In Hardware drivers list, It shows Broadcom 45 driver. But no wireless in NetworkMAnager. Even i tried ifconfig, There is no wlan0. Earlier it used to detect. After some kernel update or something this started. Don't know when. I also tried removing and adding driver again with synaptic.

Ubuntu 9.10

Please help. How to check why hardware is missing ? In bios i don't see any settings for wlan. Some one told me to restore default in bios...didn't work.
