BROADCOM BCM4306 802.11b/g
UBUNTU 9.10 +proposed
My wifi has been working months and months, but just stopped.
* I think I unchecked Enable Wireless from the Gnome Panel Network Manager drop-down.* [it is a known problem up to Ubuntu 9.10 that once the Enable Wireless is disabled either manually or by hibernate/sleep system modes, that it can not be re-enabled during the same session until the system has been restarted]
* Restarted the system, it started asking for my wifi passphrase (which is still stored) and eventually it didn't see any local APs at all (of which there are many).* The pull down says the BROADCOM is Disconnected (not disabled).
* A borrowed USB wifi stick (RALINK 802.11 BG WLAN) which worked and used the stored AP passphrase.
* Checked the Hardware Drivers which showed BROADCOM B43 WIRELESS DRIVER as Active.* Removed/reinstalled it again as Active.
* The Power Management field from iwconfig says off, and maybe should say 'managed'.* I tried 'iwconfig wlan0 up', but that is an unrecognized command/feature.
* I noticed when I used the borrowed USB wifi stick, the Network Manager does not ask for my admin password as it did for the built-in wifi.* I just used the stored AP passphrase and connects.
