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:
