Hello,
So recently I tried to manually set my DNS-servers to openDNS. I have successfully did this by removing "resolvconf" and "raspberrypi-net-mods" and then setting the addresses in the dhcp config-file. Every time I start my pi up, the DNS-servers are correct (meaning they are the openDNS-servers). However after a couple of hours, for some reason they change to other servers.
Would anyone have any idea how to fix this?
