TP-Link Access Points stop accepting some connections

It's a good thought, but my understanding is that the devices stay at the desks. I suspect they were made wireless only because existing wiring didn't exist and it was easier at the time.

I'm currently most suspicious of the APs. I'm going to run down the settings and also update the firmware. I'm just hoping that I get to witness the issue. It's always fun to try to troubleshoot an inconsistent issue like this.
