wifi hotspot workaround

I have an athn0 wifi hotspot going.
I think I get wifi dissassoc attacks.
I know I'm just mitigating for now, but
I cycle the wifi interface periodically,
and that gets my client device back online.
I actually don't understand why cycling
the interface gets my wifi device back
online. Maybe it's actually a problem with
the athn0? The logs sometimes say
"athn0 device timeout" or mention
something about going into IBSS mode
WHILE ifconfig still shows it's in hostap
mode. Is there a way to interrogate the
interface's function to make sure it's
in hostap mode and test it's performing
that function? I'm just trying to
troubleshoot. I know the man page for
athn0 says there may be vulnerabilities,
but I don't even know what actually
transpires right now and want to see
if OpenBSD can enable me to just even
identify the issue. Thx.
