Xbee series 2 Intermittent Packets - xbee

Question

I have two xbee series 2 (ZigBee) radios, and I am having some trouble getting them to communicate properly. One xbee is running the ZigBee Router AT firmware version 22A0, and one xbee is running the ZigBee Coordinator API firmware version 21A0. The ZigBee Router is also set to sample DIO4 (digital pin 4) every 100 ms. The ZigBee Coordinator is connected to my computer with a USB explorer, and I am using the "new" XCTU program to read packets from serial. The ZigBee Router is simply being powered by a 3.3V connection. I can see some ZigBee IO Data Sample RX Indicator packets come through but they are intermittent and not consistent. Also, I have trouble discovering the remote node through XTCU. Below I have posted the saved profiles for both the router and the coordinator so you can see all of the settings and firmware. Is this a configuration issue or is one of the radios bad?
