Hello!
I have dell xps-m1330 laptop with BCM4312 wireless card on board. Here is the output of lspci command:
$ lspci -nvv | grep 14e4
09:00.0 Ethernet controller [0200]: Broadcom Corporation NetLink BCM5906M Fast Ethernet PCI Express [14e4:1713] (rev 02)
0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
I have installed b43 driver folowing instructions on wiki page for my laptop, which redirects to broadcom wireless wiki. I have installed b43-fwcutter from repo and b43-firmware from AUR.
After reboot, b43 kernel module seems to be loaded:
$ lsmod | grep b43
b43 362413 0
bcma 28684 1 b43
mac80211 432338 1 b43
cfg80211 179435 2 b43,mac80211
ssb 51756 1 b43
pcmcia 46261 2 b43,ssb
mmc_core 90305 4 b43,ssb,sdhci,sdhci_pci
but there isn't any wireless interface:
$ iwconfig
lo no wireless extensions.
enp9s0 no wireless extensions.
$ ip addr

Here is the output from dmesg:
$ dmesg | grep b43

I would appreciate any help on getting wireless interface up. Sorry for my English.

I have forgot to specify my kernel version. It is 3.7.8-1, x86_64.

That error message is couldn't be clearer - firmware isn't there. You said you installed b43-firmware, but apparently you didn't. Make sure the firmware is installed properly.

Thanks for the fast response!
I've got it working now. Seems like I forgot to run "pacman -U ..." after makepkg
