The Belkin wireless USB dongle works fine on my daughters USB 1 port on her laptop. It comes with it's own drivers and works fine on Windows 2000 according to

Also, as per an Intel FAQ, "USB 2.0 will be 480 Mb/sec, 40 times faster than USB 1.1" which makes USB 1.1 about 4Mbit/sec. Much faster than most broadband connections (in UK any way) these days so it will be fine, unless you are wanting to tranfer very large files all the time.
