Can see network but can't connect with Netgear Wg111v2

Hi!
I've been looking around the forum but can't find anything like this.
I had been using a Netgear Wg111v2 wireless USB adapter for the last 2 weeks and it had been working fine. But suddenly the computer lost it's connection while surfing the web and I can't get it to reconnect... I've rebooted everything at least twice to no avail and all the other pc's connected to the network work fine... can anyone give me suggestions?

Hi there, are the other computers connected with wireless as well? if so can you try one of their Wifi adaptors. If this is the only one then you may want to delete the wireless profile stored in the computer for this conenction and try and connect with no securtiy set on the AP. You could also try the failed adaptor on another PC to ptove it is not faulty. Cheers, Dale
