I have a table top computerwith wireless router in the house. wanted to be able to connecet the internet in our party building and ran 150 of cable to our party building (underground through PVC pipe). The cable works when plugged into the laptop out in the party building. When I plug the cabe into the extra router in the party building the laptop says tht the signal strength is excellent, but when I try to connect to that device, it will not connect. Any ideas? The router in the party building is a centurylink router.
