Which address should I use to log in to a 1&1 router?

The default login address is fritz.box. Enter it in the address bar of your browser to open the login page. If that does not work, try 192.168.1.1 or 192.168.0.1.

What can I do if fritz.box does not open?

Confirm that your device is connected directly to the router. Check the address for typos. Restart the router and wait about 30 seconds. Disable any VPN or proxy connections. If the problem persists, look up the correct gateway address in the network settings of your device.

How do I change the Wi-Fi name (SSID)?

In the router admin panel, open the Wi-Fi settings and find the field for the network name (SSID). Enter the new name and save the changes. Your devices will find the network under the new name.

How do I make my router more secure?

Change the default admin password to something unique. Enable WPA3 or WPA2 encryption for Wi-Fi. Disable WPS if you do not use it. Keep the firmware updated. Consider hiding the SSID if you want extra privacy.

I have multiple routers — which one am I logging into?

Make sure you are connected to the specific router you want to configure. Each device on the network may have a different admin address. Check which gateway your device is currently using in the network settings.
