I recently discovered OpenBSD and eventually tried it in a physical PC. The PC is an Optiplex 790 with an add-in WiFi card. i5 2400 w/o GPU. The card internally is a Atheros AR9300, and it seems support is gone, as of this commit which lists issues with it, from 2014: https://github.com/openbsd/src/commit/a8c1d01a39b2bf4debd0358ce66f99d4bc391432
I am open to learning how to build and test OpenBSD in order to fix, but if any of you want to try this yourself I'll try to find a listing online for sale of this specific WiFi card. specific dmesg line for this device: "Atheros AR9300" rev 0x01 at pci2 dev 0 function 0 not configured
