Just bought the AX1800 Dual Band WiFi 6 Router to use with my IPhone 12 Pro so I can have multiple devices connected to the internet because I live in the country and have no other source for WiFi other than my phone. I cannot get the router connected to the internet via my phone. I purchased the Ethernet+ Power Adapter Lightning cable and have all of this connected to the router. I've also downloaded the Tether App and tried multiples times to get internet connected. Anyone on this forum successfully accomplished this and can you tell me how to do this? Thank you.
