wireless not detected

Irenge · 2011-12-15 15:49:37

got a strange problem , after a fresh installation, wireless is not detected but when i put this command
/sbin/ifconfig wlan0 up
it indicates
wlan0: unknown interface: No such device
And when i issue ls -1 /etc/modprobe.d/
it indicates
blacklist.conf
dist-alsa.conf
dist.conf
dist-oss.conf
openfwwf.conf
Can anyone help me to solve this problem please ?

I'm still learning all the wonders of arch myself, but from what I understand wireless is generally (or at least often) not ready on a fresh install.

I've installed arch on a variety of machines and in each case once the basic install is done I need to hook up to wired ethernet to install the appropriate packages for wireless.

The 'appropriate packages' will depend on your wireless card.

Also, I'm not sure what all those modprobe conf files are. As far as I know on a fresh install there should only be one modprobe.conf.

Post the output of "lspci -nn" so I can check for sure, but I think all you need to do it install b43-firmware from AUR.

down is the oputput of lspci-nn . Hope u can help me

Now I know for sure which card you have. My previous suggestion was wrong*, what you need to do is blacklist bcma and then reboot. If it still doesn't work, post the output of dmesg. But use Code tags for it (click on the BBCode link to learn how to do that)!

* see kids, that's why you always ask for lscpi -nn, because it's the pci-id that matters, the name can be misleading (in this case it's wrong, the pciid database will need to be corrected)

by blacklisting bcma , u mean removing it?

Trilby · 2011-12-17 16:52:02

Irenge,

Have you read this wiki:
https://wiki.archlinux.org/index.php/Broadcom_wireless

I have the same wireless card on one of my computers. You should need the brcmsmac module. You will need to blacklist bcma and quite likely b43 and ssb.

Follow the instructions in the wiki. I just checked and either I'm having issues or the link to the blacklisting wiki in the broadcom wiki is broken. See here for blacklisting:
