Wireless routers and other tech things

[Adrenaline_6]

I'm wondering if all of this stuff is way more complicated than I need. I'd only use two ports - one for the PS4 and one for the Verizon network extender and just something strong enough to cover the whole house.

If you already have a modem/router with 4 ports on it, that is all you need along with the Ubiquiti AP for starters. The AP will take 1 of those 4 ports and you will use 2 more and have 1 spare. Then just get into your router webpage and turn off the existIng WiFi on that router because you will no longer need it due to the new AP you will be adding. All you will need to do is run a Cat5e or Cat6 cable from your router to your desired centralized AP location.
