Can't connect to router in any way

Hello :waving_hand:
So, I wanted to set up WireGuard to forward all connections to Mullvad, so I found and followed this guide - http://forum.mikrotik.com/t/v7-1beta2-development-is-released/142356/1
Everything was going well - I created an interface, set the private key and endpoint on peer etc., but crucial moment happened after I followed this step…

  1. Finally add a new route in the terminal, like this, /ip route add dst-address=0.0.0.0/0 gateway=[your wireguard interface]@main routing-table=VPNProvider

Immediately after I wrote this command WinBox connection was lost, as well as internet connection in general.
I rebooted the router several times, it was booting as normal and Wi-Fi access point was discoverable, but I still couldn’t even access local network from both wireless and wired connections.
I used the RESET button to reset the configuration, Wi-Fi AP disappeared but the router still had previous symptoms - no internet connection, no local network connection, no router connection
I’ve gone for last resort and netinstalled it, but still no success.
I tried connecting via MAC address, using two different PCs and it still didn’t work. To exclude possibility of broken Ethernet on PC I tried with other router laying around and it worked perfectly.

To sum up: I have fully working and booting router, but i can’t access internet or local network or router settings, it just doesn’t want to, and I don’t even know what to do.

Device: hAP AC lite, RouterOS version was 7.13 stable at the time when it was working perfectly.

It seems you have not removed configuration, try again reset and when doing netinstall make sure you set option to remove config.

There was an option called “Keep old configuration” and I didn’t enable it. Or should I?

That’s correct, also check do not apply default configuration and you will have clean device, try again.

Seems like I needed to enable that “apply default configuration” button. Now it’s working like a charm!
Thank you for helping :smiling_face:
