I am using a Netgear wireless router in my home. My desk top (Vista) has been connecting fine. Last night it would not connect so I set my laptop up next to it and it connects fine. When I look at the Network and Internet screen on the desk top, it show me with an excellent signal to the wireless router but shows the internet connection with a red X. I tried the repair function and rebooted the desk top a couple of times but still it has excellent signal from router but no internet connectivity. Yet my laptop sitting right next to it is OK. Any help would be appreciated.
