I have a Laptop running Windows Vista. For the last two years, the laptop connected successfully to my D-Link 655 Router via WPA2. In addition, the laptop has sucessfully connected to many wireless networks without incident.
Yesterday, I swapped a Netgear 3700 Router in place of my D-Link 655 Router and everything worked fine except the laptop. When I tried to connect, I got a message saying that the computer had local access only and I was unable to connect to internet.
After several hours of troubleshooting, I swapped back to the old D-LInk router and everything worked fine.
Since I have two internet connections, I decided to turn on my second wireless connection which also uses a Netgear Router. Tried to connect the laptop to the second wireless network and the same problem occurred. After another lot of troubleshooting I was able to get it to connect to the second wireless network if I used WEP Encryption.
So I have a Vista Laptop that works fine but cannot connect to two Netgear routers using WPA2 Encryption.
I have Google the Net many times and tried numerous remedies including shutting down IPv6 and a Registry key fix to turn off DHCP with no effect.
