I've got a pluscom pci card plugged into my desktop and although the mac address shows up in network manager, it says "Wireless unavailable".

I'm using Ubuntu 12.10 Gnome Shell Remix...

edgar@edgarQuantal:~$ iwconfig
eth0      no wireless extensions.

lo        no wireless extensions.

It looks the same as the problem as here, seems quite complicated: http://ubuntuforums.org/showthread.php?t=1993226

Tried downloading the driver but i get this:

"Unpacking firmware-ralink (from .../firmware-ralink_0.36_all.deb) ... dpkg: error processing /home/edgar/Downloads/firmware-ralink_0.36_all.deb (--install): trying to overwrite '/lib/firmware/rt2870.bin', which is also in package linux-firmware 1.95"
