R6900v2 — Nighthawk AC1900 Smart WiFi Dual Band Gigabit Router

I am having issues with this router connecting to my IPhone. Last night I lost connection to my TV (Firestick). I3 Broadband and I had many issues getting it connected to the internet when setting up. TV is working now, but the router won't connect to my phone. At first my phone said it was connected (for about a day and a half) and now it's not. Seems there are too many Tech issues, no support communication, tasks to do on my own, etc. Returning the router and renting from the internet company seems like an easier and way better idea.
