Ubuntu

How do I enable wireless controller?

Asked by Spedward

After I check for the driver and then check to see if my device is on with 'sudo lshw -C network' it tells me that my wireless device is disabled. I looked around a little and read some posts and then entered 'lspci' to see what my device was and it says

Network controller: Broadcom Corporation BCM94311MCG wlan mini-PCI (rev 01)

Could someone please help me out?
Im running the new version of ubuntu (7.1) from a livecd

Thanks in advance :)

Used the same guide and it worked for two different laptops running identical wireless cards. Once on a Compaq Presario C715NR, and a second time on a Gateway MX6447. The default Broadcomm firmware cutter shipped with Ubuntu 7.10 didn't do the job. Pasting a text version of the web page here in case something happens to the wordpress.com article. You have to provide your own firmware from your windows installation disks.

Major kudos to invaleed for a well put together article.
