If you do the above, also remove the camera from Settings, My Devices. However, all you really need to do is to either connect the camera to the new router through the existing cable (if that's how you had it connected before) or change the network in the camera settings. If you used the same SSID and passphrase from before, it should automatically connect with no intervention.
