Can't connect to internet?

[Noah]

I have reset my modem and router in so many different ways, and it always ends up with a couple of red lights on my modem (some lights aren't on) and my router flashing red, when all lights should be entirely green. Whenever I contact my service provider it sends me from the website to customer service, then from customer service to the website in an infinite loop. So I have to ask this question while using up data on my phone.
