On newly purchases Dell Vostro 1520, I installed Ubuntu 9.10, and
found WiFi card problem.

"Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)"

On searching Internet, got:

http://jomcode.com/fadhil/?p=59 , I was able to make WiFi to work in first go.

But next day, when I started laptop, it was again not working. On
"modprobe wl", it does not work.

dmesg's output is:

[ 631.098107] lib80211: common routines for IEEE802.11 drivers
[ 631.098113] lib80211_crypt: registered algorithm 'NULL'
[ 631.143473] wl: module license 'unspecified' taints kernel.
[ 631.143480] Disabling lock debugging due to kernel taint

Please help me. What I can do.

https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx and
http://linuxwireless.org/en/users/Drivers/b43#Known_PCI_devices might
help. Especially note that you need to download firmware for your
broadcom chip!

Good luck!
