Often it's all about hidden SSIDs, using WEP or less security. The Cnet Networking forum has suggested settings but how to see if that's it or if this is it or another failure?
My son's Dell Inspiron Mini runs Windows XP SP3, and refuses to retain the settings for our wireless hub. It goes through the motions of connecting and then drops the connection straight away.
Does anyone have any suggestions? I've tried removing software and switching off the firewall, but nothing seems to work.
