all
if I use wicd or network manager, Opera freezes, ifconfig doesn't work and the system cannot reboot(and I cant use wireless), if I use rfkill to disable wlan0, wicd/network manager work just fine till i reenable wlan0.
ifconfig wlan0 up yields the same result.
I'm using 09:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)

here's my kernel config: http://pastebin.com/b9cR2qwN



thanks

I unmerged b43 firmware and installed linux-firmware instead, then I brought up the interface(ifup wlan0) and everything is working now

I have a 4306, a little older than yours, but using network manager never works correctly for me. At times its spotty, and therefore, I only use iwconfig and openrc

thanks for the reply first of all

iwconfig yields the same result, anything that has to do with wireless simply screws things up
ill try using openrc bt i imagine I'll be getting the same result

gentoo-pc ~ # iwconfig

a simple ifup brought up the interface and everything is working now

I'll try broadcom-sta later for the LED functionality but for now I'll be enjoying my wifi at last

thanks everyone

iwconfig requires wext compiled into the kernel... what driver did you get working?

I think I might have enabled wext at some point when I was messing around with my kernel config
I got the brmsmac module working
