Here's a reference for CAT 5 cable specs:

I doubt anything non-metallic would hurt it. But if you crush or bend
sharply RF cables, that can be bad for quality. Or winding it a lot
(adds inductance). More often connectors are on improperly, or the cable
itself was the wrong thing for the job to start with. If it is a 100
MBit/sec network, you should have the "fast cat" (cat 5e I think) cable.
If you put your own connectors on, be double sure that they are perfect.
