2.1.5.3 Minimal Reception
On occasion, you can find yourself in a situation where you have just enough signal to be able to communicate with the
cellular tower and obtain an IP address, but not enough reception to be able to sustain a viable connection.
If your cellular card is using dynamically assigned IP addresses, you can determine if you are in a situation like this by
watching the “Cellular Interface” field from the Home screen (Summary ‐> Status) as shown below:
If you refresh this screen every few minutes and notice that the IP address is changing frequently, it is possible that the
router is connecting to the network and obtaining an IP address and then the connection to the cellular network is being
dropped. When the connection is re‐established, the device is then issued a different IP address.
