brcm80211 is a completely FOSS wireless driver for BCM4313, BCM43224, BCM43225 chipsets.


  • Completely open source host driver, no binary object files
  • Features Broadcom's OneDriver architecture (single source base for supported chips and architectures)

  • On-chip firmware loaded using standard request_firmware()
  • Support for BCM43224, BCM43225, BCM4313 (PCIe NIC)
  • Framework for supporting new chips, including mac80211-aware embedded chips
  • Does not support older PCI/PCIe chips with SSB backplane
  • Driver includes BMAC interface for transparent dongle support
  • Uses minstrel_ht rate algorithm
  • HW based encryption not enabled yet

Whats Done

  • STA mode (in infrastructur
  • N phy code for 43224/43225
  • LCN phy code for 4313
  • Infrastructure for future phys.
  • AMPDU support
  • 4313 is stable
  • many software, ucode and phy/radio counters available.

To Be Done

  • 43224/5 has a locking issue, stable with maxcpus=1, can crash otherwise after random period.
  • Only minimal mac80211 interface is implemented, Callbacks need to be filled in more.
  • Code needs to be optimized for linux:
    • wl_xxx vs wlc_xxx separation needs to be collapsed and eliminated
    • private utility routines and headers need to be replaced with standard kernel routines and headers.
  • Add support for
    • suspend/resume
    • RFKill
    • 40MHz channels
    • powersave
    • debufs (for accessing counters and other diagnostic info)
    • monitor mode
    • IBSS
    • AP
