D-Link 8-Port Gigabit Unmanaged Ethernet Switch for Office, Media or Gaming

This is quite possibly overkill, but I'm pleased with this setup at home:

    Cost | Purpose        | What
    $109 | Router         | PCEngines apu2c2 http://pcengines.ch/apu2c2.htm
     $10 | Router Case    | http://pcengines.ch/case1d2blku.htm
     $17 | Router Storage | http://pcengines.ch/msata16g.htm
     $30 | Gigabit Switch | https://www.amazon.com/D-Link-Gigabit-Unmanaged-Desktop-DGS-108/dp/B000BCC0LO/
     $80 | Wifi           | Ubiquiti Unifi Lite https://www.amazon.com/Ubiquiti-Unifi-Ap-AC-Lite-UAPACLITEUS/dp/B015PR20GY/

With this setup, the router only does _routing_, so you also need a Wireless Access Point (WAP). Connect it like so: Modem->Router->Switch->WAP.

Install pfSense on the router, configure the Unifi using Ubiquiti's Java app, and you're done. It's about $250 all together which _is_ more expensive than consumer routers, but IMHO it's worth the superior quality. The APU board is well-documented (PCEngines provides schematics!) and the firmware is based on Coreboot. The processor supports AES acceleration for faster encryption (great if you use VPNs!) PfSense is an enterprise-grade router/firewall with scads of graphs and features. And the Unifi has a great antenna with excellent range. Not to mention this setup leaves you with six spare ethernet ports on the switch.
