What driver are you running? Brcmsmac/Brcmfmac?
The errors seem as if you do need to install a missing driver. You'll have to download and install the correct drivers and modprobe it into your kernel, possibly blacklisting Brcmsmac and some other related modules.

Also check this for more help on it. https://wiki.archlinux.org/index.php/Broadcom_wireless

The error message couldn't be clearer: "YOUR FIRMWARE IS TOO NEW [...] You have to install older firmware or upgrade kernel."

Trilby · 2011-12-27 13:17:35

I also think the error message is clear - but suspect the relevant point is earlier: " b43-phy0 ERROR". B43 shouldn't be giving errors as it shouldn't be running. You should use brcmsmac with that card.

Can you post (in [ code ] ... [ /code ] tags) the output of lsmod.

Actually, no. Both drivers, b43 and brcmsmac, support this card.

I get this if I'm not root.
As root, does "iwlist scan" help?

I just went with listings on the wiki. I'm happy to be corrected and learn from it. In either case I wanted to ensure that there weren't competing modules loaded, which doesn't seem to be the case.

jewnersey · 2011-12-29 19:36:09

im having this very same problem, with the same hardware BCM43225
any resolution here?

jewnersey · 2011-12-29 20:06:45

solved my problem. deleted everything. blacklisted bcma and b43legacy. installed fwcutter from pacman. installed b43-firmware 5.10.56.27.3. had to force and overwrite some files. modprobed b43 then ip link set wlan0 up worked no error. dmesg still gives me some BS about b43-phy0 but im connected after doing the wpa_supplicant -B -Dwext.... in the beginners wiki and then running dhcpcd

CarlosFraire · 2011-12-30 03:11:05

[carlos@Archlinux ~]$ ip link set wlan0 up
Cannot find device "wlan0"

can you tellme how I deleate everything to begin from the first? sorry for my ignorancy

CarlosFraire · 2011-12-30 03:25:38

haha solved...
Tengo una Broadcom:
12:00.0 Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01)
Antes usaba el módulo brcm80211, leyendo me entero que fue renombrado a brcmsmac, ejecutando un lsmod me doy cuenta de que ya está cargado el módulo pero sigo sin ver mi tarjeta inalámbrica.
El problema es de que el módulo brcmsmac tiene conflictos con el módulo bcma, así que la solución es ponerlo en lista negra en el archivo /etc/modprobe.d/modprobe.conf para que no cargue al iniciar el sistema:
blacklist bcma

I have a Broadcom:
12:00.0 Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01)
Before using the module brcm80211, I find that reading was renamed brcmsmac, running a lsmod I realize that is already loaded the module but I still see my wireless card.
The problem is that the module brcmsmac conflicts with the bcm module, so the solution is to get it blacklisted in / etc / modprobe.d / modprobe.conf not to load at system startup:
bcma blacklist
