Open a terminal and type "lspci" to see if Linux detects your wireless card. If it does, then copy the name of it. Boot into an OS that has Internet, and research your wireless card. Figure out if Xubuntu supports it. If it does, there should be instructions on the official website (or Ubuntu's; they should be the same). With my wireless card, all I have to do is go into the Hardware Manager and click 'Activate' to activate my wireless card.
