Vista cannot connect to my wireless router

I am using a Netgear router with the latest firmware and I am able to connect to the wireless network with the XP laptop that I have, but Vista wont connect to it. This network is shown in the list of available wireless networks and if I try to connect to Vista then it will ask me for the password but then the connection will fail with a message "Wireless association failed because Windows did not receive any response from the the wireless router or access point." The wireless NIC is an Atheros AR928X and it also has the latest Vista driver. Can anyone help me out please.

Can you tell us whether you are using WPA2 or something else, why dont you try to use the WPA2 personal and see if that solves the issue.

You can try to connect to the router through the XP computer and then disable the encryption. After that you will need to ensure that Vista computer is able to connect without encryption. After it has started working then log again to the router and then enable the encryption and put a new password.

Have you tried to reset the router and checked if that works. If not, then go to the network and sharing center and change the follwing things:

Network Discovery : On
File Sharing : On
Password Protected Sharing: Off

After that ensure that the network type is set to Private and not to Public. Have you also tried to uninstall and then reinstall the Wireless adapter drivers and then tried to re-connect to the router.
