The owner of my company owns our building and the building next door. When they built the second building years ago, they ran a cat5e cable underground to connect the two buildings so they would be on the same network. As far as I know, that was working great. Later, someone else rented the building so we disconnected that cable. Now we want to reuse the building, but when I connected that cable back to our core switch, the other building gets about 1Mbps download speed (if it doesn't time out) yet gets ~95Mbps upload speed (we pay for 100/100). Pinging websites gives a time of 8ms but shows about 15% packet loss. These speeds are when I directly connect to that cable between buildings, if I plug that cable it into our rackmount switch, you can connect to our domain, but the network speed is essentially zero. Even locally, trying to access our server usually just times out. I'm not entirely sure how long the cable is, but it's about 50 meters between the buildings, and I know the cable run is not a straight shot, so it could be close to or slightly beyond a 100m run of cable.
I've tested the port on our core switch and I get 95/95 direct into my laptop. I plug that same cable into the keystone jack on the end of the underground cable, go over to the other building, plug into the keystone jack on that end, and get 1Mbps/95Mbps. Even then, it seems to slow down over time. Google will load fine, but try something like a news site, and it will start loading then grind to a halt and seemingly stop.
Interestingly, I tried using a little desktop gigabit switch early on to see if maybe there was something wrong with the switch I was using, and it did not detect that a live cable was plugged into it. No lights on the switch, and laptop said "network cable unplugged" when connected to it. Only when connecting to the more powerful rackmount switch would a connection be detected. So maybe it just is too long of a run? That or some sort of strong electrical interference underground are all I can think of at this point... Any ideas?
