Broadcom Wireless not working

Hi All

I am new to arch linux. I have a dell studio 1535. My wireless card is Broadcom BCM4312. As the wiki page suggested, I installed the broadcom-wl driver. The wiki says that b43 and ssb need to be blacklisted and i did that too. Also, my interfaces were swapped by the driver and i restored them as mentioned. The following is the output when i try to connect to a wifi network whose essid is Kaushik and wep-hex key is 7204066967.

sudo ip addr

Finally, It doesn't connect to the network. Wired network works beautifully. Any idea as to what is the issue? Thanks a TON!

The most direct answer would be to try disabling IPv6. There is a good wiki page on this - it involves adding a parameter to your kernel line in grub's menu.lst.

But also, if you haven't already done so, you may want to also try the b43 driver. As far as I know - which may not be very far, admittedly - there have been some improvements since the wiki page was written. Many cards that used to require wl are now covered by b43 or brcmsmac.

YES! It worked. Is there a way that this information can be updated in the arch wiki for future benefit?

It is a wiki, it's readily editable. I'd just suggest assessing to what degree your experience may be generalizable to others - but if done well, by all means edit.

Out of curiosity, did disabling IPv6 do it, or did b43 work for you?

b43 worked for me.
