Broadcom 4311 wireless not working

Asked by Steven Mitnick on 2008-02-03

I have a laptop Compaq F572 using the wireless card Broadcom 4311 Rev 2 and I have not been able to get it to work using 7.10 and the 8.04 alpha's. The Network Settings on the 8.04 shows Wired Connection and Point-To-Point Connection, but does not show Wireless Connection. All three were visible on the 7.10 version, and the wireless connection worked with 7.04. The restricted drivers used to automatically appear for the video card and the wireless card, but with 8.04 Alpha 4 the wireless firmware does not even appear. I have tried the instructions on the 7.10 and 8.04 alpha versions at: without success. I even modified the driver using: located at:

It seems that with each Ubuntu version the chance to connect this computer wirelessly is getting less likely. Does anyone have any better ideas?

In 8.04 it should work with bcm43xx-fwcutter (use Restricted Manager - System→Administration→Restricted Driver Manager) to use it.
