This guide shows you how to reset your Motorola SB6121 router to factory default settings. This is not the same thing as rebooting a router. Turning a router off and back on again causes a reboot. This is very different from a reset, which erases a router completely and returns it to factory default settings.
Warning: Make sure that you fully understand the following before resetting your router. The following settings in your router will be changed:
- The router's username and password are reset to factory defaults.
- All WiFi login information and network names are reset.
- Your ISP settings are reset, which means you will have to contact your ISP to get them back.
- Any firewall settings, parental controls, and port forwards that you have configured will be removed.
A router reset is the last step you should take in recovering your router's password. You should be sure that you have tried to at least recover your router password using our Router Password Finder before resorting to a router reset.

A router reset should be the last thing you try if you are unable to login.
Reset the Motorola SB6121
There is usually a small reset button located on either the back or the bottom of a router. Look for something that looks like this:
Even though yours may look slightly different, you need to look for a tiny button. You might find a pinhole on the back of the router that requires a paper clip to push the button hidden under it.
Hold the reset button down for 10 seconds and watch the lights. The lights on the front of the router should do something different when the reset happens. Do not be concerned about holding the reset button down too long. It will not hurt anything.
Remember, this will erase everything you have previously done to this Motorola SB6121 router.
Be sure to only reset your router if you have tried everything else, such as running our Router Password Finder software, which can find your lost or forgotten router password for you.
Login to the Motorola SB6121
Once the reset is complete, you need to login to your router using the default IP address, username, and password. You can follow the SB6121 Login Guide to find everything that you need to log in.
Change Your Password
Be sure to change your router's default password after you get logged back in. Leaving a router password set to default is a very serious security risk. Our Choosing a Strong Password guide can help you pick a strong password for your router.
Tip: After creating this new password, we highly recommend writing this down on a post-it note and attaching it to the bottom of your router for future reference.
