I have a Zigbee PRO S2C coord. and Zigbee PRO S2C Router. FW ver 4060 on both units.
All works fine until I emulate a radio network failure (shield coord antenna). I wait until router assoc Led stops blinking before removing shielding and allowing RF connectivity.
Router consistently fails to rejoin.
If I power cycle Coord then router rejoins.
Why does router fail to rejoin after RF outage but rejoins after Coord power cycle?
It sounds like you need to change the NJ parameter on the coordinator back to the default value:

Hi DF,
No it wasn’t the NJ parameter (that affects ability to join). We found that the NW command was set to value of 1 thus an RF outage > 3 minutes was causing radio to leave network. Because NJ on Coord was set to 0 (to prevent uninvited joins) the Router would appear to hang. The Tip for others here is to be observant of terms join and rejoin.
