Tried to replace plugs on a few cables.
Now they don't work.
Have not done this in 20 years or so ......
Is this the correct wiring for a normal cat 5 cable?
Not sure why it isn't working
I got some bum connectors, the cartridge would not seat no matter what you did, battled to crimp and just gave endless problems.
Tossed the lot and got some from Scoop and they just work, you fit, test and move on.
Try a different make perhaps.
