Broadcom Corporation BCM4313 A WLAN não funciona no Arch instalado

Question

Eu tenho um controlador de WLAN Broadcom Corporation BCM4313 no meu netbook. Quando eu inicializo o ISO do Arch live e configuro a rede com o wpa_supplicant, tudo funciona bem. No Arch instalado, recebo o seguinte erro:

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

Não consigo entender por que ele não está funcionando, pois o driver brcmscmac faz parte do kernel e funciona perfeitamente na ISO ao vivo.

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

Tentar configurar o wlp2s0 apresenta o mesmo erro:

ip link set up wlp2s0

O módulo deve ser carregado (brcmsmac para a placa pci):

Agradecemos antecipadamente por todas as sugestões.

De acordo com o ArchWiki , você deve colocar o módulo b43 na lista negra porque ele entra em conflito com brcmsmac .
