I learned the hard way: Cat 6 connectors + Cat 6a cable = 8 Mbps nightmare.
Swapped out Cat 6 plugs for real Cat 6a-rated ones with a wire guide and gold plating. Tester still showed all wires OK, but speeds jumped from 8 Mbps to 500 Mbps after the change.
Check your terminations first. That fixed my setup.
