I have for sale a ZyDAS ZD1211 802.11 b+g USB WiFi adapter.
Has been tested working with:
Linux Mint 10
Vista Home Premium
works well with the above mention Linux distros - no drivers needed. Vista update will download the drivers for the adapter so needs a connection for that first.
Saw AberdeenDad was interested in one of these to work with UBUNTU so will let him know and give him first dibs
