Turning an OpenWrt router into a wireless bridge with relayd

Mon, 31 Aug 2026 19:41:37 -0500

I had a spare TP-Link Archer AX21 running a plain OpenWrt snapshot, and a room with a couple of wired-only devices and no ethernet run to it. I wanted the router to join the existing WiFi and hand that connection over to its ethernet ports, so the wired devices show up on the main network like they were plugged into the main router. Basically, a wireless bridge.

The OpenWrt relay configuration docs cover what relayd is actually doing under the hood. Here’s the full set of commands on a plain install with no LuCI.

I recently got a hold of bunch of Minix brand Mini PCs for dirt cheap ($10 each) from FB Marketplace. I initially had a CUPS server running in my homelab but having to rebuild it, I figured I would use this one as a CUPS server to share my yet another dirt cheap USB printer from Marketplace as well. This would also let me not have to deal with bridging my homelab VLAN with my WiFI since the priority here was to let anyone in the home quickly print off things from their laptops or phones over Wifi. My current setup also involved putting the printer in the laundry room and run a long USB cable to the bedroom closet (aka homelab) which wasn’t ideal at all. At any point in time, someone could get snatched on it and bring my computers down to the ground. So I got into a mission to make use of one of these Minix boxes.
