A great option I've found is to use the DietPi distribution that has Pi-hole configuration/install wizard built in (https://dietpi.com https://dietpi.com) After having various weird network issues and instability on a different OS with Pi-hole (updates often broke), I switched to DietPi, and now my PiHole and OS upgrades are extremely stable. The DietPi installer/configuration for Pi-hole sets up all the networking for you in the install "wizard", took all the weird networking headaches out for me
