Check the network connections settings for your operating system.

The connection to the terminal should be the only active connection. (In normal operation, it is best to have only one active connection.)

To check this:

• On a Windows PC, select Start > Control Panel > Network Connections. If you see an open connection other than the terminal connection, right-click on the connection and select Disable.

• On a Mac, simply make sure that the wireless and Bluetooth interfaces are disabled.

• USB drivers are not installed or need to be reinstalled
• Check for latest version of USB drivers
• Check USB cable and connections
• You must install USB drivers onto your computer before you can connect to the
  terminal over USB. The required USB drivers are provided on the installation CD
  supplied with the terminal, or can be downloaded from http://www.inmarsat.com/Support/detailsupport/bgan/Softwaredrivers/index.htm

When you connect the USB cable from the terminal to your computer, your operating system automatically discovers the terminal as new hardware. Follow the on-screen Wizard to install the terminal.

On the EXPLORER 300, 500, or 700, and Nera WorldPro 1000/1010 (Windows PC only) – To check that the installation of USB drivers on your computer was successful, display the list of modems on your operating system. To do this:

• On a Windows PC, select Start > Control Panel > Phone and Modem options, then select the Modems tab. If two ports associated with the terminal (either Thrane & Thrane or Nera) are displayed, the drivers have been installed.
• On a Mac (drivers only required for a Thrane & Thrane terminal) – select Macintosh HD > Library > Modem Scripts. If two ports associated with the Thrane & Thrane terminal are displayed, the drivers have been installed.

On the HNS 9201 – To check that the installation of USB drivers on your computer was successful, connect to the terminal and look for the IP address 192.168.128.100.  To do this:

• On a Windows PC, select Start > Program Files/Hughes/USB LAN.  If you can see this IP address, the drivers have been installed.
• On a Mac – select System Preferences > Network. If you can see this IP address, the drivers have been installed.
