Depending on your bandwidth needs an old laptop + switch can suffice (using vlans and a one-armed router approach). I currently have an EdgeRouter-X running openwrt and are relatively happy with it. I think I could eek more bandwidth out of it but honestly I'd rather not fiddle with it. I have some Unifi AC-Pro access points and am pretty happy with those. Combined router/access points devices are the networking equivalent of TV/VCR combo devices.
