Have you tried to login to the EnGenius ESR9850 router and been unsuccessful? You may need to reset the EnGenius ESR9850 router back to the original factory defaults.

This is not the same thing as a reboot. When you reboot a router you cycle the power to the unit. When you reset the router you take any setting that has been changed and return them all to how they were from the factory.

Warning: Resetting the EnGenius ESR9850 router is a big step and should not be taken lightly. Things you need to consider before continuing are:

  • The router's interface username and password are erased and reverted back to factory defaults.
  • The WiFi information such as the network name and password.
  • If this is a DSL router you need to re-enter the ISP or Internet Service Provider username and password. Call your local ISP for the details.
  • Have you ever made any other changes such as port forwards or IP address changes? These will need to be reconfigured as well.

Reset the EnGenius ESR9850

The very first thing to do is to find the reset button on the outside of the device. For the EnGenius ESR9850 router you can find it on the back panel. I have circled it's location for you in the image below.

This is the reset page from your EnGenius ESR9850 router.

While the router is on, take a straightened paperclip and press down on the reset button for about 10 seconds. This begins the reset process. If you don't hold this button down long enough you end up only rebooting the device instead of resetting it like you wanted.

Remember a reset like this one is going to erase every single setting you have ever changed. We recommend trying other methods of troubleshooting before you continue.

Login to the EnGenius ESR9850

Once you've reset the EnGenius ESR9850 router you should log into it. This is done by using the factory default username and password. Don't know where to find these? We have them provided for your use in our Login Guide.

Tip: If the defaults aren't logging you in it might be because the reset button wasn't held down for long enough.

Change Your Password

After you've reset and logged into your router we recommend setting a new password for it. This can be anything you want it to be, however keep in mind that a strong password contains no personal information and is 14-20 characters in length. For more help be sure to visit our Choosing a Strong Password Guide.

Tip: Avoid losing your new password by writing it on a sticky note and attaching it to the bottom of your router.
