I was pleasantly surprised recently when I installed Xubuntu 10.10 on an
HP PC. I had attached a Linksys WUSB100 USB Wireless adapter before
when it was running XP.
It automatically installed driver for it and usually comes up connecting
to my D-Link Wireless N router at 130 to 150 Mbs. It could not have
been easier and it connects
at a high data rate.
