Networking between two buildings - issues!
First post here - sorry if these questions are answered elsewhere, but I'm quie busy and haven't had time to search.
Having had problems with network traffic I recently bought an Ethernet extender to cure the problem, but it hasn't worked.
Let me explain. We have two buildings connected (over telegraph poles) by approx 80 metre length of external grade CAT5, which worked fine for some months. At some point over Christmas, the connection dropped out and there was massive (approx 30%) packet loss. We put in another length of cable with the same problems. I was hoping the Ethernet extender would boost the signal enough to cure the packet loss but it doesn’t seem to work. Plugging in to different sockets on the POE switch at the “near” end makes no difference.
The strange thing is, if you plug a laptop directly into the “far” end of the cable, it works fine (though it handshakes down to 10MB). However, if you attach it to a hub/switch the connection is lost (computers won’t be issued IP addresses, and if you used fixed IP there’s no traffic back).
I’m completely at a dead end regarding solutions – I can’t think of anything else to try. The likelihood of having two damaged pieces of cable is minimal, but I can’t run a third attempt without buying another drum – which would be good money after bad at this point. Suggestions would be welcome!
