Have you taken a look at their Ultimate Dream Machine setup? They have three different models. I have the pro, and it's been rock solid. A friend of mine has the base model, and now wants to move up. Ubiquiti stuff can be addictive.
Here is my 2 cents on Ubnt.
They are great stuff... im rocking full enterprise grade UBNT gear, which is the UDM Pro SE + Switch PRO Enterprise.
I also have 5 Access points spread across 7000 sqr ft, and i get full bars even in my bathroom, so you can relax in the bath with a tablet and stream whatever you want.
However UBNT seems to only play nice with UBNT infrastructure.
This is why you will see many people complain about UBNT because they are not using the full infrastructure but a cambial form.
This will give you LOTS of headaches.
So unless your willing to invest in the full UBNT infrastructure, i usually do not recommend this route, as it gets expensive VERY FAST and difficulty level scales horribly, meaning as you want more, you better have a friend who is a real IT on standbye to help you walk you though some things as youtube will be limited in some stuff you want to learn about.
So here is my advice for the more budgetted approach, to people who know how to work with customized PC hardware.
(meaning your not a "Dude your getting a DELL person".)
1. Ditch all consumer routers.
Just TOSS them out, they are all garbage, and things labeled "gamer" is even more garbage.
That 800 dollar ASUS router you bought at bestbuys after listening to the Geek Squad guy claim its the best..
G A R B A G E.
2. Get something like a Fitlet PC or a Ootom's and protectii are also good.
Important thing is
MAKE SURE IT HAS AES-NI
fitlet is a fanless mini PC full of openness[imageeffect type="shadow" align="aligncenter" width="690" height="269" url="https://www.fit-pc.com/web/wp-content/uploads/fitlet-rm-banner.jpg" link="http://www.fit-pc.

3. Buy a PoE 8 - Port Switch. You can get a 2.5gigbit switch if you have 2.5gb devices.
(the PoE will help you tremendously if you want enterprise grade Wifi Access Points.)
4. Download PfSense.
pfSense is a free and open source firewall and router that also features unified threat management, load balancing, multi WAN, and more
www.pfsense.org
5. Go on youtube and watch a few videos on how to setup a Pfsense Firewall Router.
(There is a million videos on how to setup and config a Pfsense Router.)
6. Need Wifi, you can get UBNT access points, but then i recommend some form of cloud key, if not Zyxel Access points are excellent for the money, or you can also get eNGinus.
(Avoid TPLink Omeda devices, also i would avoid anything labeled "Mesh" as configuring them are a PITFA as they are meant to be dummy proof, with options only available for dummies, unless u break down a console and telnet into them directly.)
The only time i have ever seen someone upgrade from a PfSense system, is when they go on real enterprise setups like UBNT, CISCO, Broadcom, you get my drift.... things that require level 2 and level 3 switches, and are typically using also using fiber cables and not pure copper wire.
