R510 -- frequent heartbeat loss and video freezes

rich47 — Tue, 13 Jan 2026 17:34:20 GMT

I have 7 R510 APs on a home network, with a Luxul ABR-5000 router and Luxul 1208p PoE switch. Generally, everything works well, but in the last few weeks, the video on my two Apple TVs was freezing often enough to become annoying. I spoke with Apple and my ISP (Quantum Fiber) and ruled out any problems with the TV or my incoming signal. When I looked at Unleashed, I saw frequent heartbeat loss and application reboots on my APs, but mostly on two of them I checked the internal cables, which seem to be in good shape. I added a couple of PoE injectors in case power loss was an issue. I set static IP addresses for each AP and designated one AP as the Master ((when my internet seems frozen, I check the Unleashed UI and have sometimes seen up to three Aps designated as "Master"). I downgraded the firmware to 200.14.6.1.203. Nothing seems to have fixed the problem.

I welcome suggestions for what else I might look at to solve the problem. I've attached a list of recent alerts, which have become more frequent.

If you remove the two troublesome APs temporarily, is the rest of the network stable? That would be my first troubleshooting step.

Next I would try setting up a fresh Unleashed network consisting of just these two APs on a separate VLAN on your switch. If they continue having application reboots I would suggest the APs are faulty.
