Hello imwilliam, welcome to LQ,

could you please open a terminal and post the output of the commands
Code:
iwconfig
and
Code:
lspci -k | grep iA5 wireless
Do you know which encryption your wireless network uses? Are you using DHCP? Please provide more information.

Markus

Well, at least there is no wireless adapter recognized by Linux. Could you please post the whole output of
Code:
lspci -k
You'll probably have to install the Broadcom-driver from the repository of your distribution.

You have a Broadcom-adapter (as you already mentioned) with 4331 Chipset, it seems to be difficult to find the appropriate Linux-driver for this device. I've found nothing on the Broadcom-site. Look at the repository of your distribution and if there is nothing maybe you'll have to use ndiswrapper (which makes a Windowsdriver available under Linux) but I didn't find a Windows-driver as well.

Well, which distribution are you using? Ubuntu as you mentioned? well, then read the documentation about the package manager: https://help.ubuntu.com/community/SynapticHowto and find out if there is a driver for your wireless adapter and how to install it.

There is much documentation about Ubuntu in the internet, just search and read.

Good luck

Markus
