We have problems sending out data (emails with attachments, ftp transfers etc...) from our ethernet network. We have full download speeds of over 5mbps, but our upload speeds are >100kbps.
We are receiving our internet connection from another building in the commercial center we are in. We've isolated the problem to a CAT5 cable running in a metal conduit under the parking lot. We isolated this by testing the speed at various points in the network. Computers before these cables run fine, but all of them after have these slow upload speeds.
The strange part is that there are five (5) CAT 5's ran through that conduit, and all of them are having the same strange problem. We only use one, but tested them all.
Do you know what could cause this kind of data loss, but only in one direction? I was thinking the conduit filled up with water, but why doesn't it affect the speed both ways?
Thanks in advance for any insight you can offer...
