---------------------------+---------------------------------------
I'm playing with OpenWrt for a few days and I noticed the group key
handshake in wpa2-psk network apparently causes 25 second lasting
disturbance in connection.
The disturbance period starts with this kind of message on AP:
Thu Dec 3 10:02:09 2015 daemon.info hostapd: wlan0-1: STA
xx:xx:xx:xx:xx:xx WPA: group key handshake completed (RSN)
There are no messages in the client, it is not disconnected, but no
connection is possible, no pings replied.
The routers used are
AP: TP-LINK TL-WR842ND v2, running Openwrt r47532
client: TP-LINK TL-WA830RE, running Openwrt r47670
Network is WPA2-PSK using WDS and guest network.
--
Workaround:
option wpa_group_rekey '0'
in /etc/config/wireless
causes the key is not renewed and no disturbance occurs.
--
I found no reports of similar behavior so maybe it's caused by some
atypical combination of options in my configuration.
