FRITZ!Powerline 540E – Service

Wireless settings cannot be changed

FRITZ!Powerline's wireless settings cannot be changed when it is in "powerline bridge" or "LAN bridge" mode. 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. FRITZ!Powerline does not save the new settings for security reasons.
