Check the gateway traffic page for response packets.

Make sure to keep at least 8 feet between a node and gateway to prevent cross talk caused by strong RF signals. (Which can cause the gateway to receive uplinks on a different channel, resulting in a reply on a channel on which the node does not listen for an answer)
