It might be useful to tell us exactly what unit this is. In Accessories/terminal
run the command: lspci
Then cope/paste the line which includes "802"
(That assumes the wireless adapter is a PCI device. If it's USB, use lsusb.)

Some wireless adapters have changed drastically from ver 2 to ver 3, for
example, and even though the packaging is the same, getting them working is
completely different.
