I have the following wireless adapter:

Code:

44:00.0 Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01)


I still have a 3.2.22 kernel because broadcom-sta does not work on higher versions. However, I would really like to use kernel 3.6.9 (and higher as things go forward).

I have just spent an entire day trying to figure this out. I have read this (including the bug linked from that page), this and this, and I am still at a loss.

Am I able to use this wireless adapter on higher kernel versions, and if so, exactly what do I need to do? This has been extremely frustrating, and I'd greatly appreciate any help I can get.

Two options:

a) Activate brcmsmac in the kernel as module. Install linux-firmware.

b) Activate b43 in the kernel as module, also activate B43_BCMA and B43_BCMA_EXTRA and support for N-PHY. Install b43-firmware.

Neither of those options worked. I can't figure out if my wireless simply will not work with higher kernel versions or if I'm missing a step. I really hope it's the latter.

For option "a", I:


  • blacklisted wl (otherwise it will cause a kernel crash with these options)
  • cd /usr/src/linux (which points to my installed 3.6.9 sources)
  • make menuconfig
  • Activated brcmsmac in the kernel as a module
  • Exited out of menuconfig
  • make && make modules_install
  • Copied kernel image to boot partition
  • Listed kernel modules in /etc/conf.d/modules
  • emerge linux-firmware
  • Rebooted


The card is not detected and not activated. The laptop has an LED for the card: orange when inactive, blue when active. The LED remained orange.

I should note that I already had b43-firmware and b43-fwcutter emerged from previous attempts to get this working. Would that cause a conflict?

For option "b", I:


  • blacklisted wl (otherwise it will cause a kernel crash with these kernel options)
  • cd /usr/src/linux (which points to my installed 3.6.9 sources)
  • make menuconfig
  • Undid the options from "a", above
  • Activated b43, B43_BCMA, B43_BCMA_EXTRA, and b43_n_phy (however the symbol is correctly spelled) as modules
  • Exited out of menuconfig
  • make && make modules_install
  • Copied kernel image to boot partition
  • Listed kernel modules in /etc/conf.d/modules
  • emerge b43-firmware (was already emerged, but did it again anyway)
  • Rebooted


Again, the card remained inactive. Also, linux-firmware was installed from having tried option "a". Would that create a conflict?

Am I screwed with this wireless chip or am I missing something?

I should note I use wicd and don't have wpa_supplicant emerged - does that matter? It doesn't with older kernels and broadcom-sta.
