Win 7 will not connect to network on restart

I replaced my 802.11g router with a new 802.11n router. I have three Win 7 Pro 64 bit PCs on the network. One of the PCs will not reconnect to the network when Windows starts. Each time Windows starts I must open Network and Sharing Center, select the network, click Connect and re-enter the WPA2-PSK key. The other two Win 7 PCs reconnect automatically as they should. What should I try to fix the PC that will not reconnect to the WiFi network? Thanks.

When in doubt you should delete the old wireless profile and create a new one with the correct SSID, password, security details etc. You can find the wireless profiles by going to the Network and Sharing Center, then look to the left for "Manage Wireless Connections".

You will always want to update the driver for the wireless NIC with the problem, sometimes the manufacture's site will have the latest driver.
