Windows Dial Up Networking (DUN) for AirLink Modems
Dial-Up Networking (PPP) Configuration for Microsoft Windows
Once you have a driver for the modem installed on your computer, you can set up and configure
Dial Up Networking (DUN) to use the modem as your connection to the Internet using PPP.
Before you start, you will need:
• Administrator privileges to the computer you are configuring or access granted by an adminis-
trator on the network to add/remove devices to your computer. (Not necessary on Windows 98/
ME.)
• A wireless user account, password, and access number (obtained from your wireless service
provider). May not be required.
• Windows COM Port and modem set up for a Standard 33600 Modem (see previous section).
• No other program running on your computer that is using the same COM port (serial port) con-
figured for your modem.

window.

b. Select Create a New Connection under Network Tasks in the menu area on the left. Select
Next to start installing and configuring the DUN connection.
Caution: If you have an existing LAN connection, installing DUN for the modem
may interfere with the LAN connection. It's recommended to disconnect your
LAN connection before using a PPP connection with your AirLink modem.
Once the DUN connection is initiated, by default, it will take over as the “default
route” for network communication and specifically for Internet access. If you want
the two connections to co-exist, you will need to de-select “Use default gateway on
remote network” (described later) and use the route command in Windows to setup
routing through the modem properly. This guide does not provide information on
the route command. You may need to consult with your network administrator to
properly configure routing.
