These RJ45 connectors are all undersized resulting in a loose connection to the ethernet ports of all devices. So weak, in fact, that the connection regularly breaks when the cables are pinched and does not reconnect until you reinsert the plug correctly. I realized how widespread the problem is. Switches, routers, patch panels, wall outlets, PC ports, they all lose their connection. I even used a cable tester to make sure I didn't have too much crosstalk on my end devices when I plugged everything in, so it's definitely those jacks. Now I have to go back and re-terminate all 46 wire ends I've done so far. Don't buy this.
