The router made with Broadcom 47xx card usually run a 2.4 kenrel with a Proprietary kernel module and a proprietary firmware for the wifi driver by default. But

  • the 2.6 kernel has support for the bcm47xx in 2 drivers:
    • b43
    • b43-legacy for older cards.
  • there is a free firmware called openfwwf for some broadcom cards
  • openwrt build system supports both(the free firmware and the free driver)

So all what we have to do is to:

  • build a rootfs with support for both
  • customize our rootfs to make it act like a router(the init scripts etc...)
