Cannot connect with Netgear WG111 v2

Hi, I wanted to reinstall Netgear WG111 v2, (it was running slowly and I thought maybe uninstalling and reinstalling would help. I insert the CD and everything OK, even at the end says everything has been installed and to plug in the adapter. When I do , absolutely nothing happens (Found new hardware should have come up) I try to install new hardware manually but I get a message saying the drivers are not installed. Tried getting the latest drivers on another computer on disc and install them, still nothing,

Any ideas? I have been trying everything for days now!!!!
