Configuring a Speedstream 4100 or 5100 DSL Modem

These instructions are for configuring a Speedstream 4100 modem or a Speedstream 5100 modem to work with Cruzio DSL. In addition to the modem, you will need its power cord, an ethernet cable, and a phone cable.

If you bought your Speedstream modem from Cruzio, it should already be pre-configured to work with Cruzio DSL, and you should not need these instructions.

  1. Plug the power cord into the back of the modem and into a wall outlet. Plug one end of the phone cable into the DSL port at the back of the modem, and the other end into a phone jack. Plug the ethernet cable into the remaining port in the modem, and attach the other end of the cable into your computer. Finally, turn on the modem by pressing the only button on the modem.
  2. Watch the lights on the modem and wait for the Power and the Ethernet light to turn a solid green. If they do so, open the web browser of your choice.

    If you bought your modem used, it may already be configured to work with a Cruzio connection. Try visiting a few websites. If you are able to reach them, you’re done! However, if the browser fails to load any web pages, continue to the next step.

  3. In your browser’s address bar, enter, and then press the Enter or Return key.
  4. Depending on your modem, it may ask you for a Modem Access Code. If it does, your Access Code is located on a yellow sticker on the bottom of your modem. Type it in and click Continue.
  5. On the Configuration screen, you will see some blue buttons on the left. Click the Advanced button.
  6. Several grey buttons will appear beneath the blue buttons. Click the PPP Location button.
  7. The modem may ask you for the Modem Access Code again. If it does, enter it again and click Continue.
  8. The screen will offer you three options. Select the last option labeled “Bridged Mode (PPPoE is not used)”. At the bottom of the screen, click Save Changes.
  9. Depending on your modem, a PPP Location Warning page might come up now. If it does, click Change PPP Location, and then click Restart.
  10. Now wait for your modem to restart. Watch the modem’s lights and wait for the Power, DSL and Ethernet lights to go solid green. When they do so, open your Web browser and try visiting a few websites. If they load, congratulations! Your modem is now properly configured for your Cruzio DSL.

If you are still unable to surf the Web, or if the Power, DSL, or Ethernet lights keep blinking after several minutes when these instructions say they should turn solid, please contact Cruzio Technical Support.
