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 “Current Interface Address” and “Current Peer Address” fields in the screen below:

When the connection is
In this situation an external antenna can boost the signal enough to provide a sustainable cellular connection.
