Linux n00b here, just installed the latest Unbuntu, got a few Q's

[refresh]

My card is a Belkin F5D7000v1, and ubuntu does seem to detect it ok, but I haven't figured out how to get it to connect to a wireless network (yet).

From some googling I have done it seems that you have a Ralink RT2560 chipset in that card, however

lspci

should confirm this.

as long as you don't have Fiesty Fawn and it is the ralink chipset this should help:

If you have the broadcom chipset try:

please let us know how you get on.
