Hi I’m bumping this MichaIng because I am getting the exact same issue when trying to use Wireguard. As soon as I start the service, I start getting DNS resolving issues. Please see this thread: [Wireguard + Mullvad. How to?](https://dietpi.com/forum/t/wireguard-mullvad-how-to/3392/1) Do I have to go through the same steps as the other user? If this issue is similar (seems quite like it is) then I think it is safe to say that the problem is not resolved. I am also using Ethernet. This is my 4th fresh install attempt at getting Wireguard to work… EDIT: I’ve done my best to retrace the steps you gave the other user. > sed -n 3p /DietPi/dietpi/.network ```plaintext eth0 ``` Then: > lsmod | grep wireguard ```plaintext root@DietPi:/etc/wireguard# lsmod | grep wireguard wireguard 143360 0 ip6_udp_tunnel 16384 1 wireguard udp_tunnel 16384 1 wireguard ipv6 450560 42 wireguard,nf_nat_ipv6 ``` > dpkg-reconfigure wireguard-dkms Finished!
