192.168.178.1 Login: Access Your FRITZ!Box Admin Panel

The IP address 192.168.178.1 is the default admin gateway for the AVM FRITZ!Box, by far the most common home router in Germany. Unlike most routers, a FRITZ!Box does not use admin/admin or any shared default. Each one ships with its own unique password printed on the device. This guide shows you where to find that password, how to log in, and how to fix the issues that come up most often.

What Is 192.168.178.1?

192.168.178.1 is a private IP address, which means it works only inside your own network and cannot be reached from the public internet. Your FRITZ!Box uses it as the address for its admin interface, the page where you change your Wi-Fi name and password, manage connected devices, set up the telephone features, and update the firmware.

AVM also gives the box a friendly name, so you can reach the same interface by typing fritz.box in your browser instead of the numeric address. Both go to the same place. If one ever fails to load, the other is the first thing to try.

How to Log In to Your FRITZ!Box at 192.168.178.1

1. Connect your phone or computer to the FRITZ!Box, over Wi-Fi or with a LAN cable. A wired connection is steadier while you change settings, since adjusting the Wi-Fi will not drop your session.
2. Open a web browser such as Chrome, Firefox, Edge, or Safari.
3. Click the address bar at the top of the browser, the bar that shows the web address. Do not use the search box in the middle of the page.
4. Type 192.168.178.1 or fritz.box and press Enter. Use digits only in the numeric address.
5. Wait for the login page. If the browser warns the connection is not private, click “Advanced” and proceed. The FRITZ!Box uses a self-signed certificate that triggers this, and it is safe on your own network.
6. Enter the FRITZ!Box password. On most models there is no username field, just a single password box.
7. Click “Anmelden” (Log In) to reach the interface.

Where to Find Your FRITZ!Box Password

This is the part that surprises people coming from other router brands. A FRITZ!Box is not protected by admin/admin or 1234. Each unit is assigned a unique password at the factory, and it is printed on a label on the underside of the device.

On a German unit the label reads FRITZ!Box-Kennwort. On an international English unit it reads FRITZ!Box Password. The value is usually two short words and a number, for example “etappe 2535”. Type it exactly as shown, including the space if there is one.

Model / Version	Username	Password
FRITZ!Box (German label)	(leave blank)	the FRITZ!Box-Kennwort on the label
FRITZ!Box (English label)	(leave blank)	the FRITZ!Box Password on the label
Older FRITZ!Box models	admin	admin (only if no label password exists)

If the printed password does not work, it has been changed since the box was set up. The only way back in then is a factory reset, covered below.

Some newer models prompt you to create your own password the first time you log in. If that happened during setup, use the password you chose, not the one on the label.

What to Do If You Cannot Log In

The page will not load. Confirm 192.168.178.1 is actually your gateway. If you have a separate modem or a changed configuration, it may be different.

• On Windows: press Windows + R, type cmd, and in the window type ipconfig. Read the “Default Gateway” line.
• On Mac: open Terminal and type netstat -nr | grep default.
• On Android or iOS: open Wi-Fi settings, tap the connected network, and look for the gateway or router field.

You can also just try fritz.box, which works even if the numeric address has been changed.

You typed a letter instead of a number

The most common mistake is “192.168.l78.1” with the letter L in place of the first number one. That is not a valid address and the browser treats it as a search. Retype it carefully as 192.168.178.1, or use fritz.box to avoid the issue entirely.

You got search results

That means the address went into a search engine, not the browser’s address bar. Click the bar at the very top of the window, clear it, type fritz.box, and press Enter.

The password is rejected

Check that you are reading the label correctly. The FRITZ!Box-Kennwort can mix similar-looking characters, and it is case-sensitive. If you set your own password during setup, use that one instead. If neither works, a factory reset is the next step.

You are not connected to the FRITZ!Box

The address only resolves when your device is on the FRITZ!Box network. If your phone slipped to mobile data or another Wi-Fi, the page will not open. Reconnect first.

How to Reset Your FRITZ!Box to Factory Settings

A factory reset erases everything: your Wi-Fi name and key, the telephone settings, any custom configuration, and your login password. The box returns to how it shipped, so reset only when you are locked out and have no other way in.

1. With the FRITZ!Box powered on, find the reset option. The simplest universal method is the recessed reset access on the device.
2. Press and hold the reset access for about 15 seconds using a pointed object, until the LEDs flash.
3. Release and wait one to two minutes for the box to reboot fully.
4. Log in again at 192.168.178.1 using the FRITZ!Box-Kennwort printed on the device label.
5. Run through the setup wizard to restore your internet connection and Wi-Fi.

A caution worth noting: if your internet provider pre-configured the FRITZ!Box, a reset can clear the connection settings. If the internet does not return after the reset, you may need your provider’s access data, which is often included in your contract documents, or a call to their support line.

How to Change Your Wi-Fi Password on a FRITZ!Box

Changing the Wi-Fi key on a FRITZ!Box is quick once you are logged in.

1. Log in at fritz.box or 192.168.178.1.
2. In the menu, open WLAN (Wireless), then Sicherheit (Security).
3. Find the Netzwerkschluessel (network key) field and enter your new Wi-Fi password.
4. Set the encryption to WPA2 (CCMP) or WPA3 if your devices support it.
5. Click Uebernehmen (Apply) to save.

After saving, every device drops off the Wi-Fi and has to reconnect using the new key. To change the network name instead, open WLAN then Funknetz (Radio Network) and edit the SSID. Choose a Wi-Fi password of at least 12 characters with no personal details.

Conclusion

The one thing to remember with a FRITZ!Box is that it does not use admin/admin like other routers. Your password is the unique FRITZ!Box-Kennwort on the underside of the device, and fritz.box is an easier way to reach the login page than the numeric address. Once you are in, set a Wi-Fi key you control and, if you like, your own login password under the System menu, so you are not relying on the printed default.
