Powerful Home Network Help

I am moving into a new place and I am ditching all of my old networking hardware. I have a 2000 sq ft single level house that is fairly square. I want the best performance and signal quality throughout the entire house. There will be three PCs connected via ethernet and between 6-24 wireless clients. I have a limit of $600 for the modem, router, 4+ port switch and wireless access point.

cool story bro.

So, uh, What's the question? Sounds like a simple setup to me. 

Thank you for not helping at all.

I wanted help selecting the hardware for the setup.

Asus makes nice stuff in that budget, doubt you could get some business cisco gear for that price range though. Make sure you pick up something with beamforming, might help decrease the degradation of your wireless network with that many wireless clients causing crosstalk.

Check out the ubiquiti unifi access points. 

You have a bunch of options for a $600 budget. I could get that up and running for half that price lol. http://www.amazon.com/RT-AC68U-Wireless-AC1900-Dual-Band-Gigabit-Router/dp/B00FB45SI4

I have been looking at the UniFi AP AC WAP and I was pretty sure that's what I was going to get but I still need the rest of the network hardware.

I tried that router already, I borrowed it from a friend, and there are still a couple of rooms in the house that are at the outskirts of the house that get a bad, if any signal. So I need something more powerful than that. Also the reason I have a $600 budget is because I want something that is better than what a consumer grade router, even a high end one, can give me.

have you thought about open source options? DDwrt in one very impressive piece of firmware, and unless you need AC speed through the home you can saturate a 2000 sq ft home easily with 2 N APs, each broadcasting the same network, or same set of networks, say 1 vlan for your use, 1 vlan for guest, so you don't have to give people access to the same network that your computers are on.

if you give us some more information it will be easier to suggest options. like what will your wan situation be, will u be sharing files over the internal network, do u need AC or is N good. you said that u used a router but did not have coverage is some parts of the house. could u use a second ap and do something like wds. every networking situation is unique and the higher end you go the more thought is needed to get the best value for money 

Maybe I am missing something, but are range extenders no good in your house or?
