End device take 8-10 minute to reconnect after Power cycle or NR command with version 4061

Hi
I was setup system with 8 end devices ( battery power ) sending data to coordinator after every 1 minutes interval.

I observed End devices are taking more than 8-10 minutes to rejoin the network, if power cycle given to coordinator or NR-01 issue from coordinator if i use xbee firmware 4061.

If i down grade xbee with ver 405F ( without change in parameter value) , End device connect immediately to coordinator. say within 1 minutes.

Please suggest any modification require in setting.
