I've installed ubuntu 11.10 on my laptop (Compaq Presario V6000), which has BCM4311 Wireless Adapter, on the installation screen, it was showing
firmware not ready in the network menu, but when I installed with
install third-party software, the
Enable Wireless option completely disappeared in the menu.
I am using Wireless Ad-hoc to share my PC's connection, because my ISP doesn't allow more than one computer. So I can't connect via ethernet to download system updates.
