Looks like I need a new magic box that makes the internet go (modem router thingies). Currently have a Netgear nighthawk AC1900 I think so what would be a good replacement for under say $300?
I have the same Modem-router, Nighthawk AC1900 D7000, I bought a router only TP Link AX73 and use the Nighthawk as the modem and the AX73 as the router.
Its now handles 4 x TV's, a few computers, 4 x phones, garage door, security camera etc...
I get full wifi in my bomb shelter garage, down the driveway and working in the back garden.
If you do go this way, make sure and login to the Nighthawk and in advance settings, select use as 'Modem only' or it will drop out occasionally. I only discovered this after a couple of months.
