I've got a RUT955 (latest 6.07.7 firmware) which I did setup for Nord VPN last week, which worked fine until anything caused the mobile connection to reconnect (either just a loss of service, or the router was restarted), at which point the VPN would not reconnect until I manually disabled then re-enabled the VPN profile.
To get around issue, I've disabled the VPN for now, and everything was back to working fine, however we've had some power cut issues this week, and it's highlighted a couple issues.
Sometimes the router fails to reconnect mobile data. The mobile signal shows as OK, but the mobile data doesn't connect. I have to either restart the connection, or reboot the modem for the connection to establish.
Then this morning after another power cut, I couldn't get any internet activity despite mobile data showing as connected.
After trying a couple router reboot attempts, I still couldn't get any internet. I eventually traced it to a DNS problem. Setting the WAN DNS to manual and entering my VPN DNS settings, got things working, and they kept working after I set them back to using the providers advertised settings.
Does anybody have any suggestions as to how to make the router recover reliably?
