I've tried to reset firmware, reset router and have tried to start htop but the problem is that system becomes completely unresponsive and logs simply so not occur.

Procedure Conducted as follows:
Enable AdGuard Home
Open New Window
Switch to port IP/: 3000 (AGH homepage)
Main Window on AXT1800 becomes unresponsive with errors to check the connection or reboot the system
At the same time, AGH becomes unresponsive.

Solution: reboot rouuter and quickly log in and disable AGH before VPN and AGH start up.

I have tried option to run DHCP on AGH to resolve clients, same thing.
If tried to log events with CLI, system becomes unresponsive still.

Only thing that allowed AGH to run for few hours was plugging in USB into port, go to Lucy-system-expand (Mount) storage, mount USB as swap and allow it to run like that.
