When you set up a wireless network using AT&T U-verse Internet service, anyone within the wireless router’s range can connect to the network if it is not secured. Securing your network helps keep unauthorized users out, but you and your guests are also locked out if you forget the encryption key. If you forget your key or want to let guests use the network and and do not have it written down, you can access the router’s administration page from a connected Web browser and retrieve the encryption key.
