On this page we show you how to reset the Buffalo WZR-D1800H router. This isn't the same thing as a reboot which is only cycling the power to the device. A reset takes all the settings and returns every one of them back to factory settings.

Warning: Resetting this router is a big step. Make sure you understand what is changed. We have started a list of some of the changes.

  1. The router username and password
  2. The Internet name and password
  3. The ISP username and password if you use DSL. You have to call your local ISP for this information.
  4. Write down any other changes you have made to this router such as DNS servers or IP assignments.
