@David-TP

Thank you very much for the reply. I have Beamforming and fast roaming off, failed to mention those settings. I've had them turned off for many months while trying to solve this issue. Same with Mesh connection to the ESP devices.

The one setting I've not tried is High Capcity Mode. I've been hesitant to try it becasue one of my X50-outdoor units is wirelessly connected to another X50-outdoor unit (which is on Ethernet backhaul). That first X50 is at my barn running automations and equipment for animal feeding, doors, and lights, etc. I was concerned flipping that mode on may disconnect that remote X50, however it shows a Strong signal (2.4GHz/5Ghz) back to the house, so perhaps it will stay connected using 5GHz.

I'll have to plan a day for that test when I can monitor the situation more closely in case I need to intervene with potential disconnects affecting my barn.

Will a setting for assigning different 2.4GHz channels for mobile devices become visible after changing to High Capacity mode?

Currently I only see that option under Wi-Fi Settings Advanced per network, not per node or device.

Thanks again!
