Description

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.
