Entire network drops when connectint to VPN on a client

Second day using the MT1300 and it has been working extremely well and everything I want is on there. I have the device connected using mobile tethering and I have a LAN cable going to my laptop. When I try to connect to Mullvad VPN (wireguard) on the laptop client, for some reason the entire network drops on the router and other devices can no longer connect to the internet which is really weird because that shouldn’t effect the router. I don’t want to setup a Wireguard server on the router itself, I just want individual clients to connect to a wireguard server. How can I resolve this issue?


If you do not use Mullvad on your laptop, the Internet works well?

It is hard to understand how Mullvand on your laptop crashes the router totally.
