Our house internet and WiFi system works with the Spectrum Modem/Router, our own VPN Router, and a PiHole connected to the Spectrum Modem/Router.
If any of these systems are down then our internet will be down.
Internet comes into the Spectrum Modem/Router this Internet is called: Mustang 2. This Internet is then sent to the Pi Hole.
The Pi Hole takes The Internet and takes the ads out and sends them to The Void for eternal punishment
The Good Internet then gets pushed on to our VPN Router.
The VPN hides any device that is connected to it from prying eyes (gov't, hackers, your mom, etc.). This connection is called: Mustang
It is important to use the Mustang connection to ensure you are connected to the VPN and the Pi Hole
Most issues are fixed with a proper power cycle in order of how the internet comes in (Spectrum Modem/Router, Pi Hole, VPN Router)
If the internet is still down, it may be the VPN that is causing issues and you will need to change it
