Thankfully I've learned to always make backups of defaults, so I still have it
I guess what's confusing to me is that the configuration file I created works just fine with hostapd in FreeBSD. Doing a little digging I haven't seen anything that specifies different builds between FreeBSD and OpenBSD, including scouring the hostapd main site (
http://hostap.epitest.fi/hostapd). In fact, the example hostapd.conf from their site, while much more detailed, is remarkably similar to mine...
Going to try and re-install using the 0.6.9 version directly from epitest, and see if that works. Thanks again for the help.
