[Solved] Yet Another Broadcom Wifi Problem After Kernel Upgrade.
I have:
04:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
Subsystem: Broadcom Corporation Device [14e4:04b5]
07:00.0 Ethernet controller [0200]: Broadcom Corporation NetLink BCM5906M Fast Ethernet PCI Express [14e4:1713] (rev 02)
which worked fine until the recent kernel upgrade. Now it doesn't appear to be detected at all. I have:
blacklisted bcma - didn't work
Un-blacklisted bcma and then blacklisted brcmsmac. Installed b43-firmware from AUR. That didn't work either. Now I am stuck!

Are you sure you used b43 before? If you by any chance used broadcom-wl from AUR, you need to rebuild it after the kernel update.

Does it only break your wireless or Ethernet as well?

Re: [Solved] Yet Another Broadcom Wifi Problem After Kernel Upgrade.
I didn't specifically load any drivers before, it "Just worked" Ethernet is working fine. No messages about broadcomm in dmesg or boot, sio it looks as though the kernel doesn't detect the chip.

OK, I tried installing the broadcom-wl driver, despite all the warnings:) So far this seems to be working OK.

Good!
Broadcom is shit. I wish I'd know this before I bought my laptop. I'm stuck with wl as well :-(
Don't forget to obtain the latest broadcom-wl from AUR just before you pacman -Syyu, and rebuild it again after - kernel upgrades break it. (If there already exists some convenient way to automate this, I'm all ears.)
