Wireless / Security / Encryption

WPA encryption is currently the most secure encryption method for your wireless LAN network and should be used whenever possible. Use a different cipher only if the wireless devices you use do not support WPA encryption.

WPA Encryption

WPA mode

The "WPA + WPA2" setting automatically uses the WPA mode most suitable for your connections. In some cases, however, it may be necessary to set a specific WPA mode for the wireless devices used and switch to "WPA2 (CCMP)".

Network key

  1. Enter in this field the network key used to secure radio connections.
  2. The network key must be between 8 and 63 characters in length. For reasons of security the network key should always be at least 20 characters long. In assigning a password, remember also to comply with the list of valid characters.
  3. Click on the "Apply" button to save your settings.

The "Wireless Access" window opens. All information required for the wireless LAN settings in the wireless devices is summarized here. You can print out these settings.

The network key assigned here must also be entered in the wireless LAN settings of the wireless adapter.

Additional Security Settings

Restricting Wireless LAN Access

With these options you define which wireless devices can connect with the FRITZ!Box:

OptionPermitted devices
Allow all new wireless devices
  • all known wireless devices
  • new wireless LAN devices
Do not allow any new wireless devices
  • all known wireless devices

New wireless devices can be introduced to the FRITZ!Box by clicking on the "Add Wireless Device" button.


The "Do not allow any new wireless devices" option does not provide sufficient protection from unauthorized use of your wireless network. To protect the network effectively, enable WPA encryption.
