Just so we're all on the same page.? I am not using a unify switch.? Not even a POE switch.? Using the supplied POE adapter.? The problem doesn't seem to be brand specific.? Random new device failure to connect.? The ones I can't get to connect through the AP will connect directly to the Fios router.? I'm wondering, everything you buy these days seems to be wifi compatible. Washer/dryer, refrigerator, coffee maker and a whole slew of other things.? Even if you are not using it, can they clog up the LAN?
