Hi Misc,
I have used OpenBSD 4.7 on a PCEngines ALIX to create a wireless access point
(AP).
I am running hostapd, primarily to log auth and deauth of stations from my
AP.
After 72 hours of excellent running, my station loses wireless connectivity.
/var/log/daemon reveals that:
* AP sends a deauthentication to station
* Station sends an association request
* AP responds with association response
* AP sends a deauthentication to station
* Repeat to fade
I have read the manpage for hostapd, but I don't know where to look next.
Have had a brief look at the source of hostapd - I'm no developer, but nothing
jumps out at me.
Any suggestions appreciated!
(attached hostapd.conf, /var/log/daemon, dmesg)
Cheers now,
Joe.
