FRITZ!Box Router Login (fritzbox router login)
Log in to a FRITZ!Box at fritz.box or 192.168.178.1 with the password on the sticker. WiFi change, update and reset steps.
Connect to your FRITZ!Box WiFi or cable first. The password is printed under the router and on the service card.
A FRITZ!Box from AVM is managed through a browser page at http://fritz.box or http://192.168.178.1. There is no shared default password: each box ships with its own password printed on the sticker underneath.
This guide covers the login, where to find the password, how to change your WiFi name and password, how to update FRITZ!OS, and what to do when you are locked out.
The fastest way in: tap the login button in the box at the top of this page, then sign in with the details on your router label.
How to log in to your FRITZ!Box
- Connect your phone or computer to the FRITZ!Box WiFi, or plug in a network cable.
- Open a browser and go to http://fritz.box. If it does not load, use http://192.168.178.1.
- Enter the FRITZ!Box password from the sticker, or the password you created during setup. On newer FRITZ!OS a user name like fritz1234 may be preselected.
- Click Log In. On first use, the setup wizard asks for your internet details and may ask you to choose a new password.
Keep the service card that came in the box. It holds the FRITZ!Box password and the WiFi key, which you need after a reset.
The fritz.box address is the one I try first on any FRITZ!Box that will not open.
FRITZ!Box default login details
| Item | Default | Where to find it |
|---|---|---|
| Login address | fritz.box or 192.168.178.1 | Same for nearly all models |
| User name | None, or fritz plus 4 digits | Shown on the login page |
| Password | Unique per device | Sticker under the router, service card |
| WiFi name | FRITZ!Box plus model number | Sticker under the router |
| WiFi key | 20 digit number | Sticker and service card |
ISP-branded boxes usually keep the sticker password unless the provider changed it. If the provider manages your box, their support line can confirm the login. The sticker-password detail is the one I check first on any ISP-supplied FRITZ!Box.
How to change the FRITZ!Box WiFi name and password
- Log in at fritz.box.
- Open WLAN, then Security for the password or Wireless Network for the name.
- Set encryption to WPA2 or WPA2 + WPA3, enter a new network key of at least 12 characters, and click Apply.
- Reconnect your devices with the new password.
Need a strong key? Use our WiFi Password Generator. For me, the WLAN page is where every FRITZ!Box WiFi change starts.
How to update FRITZ!OS
Updates fix security holes and add features, so keep your box current:
- Log in and open System, then Update.
- Click Check for new FRITZ!OS. If one is found, start the update.
- Do not unplug the box while it updates. It restarts on its own after a few minutes.
- Turn on automatic updates under Auto-Update so future releases install by themselves.
The Auto-Update toggle is the step I never skip on any FRITZ!Box I touch.
FRITZ!Box login problems and fixes
- fritz.box shows a search page: type http://fritz.box with http, or use 192.168.178.1.
- Page does not load at all: you may be on mobile data, a VPN or another WiFi. Connect to the FRITZ!Box directly.
- Wrong password: the sticker password works only if nobody changed it. Try the one you set during setup.
- Address was changed: connect by cable and try the emergency address 169.254.1.1.
- Completely locked out: reset to factory settings using the AVM recovery steps for your model. This erases all settings.
When a FRITZ!Box login will not work, I check the sticker before I touch anything else.
How to reset a FRITZ!Box
If you can still log in, open System, Backup, then Factory Settings and confirm. Save a backup first so you can restore your settings later. My first stop is the Backup page whenever a reset is on the table.
If you cannot log in, AVM provides model-specific recovery options, including a reset code dialed from a connected phone on many models. After a reset, the FRITZ!Box password and WiFi key on the sticker work again. See our general guide on how to reset a router for what to prepare.
Frequently Asked Questions
What is the default FRITZ!Box password?
There is no shared default. Each FRITZ!Box has its own password printed on the sticker under the router and on the service card.
What is the FRITZ!Box user name?
Older setups use only a password. Newer FRITZ!OS versions may create a user name like fritz followed by four digits, shown on the login screen.
Why does fritz.box not work?
Your device is probably not connected to the FRITZ!Box, or the browser treats fritz.box as a search. Use http://192.168.178.1 instead.
Can I log in to my FRITZ!Box from outside my home?
Yes, with MyFRITZ! or the MyFRITZ!App, once you enable remote access in the settings.
Does a FRITZ!Box reset delete my settings?
Yes. A factory reset erases WiFi, internet and phone settings. Save a backup first when you can.
