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??
