There is a wifi router at my home. It is working fine. There is no issue with connectivity. There are around 6 different devices which are connected to it. There are mobile phone, a xp tablet, a xbox, etc. My aunt brought his laptop that has vista. Now all devices are working except that Vista laptop. It is not able to get proper configuration. When I try to connect the same I am getting a error related to SSID. The laptop configuration just stuck on the connecting network but it is not getting valid settings.
