Hi Jouni,

Thanks for looking at this.  I don't have much additional information.
Since setting "dot11RSNAConfigPMKLifetime=31536000" the connection has
been stable for the last four months.  I just tried reverting that
setting and I can confirm the issue is still present.

I'm not familiar with setting up a wifi sniffer capture, but if you'd
like to track this down and it's something I can do from this openwrt
based router or from a Linux machine then I'm willing to set it up.  I
don't think getting access to the AP is practical.
