Before I got employed with this company, someone ran a cable from the wall in the conf. room to the back server room and into the switch. Now when I started here about 8 months ago it was working fine. Until about 2 weeks ago we had no problems accessing the internet from that outlet. Since about 2 weeks ago we can get absolutly no network activity. I've placed a terminator at one end of the cable in the server room (the one coming from the ceiling from the conf. room) and placed a cable from the outlet to a cable tester and it says the cable itself is fine. Whenever i plug the cable from the outlet into my laptop, it turns off the "Network cable is missing" notification but i still get no activity. I know if the outlet wasn't live, it wouldn't turn off that notification so something must be going on here. Any ideas?
