I have upgraded my network a tad...a couple of weeks ago, Newegg was having a sale so I replaced my slowly failing WD black 1.5GB HDD with a 2TB SSHD for $95 and found a TP-LINK 1Gb 8-port unmanaged switch. I do plan to purchase or acquire a managed switch at some point and play with VLAN and what not. I've been playing with Asterisk at home because my IP Telephony course is pretty weak thus far. So here's my layout:
WAN:
Charter 30Mbps Cable Modem (Might be the same as brandon's) with 1Gbps port.
Router:
Asus AC66r Router (Been an excellent router! the most recent firmware upgrade resolved issues between the modem and router after a loss of power where the router had issues pulling an IP address)
LAN:
> 1GB to TP-Link 8-port 1Gbps Switch
> My workstation
> Denon AVR1613
> PS3
> Bench connection for diag/repair/new builds.
WiFi:
>2.4 and 5GHz on a single broadcast WiFi SSID for now. Can have 6 seperate WiFi networks with factory firmware.
> Android and Windows phones.
> Tablets
> Laptops
> Nintendo Wii
> Brother 2270DW Printer (may change over to LAN since it's a mere 3ft from the switch, but this printer has been the best WiFi printer I've ever dealt with...professionally and personally...)
> Vizio 32" TV (upstairs, not doing wiring runs in this place...yet..)
> Her and the Kids' workstation
> Samsung BluRay player
I do plan to have a file server in-place by next summer (when I have $$$ again), not sure if it'll just be a NAS or a more fully featured server to play around with. I do know that I will pay around with both Ubuntu/Zentyal and Server 2012 R2. Though I feel I'll settle on Ubuntu from what my research has led me to believe for my needs. My WiFi range is excellent with this router, even on a shelf in the basement I can reach both ends of my pretty sizeable back yard without issues or the need for an AP. That makes me happy! Sure it's not as-fast-as 5Ghz a few feet away...it's fast enough for streaming, music, enough for me to do that and do homework on my laptop.
All cable is CAT5E, I terminated about half of the wiring to make custom lengths for my short runs. Nothing crazy since I live in a rental atm. Very basic network, but has been rock solid once I replaced that crappy cheap Belkin router with the Asus beast.
