Manual Modem Settings
The Optus DSL Broadband self-installation CD configures all the necessary settings for your DSL Broadband service. You do not need to manually configure your modem if you have run the self-installation CD. While the following information is provided for your reference, using the self-installation CD is the recommended method for configuring your modem.
The Siemens SpeedStream 4200 ADSL modem can use either
USB or
Ethernet to connect to your computer.
- If you are connecting via USB you will need to run the self-installation CD to install the USB driver before you connect your modem. The Siemens SpeedStream 4200 ADSL modem supplied by Optus has been customised for the Optus DSL Broadband service. Only the USB driver supplied on the self-installation CD will work with the Optus service. If you do not have the self-installation CD, you can download the latest drivers from the Siemens website.
- If you are connecting via Ethernet it is possible to manually configure your modem without the self-installation CD. Only a web browser is required.
After connecting your modem there are two key steps to manually configure your modem for the Optus DSL Broadband service:
- PC settings - Configure your computer's Ethernet network interface.
- Configure Your Modem - Set the password in your modem's configuration pages.
