I have two machines configured as wifi access points that use the athn(4)
driver. One is an Acer Aspire One D250 and the other is an ALIX.2D13 with
a Compex WLM200NX Atheros 802.11 a/b/g/n miniPCI card. Both have OpenBSD
5.4 release installed. I've been able to reproduce the problem reliably on
both. The following is one procedure I used to test the problem:
-boot machine with athn down
$ ifconfig athn0
athn0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
lladdr: xx:xx:xx:xx:xx:xx
priority: 4
groups: wlan

status: no network

$ sudo ifconfig athn0 inet 192.168.2.1 255.255.255.0 nwid 1234567890
wpakey keykeykey mediaopt hostap
$ ifconfig athn0
athn0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500

-edit dhcpd.conf and run dhcpd daemon
$ sudo /usr/sbin/dhcpd athn0
-attempt to associate from MacOSX and WinXP machines
-not able to see nwid on WinXP after refreshing list multiple times
-can see nwid on MacOSX, but connection times out when trying to
associate
-change channel on access point
$ sudo ifconfig athn0 chan 7
-association with AP is successful from MacOSX and WinXP machines now and
IP addresses are assigned
