Connected my laptop running Windows 7 to a Netgear WG103 access point but cannot access the internet. I ran an IPCONFIG and I have a IP address and I can ping the default gateway but no internet.. I check the Network and Sharing Center and it shows that my computer is connected to the wireless but has a big red X for the connection to the internet and says local access only. Tried reinstalling drivers, rebooting, safe mode, virus checks and nothing worked.
I had the network authentication for the access point set to WPA2-PSK. I remember reading somewhere that some have had problems with Windows 7 and this form of authentication. So I switched the network authentication to WPA-PSK & WPA2-PSK. Once I did that the Windows 7 machine connected to the internet without any problems.
