I have an AC5400x router. I love it and so far the speeds are great. I do notice one thing though. On some of the external antennas, they wiggle while others are tightly in. Does this mean the ones that wiggle will have issues since they are not in tight enough? Why is it that some of the antenna are tightly in while the others wiggle? Can I lose packets because of these non tight fit antennas? Is there a way to check the "health" of the antennas as well in case some of them are faulty?
