Soporte Wifi BCM4313 [14e4:4727] en linux 3.6

Llevaba dándole vueltas para conseguir activar el soporte para la tarjeta wifi dando palos de ciego, pero el camino bueno es este :

http://linuxwireless.org/en/users/Drivers/brcm80211

usando make menuconfig activamos las siguientes opciones del kernel

Location: -> Device Drivers

• -> Network device support
  • -> Wireless LAN
    • -> < m> Broadcom IEEE802.11n PCIe SoftMAC WLAN driver
    • -> < m> Broadcom IEEE802.11n embedded FullMAC WLAN driver
      • -> [*] SDIO bus interface support for FullMAC driver
      • -> [*] USB bus interface support for FullMAC driver

For the PCIe SoftMAC WLAN driver (brcmsmac) you need to enable select the BCMA bus driver as well:

Location: -> Device Drivers

-> Broadcom specific AMBA

-> <M> BCMA support

-> [*] Support for BCMA on PCI-host bus

recompilar , instalar el kernel nuevo y a correr
