I have recently bought the new Dell Inspiron 1520 which have installed Vista Home Premium and have Intel AGN 4965 card. All was going well But after few days I found that I cannot connect any wireless network that my card sees. I can see there are four wifi network in which one is mine. I have WAP security on and I cannot connect to any of the nonsecure networks. When I try to connect it then it prompts me for password and it accept the password but it is still not able to connect. I have never seen such issue before. Please help.
