I have a Broadcom Corporation BCM4313 WLAN Controller in my netbook. When I boot the Arch live ISO and set up the network with wpa_supplicant everything works fine. On the installed Arch I get the following Error:

wpa_supplicant -i wlp2s0 -D wext -c ../wpa_supplicant/wpa_supplicant.conf -B

brcmsmac bcma0:0: brcms_ops_bss_info_changed: qos enabled: false (implement)
brcmsmac bcma0:0: brcms_ops_config: change power-safe mode: false (implement)
IPv6: ADDRCONF(NETDEV_UP): wlp2s0: link is not ready

I can't figure out why it's not working as the brcmscmac driver is part of the kernel and works flawlessly on the live ISO.

Output of lspci:
02:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)

Output of ip link show:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT 
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

Trying to setup wlp2s0 gives the same error:

ip link set up wlp2s0

The module should be loaded (brcmsmac for the pci card):

Thanks in advance for all suggestions.

Are both the required modules loading? –  jasonwryan Oct 2 '13 at 17:18
    
I added the output of lsmod to the problem description –  Gerd Müller Oct 4 '13 at 8:28

Try blacklisting b43; it may be conflicting. –  jasonwryan Oct 4 '13 at 8:32
    
Tried it, same problem. Any other idea? –  Gerd Müller Oct 6 '13 at 22:10
    
used broadcom-wl instead. worked like a charm –  Gerd Müller Oct 14 '13 at 10:18

According to the ArchWiki, you must blacklist b43 module because it conflicts with brcmsmac.

It may also be worth mentioning @jasonwryan (who mentioned exactly this solution in-comments a while ago). –  HalosGhost Jun 25 at 4:34
