I have Windows installed on my Acer Laptop and recently installed Ubuntu (using their installer for Windows) so there are now 2 OS's installed. Ubuntu was unable to connect to the Wifi, so I can only get internet on it when plugged in.
The Laptop is an Acer Extensa 4420, and the network adapter is Broadcom 802.11g. Windows lists its drivers as BCMWL6.SYS and also 3 drivers called bcmihvsrv.dll or something similar.
How do I get wifi enabled on it?
