I did the same thing setting up Linux Mint 12 (ubuntu). It did find one additional, happened to be a proprietary driver. But installing it did not help to get my wifi working.
So after a little research on what commands to use for setting up a wireless network in linux:
- I used command $ lspci in terminal, wrote down my wifi card info.
- Matched the wireless NIC model number to an associated driver.
- Then located, downloaded, and installed the driver through synaptic package manager.
- I rebooted the machine and wireless worked.
Note: lspci=list all PCI devices, ifconfig works as well.
Hope this helps.
