You don't have any mac address filtering going on do you? On the touch pro did you make sure to deleting the old network and then adding the new one? You can delete the network under Settings > connections > Wi-Fi > hold down your stylus on the network and pick remove.

Also why are you still using WEP? Just to let you know it's not entirely secure also hiding your network really only serves to add a layer of difficulty that you have to deal with when setting up your devices. The rest of the world can and still does see hidden networks.
