I was wondering if drivers are available for the Linksys WMP300n wireless network card for Ubuntu? Any help would be greatly appreciated.
Please open a terminal and run:
lspci -nn | grep 0280
Is your device this?
14E4:4329 If so, it is a Broadcom wireless device. Please open Software and Updates and make sure that main, universe, restricted and multiverse are enabled. A window will open asking you to reload; accept and continue.
With a temporary working internet connection, open a terminal and do:
sudo apt-get install bcmwl-kernel-source sudo modprobe wl
Your wireless should be working.
If your device ID is different, edit your question to include it and I will propose a solution.
