Using the Ping Tool
Using the ping tool, you can check the connectivity between the Gateway and another local
or remote device. The Gateway provides a ping tool for conducting the ping with the default
Gateway, across the RF interface, or across the WAN interface. This tool sends a small
packet of data and then waits for a reply. When you ping a computer IP address and receive
a reply, it confirms that the device is connected to the Gateway.
To perform ping activities, use the following procedure under Ping on the Diagnostics menu.
1. Enter the IP address or domain name of a target host in the Ping field.
2. In the drop-down list to the right of the IP address or domain name, select whether the ping
is to be sent to the default Gateway, across the Gateway’s RF interface, or across the
Gateway’s WAN interface.
3. Click the ping button. The results appear in the Diagnostics – Ping Results screen (see
Figure 77 and Figure 78). The results screen may flash as the contents refresh during the
ping.
4. To close the results screen, click the Back button.
