Comment Started with homebrew, switched to MikroTik (Score 1) 247
I wanted better control of my home network. Mostly filtering the internet for the kids and later scheduled blocking of their devices overnight, plus some playing on the side. I got a refurb Core2 desktop, snagged a leftover dual port NIC from work, and ran ethernet from the basement to the first floor to an AP. First I used pfsense and then Ipfire. It worked great. After a couple of years I started to think of the power usage of a full desktop running at 3%-5% utilization. So I went looking for an alternative. The RouterOS in the MikroTik boards had everything I needed as a drop in replacement for the PC. I got the model in the link below for ~$50. It doesn't have wifi but I already have the AP setup. It uses so little power the power adapter is similar to what you use to charge your phone. It can even run on PoE. I've been using it for about a month with no problems. Now I'm considering adding in one of their 802.11ac APs for $45 because the RouterOS is the same on both devices and the router can manage the AP. Assuming I'm understanding the manual correctly.
