Thanks! I resolved it last night... the problem turned out to be on the gateway side, I think.
I disconnected and reconnected all of the wires and when it came back up, the debug log showed signs that they were talking. 
You are correct, the MY_NODE_ID line was too far down in the code... I made a lucky guess and moved it up higher and then it started working.
Thanks for your help!!
Thanks again for your time!
The change caused an error:

Here is the altered code:
/**
* @def MY_NODE_ID
* @brief Node id defaults to AUTO (tries to fetch id from controller).
*/
#ifndef MY_NODE_ID
//#define MY_NODE_ID AUTO
#endif
Thanks for the reply! It didn't seem affect much... I changed the code to look like this:
...
#define MY_NODE_ID 5
#define CHILD_ID_HUM 0
#define CHILD_ID_TEMP 1
...
Which caused the compiler to throw this warning:

...it still compiled, but the serial monitor still shows the same errors.
Hi- I created a simple DHT22 node and an ethernet gateway. It worked well for a few weeks... until I moved the gateway and the sensor.
The sensor log shows:

...so this implies the problem is on the sensor side, correct? Using that logic, I rebuilt the sensor with an Easy PCB board, a new radio, and new arduino and get the exact same error!
I've got a 10uf cap on the radio power. I've switched out the power supply several times... it's currently on a 5v 2a supply. I've also switched out the supply on the gw side, but that's about all I've done there.
The code (on both sides) is the example code.
Ideas? Thanks!
