I bought something like 2 2 packs of the USB version of these when Office Depot was clearing them out for like $15 each (2 pack) and after (attmpting to) install them, on two seperate machines (one win2k pro, one win2k server, with a clean windows install no less) and having them BOTH BSOD on boot after the install of these, requiring a reinstallation of windows, I would say pass. I tried with both the drivers on the CD and the drivers on the website (were SUPPOSED to support windows 2000) I never did get one to work. Needless to say, they broke 2 out of 2 machines, so while there were a nice idea, off to e-Bay they went (and sold for more than I paid

I ended up with a Linksys WAP11 and a Xircom 128bit 802.11b card, works well.
My advise: Avoid these. One of these will NEVER get plugged into one of my systems again. Also, they are not 802.11b, they are proipritary, and if I remember correctly, rather slow (1mbit/second?)
