Changing the password for the FRITZ!Powerline network

FRITZ!Powerline devices are already protected by a unique network password in the factory settings and establish encrypted connections (128-bit AES). You can change the network password with the FRITZ!Powerline software. For this, the FRITZ!Powerline devices must be connected with each other.

Important:The new network password must be configured in each of the FRITZ!Powerline devices in the powerline network.

1 Downloading and installing the FRITZ!Powerline software

Call up download.avm.de/fritzpowerline/tools/fritzpowerline/ in your web browser.
Switch to the folder "de" or "en".
Download the FRITZ!Powerline software for the operating system of your computer.
Install the FRITZ!Powerline software on a computer that is connected via the FRITZ!Box or a network cable to a FRITZ!Powerline device.

2 Changing the network password

Plug the FRITZ!Powerline devices into outlets and wait until the Power LED, Powerline LED, or WLAN LED on each of them remains lit.
If the powerline network is not connected with the FRITZ!Box yet, use a network cable to connect a FRITZ!Powerline device directly to the computer on which the FRITZ!Powerline software is installed.
Start the FRITZ!Powerline software.
Double-click the icon of a FRITZ!Powerline device that is not connected to the computer or the FRITZ!Box.
Enter the new network password in the "New network password" field and click "OK". Use numerals and letters, and combine capitals and lower-case letters. The network password may be up to 1024 characters long.
Click "OK" when you are asked "Are you sure you want to change the network password?".
- After making the changes, click "OK".
Repeat steps 4 - 7 for all other FRITZ!Powerline devices and assign the same network password to each of them.
Finally, double-click the icon of the FRITZ!Powerline device that is connected to the computer or the FRITZ!Box and also assign it the same network password.
