I have been having issues for months now with my setup (AX86S primary and AC86U aimesh node). Finally took a deep dive into the logs while devices were having issues (refusing to connect to the network or having no internet access). Turns out it was the roaming assistant causing devices to disconnect and then not allowing them to reauthenticate when attempted to reconnect. The weird thing is I had my roaming assistant set to -70 dB and all the devices that it was force disconnecting were in the -50 dB range. Is roaming assistant just a broken mess? After disabling it I havent had a single issue with any of my devices.
