Try using Coordinator AT (20A7) and Router AT (22A7). Make sure that you can pass the range test first before you move on to your Motes.

If you can’t pass the range test then the two radios are not associated or you are not running the range test correctly. To address this, I would suggest issuing an ATNR0 on your router before you short Data in to data out on it. Then see what happens.
