No signal when cabling a female wall plate
Never strip wires like that for a jack. It is very easy to short them together inside when you close the jack.

You also should have a cable tester that tests every wire individually. The best one I've ever used costs less than $10 (US). It has a series of lights 8 lights and tests each wire one at a time to make sure the connection is good. If you test your cables, you will see exactly what is wrong with them.

As noted in the comments, you must have a punchdown tool or use "toolless" jacks. This kind of jack is designed to crimp the wires into the terminals using pressure from closing the cover. I use these all the time - they cost only a few cents more, and they are much easier.
