Occasional inability for a client to access anything on secure wifi (RT-AX5400)

[jesup]

I have a system with 3 RT-AX5400's, wired backhaul. I have a secure network and an unsecured guest network. Occasionally when I unplug a laptop from wired connections and go elsewhere in the house, it will get into a state where I'm connected to the secure network but can't access anything (including the router). Disabling WiFi and re-enabling it doesn't fix it. The only solution is to switch to the unsecured WiFi SSID. Note that when this happens, other clients on the secure network are fine. This happens to both Mac and Windows laptops and Android cellphones (Samsung S24's), though I'd guess more often on Windows.

All routers are on the latest firmware. This has been happening for quite a while, at least 6 months if not from when I installed them 1.5 years ago.

Perhaps something in the router(s) gets borked rarely on a handover as I walk around the house with the laptop/cellphone?

Thanks for any help/suggestions.

Maybe it is more of a client issue. Does the issue go away if you reboot the client ?

I'll try that, though this has affected at least 3 different laptops (2 mac and one windows) and a couple of android phones. Typically after going back to wired it's ok (though I generally I need it for a meeting and can't reboot; I just switch to unsecured). It does affect the windows laptop more often than the others, I will try a reboot if I have time next time it happens.

You really haven't provided enough specific detail to narrow in on the trouble. For instance, I could conclude that your wired/wireless clients connect fine to your router LAN and WLANs but can't access the Internet when you connect them to node WLANs.... so your node backhauls/AiMesh install is not healthy. And why do you have unsecured WiFi?

Given 1.5 years of service and on current firmware... when is the last time you Hard Reset the firmware and configured from scratch?
