How do I activate the TR064 interface on my Fritz!Box?
TR-064 is activated on FRITZ!Box devices from FRITZ!OS 5.5x onwards when delivered. This is also the case for devices provided by Internet providers such as UnityMedia, KabelBW, 1&1, etc.
If TR-064 is not active, this can be easily changed via the FRITZ!Box user interface:
To do this, open the Fritz!Box user interface by entering “http://fritz.box” in your Internet browser
Navigate to Home Network > Home Network Overview (or Network) > Network Settings
Under Home Network Shares you will find the option “Allow access for applications“
Activate the checkbox next to the option “Allow access for applications”
Restart your Fritz!Box. Only then will the change become active
If the option is not present, you cannot activate TR064 on this Fritz!Box.
