I use a GL-AX1800 Flint - Firmware 4.1.0 with a wireguard connection which randomly hangs.
The status in the webinterface will be an orange indicator - “Client is starting”.
I have to manually stop and reconnect the wireguard connection to restore the connection.
I have no idea why this is happening since I have a fiber connection (no reconnects by the provider).
I didn’t have this problem with the 3.x firmware.
