Just get a router with a WAN port and N lan ports. Internally, they're all a switch and a CPU with two independent ports. Sometimes the WAN port goes straight into the CPU, but quite often all the external and internal ports are switched and the WAN port is just VLAN isolated to one of the CPU's internal ports. I've accumulated half a dozen WRT1200AC and WRT1900AC devices from eBay for about $30 each. They have dual core 1.2Ghz ARM CPUs and something like 256MB of RAM. I use one with wifi disabled as my router (and run wireguard on it for my phone), two for APs in the main house, and another as a wireless WPS bridge to the garage. I can pump 400-500Mbps of TCP traffic over the wireless bridge. The router hardly even registers the wireguard traffic from my phone, but then my ISP link is only 46Mbps. I just ordered Netgear r8000p router on eBay for $40 to play with, at the recommendation of another HN commenter. It has 6 antennas for beam forming, a dual core 1.8Ghz ARM CPU, and 512MB of RAM.
