I have a 150m roll of cat5 cable. I created a 2m and a 5m and both worked no problem from a pc to a router.
I placed a 50m cable and tested it with a cable tester and it said it was perfectly fine. However when I connect the computer to the router it won't recognise a cable is connected. I even cut the connectors and added new ones to the cable, but still no luck.
The cable tester says everything is fine, but the computer is having none of it. I also tested the 50m cable with a laptop to the router and no luck there either.
I checked the 50m cable and there are no signs of stretching/tearing or anything that looks remotely dodgy. I disabled all wireless, and that didn't make a difference either. The cable doesn't run near any power cables either, so I have absolutely no idea what is wrong.
Any info/suggestions appreciated.
