I have a RUT955 (running RUT9XX_R_00.06.04.5) with MAC address passthroough enabled.
Whenever I do a change to the config for mobile connection and save, the RUT955 will become unresponsive, cannot even ping it anymore.
I have been patient and let it be for up to 20 minutes, but it wont get back up. If I do a power cycle, it will come back up again.
