I was given a used laptop from work and am having problems hooking it up to my home network. Works ok with ethernet cable but not wireless. It is a Dell WLAN card, I switched my netgear router to open network, just to try to hook up. The wireless utility says connected, with excellent signal, but when I open IE7, it will not connect to internet. I also tried using windows utility to connect with same results. I currently have a different laptop hooked up, so I don’t think it is the router. any ideas?
