FritzBox Reset Password

June 28, 2022

My ISP advised me to do a factory reset (load factory settings) on my router (FritzBox 7490).

The problem was that after doing this, the admin interface would request a password.

  • The documented default “admin” did not work.
  • Powering off for 1 minute (advised by the FritzBox UI) did not work - it just prompted for password again.
  • Powering off for 5 minutes (advised by ISP) did not work.

What did work:

  • Click on “Forgot Password” on the login screen
  • Unplug all cables (no DSL, no LAN)
  • Power off for 10 minutes
  • Power it up with only the power cable in

Now after powering back up, the UI prompted me to set a new password.
