Just installed Ubuntu 12.04 on a Dell Inspiron 8500. It has no wireless hardware. lspci tells me the ethernet controller is bcm4401. Because I have no driver, the box is mute and without an internet connection. On another computer, I downloaded what I believe to be the correct linux driver from the Broadcom site. Unfortunately, it's a tar.gz file. I have followed the instructions to the letter six times yesterday and six times today without being able to install the driver. The driver package also contains an rpm but I have no idea how to install that. So, I need a debian/ubuntu installer for the bcm4401 driver that I can download to usb and move to the mute box. Any idea where I can get that or what I should do? I googled other distros that come with broadcom drivers and have downloaded a couple but haven't tried those yet because I would prefer unbuntu on this box. It runs well and fast and the graphics are great. Any help?
