> Hello! I always have a problem with channels. When I set the same Pan ID to xbee modules, they may have different channels. Then change module from coordinator to router, after that they find same channel and work. But after several time they stop working and when I check they have another channels. So, why does this happen??? PS:Sorry for my english) and thanks!

What good is CH - what exactly is the “operating channel”?

From the sounds of it, you are using the Zigbee version of the firmware. In the Zigbee version, the channel is auto selected by the Coordinator based off of the SC value and the noise on the channels scanned.

Try issuing a local network reset (ATNR0) on your router if it is not Joined with the Coordinator or before you power off the router.
