There are a couple of things you can try here...first, you can make sure that you are not in "selective startup". There are times that when you are in selective startup, there is a service that can be shut down that keeps the wireless from seeing the internet. Second, if you have Norton or McAfee, they are the biggest cause of a loss of internet connect and it is the way that they handle the firewall settings. In most cases, deleting these programs or manipulating the firwall setting within them will get your internet connection back up. Your wireless network will say it is connected and with a strong signal, but if you cannot get on the internet, then that is most likely firewall. McAfee turns the windpws firewall off and uses it's own, that is where the problems come into play.
