Installing Cable internet [View all]

So I think I've gotten as far as this:
1) Service must be activated by the cable company, and I need a DOCSIS3.1 cable modem
2)Then I connect the router into the modem.
3) need to configure the router and Wifi software. This is the real stumbling block.

How do I know if the router is suitable for this? I use a very old modem, about 10 years old, but also have a newer one about 5 years old, an Actiontec GT784WNV. It has a DSL modem, wireless networking, and full routing capability, says Verizon.

I use one PC via Wifi, I can also use ethernet. I wanted to connect a USB printer wirelessly, and a desktop Wifi PC as well, but never got that far.

Thanks for any insight you can give. It's time to ditch the landline. Cable internet is cheaper, and 20 times faster. This is a project for this year. Verizon does charge a disconnect fee.
