gigabit cat6 cable connecting 100Mbps only (Electrical interference?)

  • 772

I have a gigabit switch and I am connecting my laptop to it using a cat6 ethernet cable.

The problem is it is connecting to 100Mbps only instead of 1Gbps.

This is what i found :

  1. The is a zone in which the cat 6 cable passes where there are electrical connections and wires... at some point the cat 6 cable crosses an electrical wire
  2. I tried to remove the cat 6 cable from this zone where there are electrical wires ... when I do this my laptop connects at 1Gbps
  3. So I am pretty much sure there are some kind of interference with the electrical wires
  4. I have tried to make the cat 6 cable cross the electric wire perpendicularly instead of parallel to it... this does not work .. I stil get 100Mbps

I am obliged to pass the cat 6 cable in this zone.. there is no other route... what are the solutions to this problem? How to avoid interference with the electrical wires??

  2. I understand that moving the network cable or electrical wiring isn't practical for you. If that's the case, then if electrical interference is the problem, electrical shielding is the solution.

    I guess the cheapest experiment is to contrive a simple shield from aluminum foil, and ground it. (I assume that doesn't violate any building or electrical codes.) If that works, you might be able to run your network cable through some electrical metallic tubing (EMT).
