Customizing the Modem

Customizing and Testing AoT Modem Configuration

In this guide, we assume that you're running an Ubuntu based Linux system. We use wvdial to manage our modem connection.

Installing wvdial

sudo apt-get update
sudo apt-get install wvdial

Template Config

This is a template of the configuration we use on our AoT Chicago nodes. This file is located at /etc/wvdial.conf.

[Dialer Defaults]

Testing the Configuration

After saving the configuration to /etc/wvdial.conf, please run:

wvdial

It will take a moment, but should indicate that it has received an IP address. After this, you should be able to ping an external site:

ping google.com
