Have an AT&T all in one router with 4 ports, just got a new laptop and entered a wrong digit in the security key field. How do we get back to change it to the correct number...it won't let us go back in to do it, and it says we have limited access to our network but cannot connect, thank you. It's an HP with Windows 7
In Windows 7 Control Panel, find Network and Sharing Centre then Manage Wireless Networks where you can edit the details you put in teh first time around and put the matter right. There's nothing to change in the router settings in these circumstances.
