Cat5e signal when coiled up
I routinely test POE network devices with 50m or more of coiled up cable attached to them, particularly when sorting out a new install (it gets to pass the first tests all coiled up before we run it out to the proposed location and test it, then run the final cable through the building.) So coiling is not the issue. 

The photos leave it a little vague, but the second one looks like you might have white/green and white/blue mixed up.
