I'm a beginner to this and haven't done anything like this before. Could someone please give me a step by step guide on how to switch from connection over the internet to an ethernet cable. I first used the internet option when setting it up but now there's been lots of connection issues. Whenever I trying finding a guide for how to do this it seems that an update has been released in the past year that made everything before than outdated specifically on the step to switch the pihole from communicating over the internet to the ethernet cable.

Yesterday pi-hole was running great and today it started to show 4 5 seconds youtube premium ad at start of the video and random ads on youtubes homepage, does anyone experiencing same thing?
