I am using volatile PRI 1.1.4 + volatile STA 1.7.4 thanks to the latest changes in CVS,
and kernel driver 802.11 management.
I did further tests and I think I found out whats causing the problem.
It is related to power management.
If I enable power management on the PCCARD (my default set-up) via
iwconfig power timeout 3
(No PM on the AP-Machine)
and let the connection idle for some time, I get the re-association.
I cannot reproduce the behaviour if I disable power management with
iwconfig power off
Since you said that hostap is sending a poll frame every 5 minutes I think the following is happening.
1.) PCCARD goes to "sleep" after three seconds.
2.) My AP sends a poll after 5 minutes
3.) For some reason the PCCARD is not answering and the AP kicks it out, sending a message.
4.) PCCARD wakes up and re-associates itself.
Could this be the problem?
