    Hi all.

    So I gave a GT-AC5300 as the master and two RT-AC1900p as nodes.

    I have one node that consistently disconnects. Causing my TV to lose connection. Once to TV reconnects to another node or the main unit all is good.

    I've checked signal strength, placement, I've tried stock and Merlin settings but nothing.
    Here us what happened when it disconnected this morning:

    Are you using ASUS AiMesh? Is the disconnected node no longer displayed under the router webUI Network Map? Do you have to re-add the node to AiMesh to recover it?

    What are Merlin settings?

    Yes, I am using AIMesh.

    The node still displays but shows as offline. During that time everything reconnects to the hub or other node. The disconnected node recovers after 3 minutes or so but repeats the process after a few hours.

    I haven't really changed any settings. I currently have Roaming, airtime fairness and universal beamforming disabled, but had the same issue with different settings (roaming on, ub on, etc ...)

    I believe AiMesh requires both radios regardless of backhaul. Have you checked to see if the node radios are still broadcasting when it goes offline? If not, then maybe a radio is failing, or the firmware is not right. For the later, I would reset, re-install the firmware, reset again, re-add the node, and hope for the best.

    Luckily, I never disabled any radios. Aimesh defaults to 5G-2 for backhaul without any intervention.

    How can I check if the node radios are still broadcasting if the node goes offline?

    A WiFi Analyzer app is a handy way to see WiFi signals come and go around you.

    Unlike a wireless client, a WiFi Analyzer will show a discrete signal for each WiFi radio broadcasting within range. If a node radio/signal is malfunctioning such that that node is dropping from the mesh and/or dropping wireless clients, you may be able to detect this by seeing that specific node radio signal drop and/or go missing.
