Ubuntu Networking :: Broadcom 4313 On HP Dm4 Not Finding Wireless Connection

My HP Pavilion dm4 notebook has the Broadcom bcm4313 and worked with the proprietary Broadcom driver provided with Ubuntu 10.04 but did not work with the corresponding driver provided with Ubuntu 10.10. The solution that worked for me (for a while) was to install "broadcom-sta-common" and its dependencies using Synaptic. After enabling the proprietary driver (System > Administration > Additional Drivers) and rebooting, wireless worked. I even shared this on this post. chargersfan420 get his Broadcom card functional again.

What changed to break it? Well, wireless had worked for several days, so I felt that I had solved the wireless problem. Now it was time to find a solution to unlock my BIOS settings. I successfully used PCCMOSCleaner to clear the password. After that, no more wireless. (Note to dm4 users: Apparently HP puts a password on the BIOS settings and makes it available only if you boot into the factory-installed Windows 7 and retrieve it. Of course I never booted into Windows 7 before upgrading the machine to Linux, deleting both the Windows partition and HP's hidden recovery partition.)

I uninstalled all the Broadcom stuff and reinstalled it all. Now I appear to have wl working, and b43 and ssb blacklisted, but network manager is not seeing any wireless connections available.

My Hardware: HP Pavilion dm4-1063cl My OS: Ubuntu 10.10 32-bit (clean install)
