Chapter in this post:
Sometimes it is necessary to reset a FritzBox to the factory settings. This means that you do a complete reset and reset all settings in the device to these data that they had on delivery.
AVM has numerous FritzBox models on the market that are equipped with the FritzBox user interface. While older FritzBox models still have a right reset button, AVM has made a change and as of the FritzBox 7490 there is no longer a hardware button that resets the box to the factory settings.
For this reason you have to use one of the methods listed below and reset the FritzBox via a tone dialing telephone or via the user interface. Below I have listed which FritzBox models have a button and which do not.
Attention: When you reset to the factory settings, of course, all of your settings will also work. This means that your Internet access data, your telephone configuration and all other settings will be completely deleted.
If you do not want this and you are still in the admin area of the FritzBox (either via http://fritz.box or via the IP 192.168.178.1), then you can create a backup of the settings this way:
Provided that you still have the password for the admin area of the FritzBox, you can also easily do the reset via this user interface. To do this, you proceed as follows:
A reader drew my attention to the fact that there is a second, so-called "emergency IP". This can also be used to access the Fritz! Box user interface if, for example, the network settings have been made incorrectly and the AVM router can no longer be reached via the usual IP address.
If you want to get the emergency IP, you can find it via this link: http://169.254.1.1
If you no longer have access to the user interface, for example because you forgot your password, you can also reset the FritzBox by phone. For this to work you need a phone that supports tone dialing. You can recognize this quickly by the fact that it generates tones when you dial. This can also be a DECT telephone that is connected to the FritzBox (if the FritzBox has a DECT module installed). Important: An IP telephone cannot be used for this purpose.
So if you have such a phone connected to the FritzBox, proceed as follows:
If you have the FritzBox back in its factory condition, you first have to reconnect to it in order to set it up. You can find the corresponding WLAN password on the underside of each FritzBox.
On the underside there is usually a sticker on which a 2-digit number code can be found under the designation "WLAN network key (WPA20)". This is the wifi password.
The factory reset deletes all the settings that the user has made, but the firmware cannot be deleted. After a firmware update, you cannot downgrade back to an old firmware.
Here is a list of the models (as of April 2013) which (to the best of my knowledge) do NOT have a hardware reset button:
All other models have a reset button that can be used to reset. For example:
