So i have my modem+router on the ground floor of my house from that machine i run a rj45 cable to my first floor bedroom for better speed. This rj45 cable is a cat6 cable which is 25 meters long.
Recently this connection stopped working so i checked the cable its not broken anywhere, so i tried connecting this cable directly to my laptop and this ethernet connection was not recognised. I tried to use a seperate router with the same cable and it didnt work either.
So my final conclusion is that the port itself is broken. Does anyone know if this can be repaired as i dont want to throw away a perfectly good cable.
