Just recently my internet was working until my internet cord came out of the router, usually as i do i put it back in but when i put it back in i wasn't getting a connection it said 'Unidentified Network'. To make sure it was just the Ethernet cord with the problem i tried the wireless and the wireless worked. im not sure what to do is it the reltek family controller, the troubleshooting sure doesn't help the problem either. I do remember a while ago i had the same problem but i can't exactly remember what i did, when i do go into the network connections it says under local area connection "unidentified network,shared"
