U just got an old Dell OPtiplex GX240, with broken LAN port, so I thought about buying an USB Wi-Fi adapter, problem is USB port 1.1 version.. Will it work?!
Some do, there are good models by Trendnet and Netgear that I've used. Just search google for "usb 1.1 wireless adapter" and look for one of those models on Newegg or Amazon.
