FRITZ!Box 6820 LTE – Service - Knowledge Base
Wireless settings cannot be changed
The FRITZ!Box's wireless settings cannot be changed. This means that you cannot save a new wireless key or disable the MAC address filter, for example. When you click "Apply", the previous settings are displayed again.
- The web browser settings are preventing a pop-up window from appearing in which the changed settings are displayed so they can be printed. The FRITZ!Box does not save the new settings for security reasons.
