http://askubuntu.com – I downloaded Ubuntu 11.10 on my laptop and the WiFi light will not come on. It was working when I was using Ubuntu 10.03. My laptop has a Broadcom BCM 4311 802.11 b/g wlan card. I tried everything I could find and nothing works. If it helps, I am not a programmer. I'm just a novice. (HowTos)
