How to Unlock a Motorola SB5101


The Motorola SB5101 cable modem is a high-speed Internet modem that can be used in conjunction with a wireless router to deliver a high-speed wireless Internet connection. While the modem handles the Internet connection itself, your router of choice handles the security associated with the modem. If you have your Motorola SB5101 connected to a wireless router and the connection is locked, you and anyone else that wants to connect to the wireless access point will be unable to do so without knowing the router's passcode. If you unlock the device, however, you access the router's connection without entering a passcode first. You can unlock the connection on your Motorola SB5101 by navigating to your router's settings page and disabling its security settings.

Things You'll Need

  • Ethernet cable
  • Plug one end of the Ethernet cable into the Ethernet port on your computer. Plug the opposite end of the Ethernet cable into the output Ethernet port on the back of the router.

  • Open a Web browser and enter the router's default IP address into the browser's address bar. On many routers, this IP address is "," "" or "," but the address may vary. See the documentation that came with your device for specific details. You may or may not have to precede the IP address with "http://"

  • Press the "Enter" key to navigate to the router's setup page. Follow onscreen instructions to type the user name and password in the space provided and click the "Submit" or "OK" button to log into the router. The exact procedure will vary according to your individual router.

  • Look for an option named "Security" or something similar. Security is typically listed under the "Wireless" heading. Look for an option to check "Disabled," "None" or something equivalent. The exact layout will vary according to your individual router.

  • Click "Apply" or "Save" to save the changes. The Motorola SB5101's Internet connection will now be unlocked.

Tips & Warnings

  • The exact options listed and the layout on your router's setup screen will depend on your specific router.
  • Disabling the security settings on your router exposes your router to unauthorized users and allows them to connect to your network.
