5 Adjusting FRITZ!Box's Wi-Fi security settings

If the wireless device still does not establish a connection to the 
FRITZ!Box, it does not support the modern security functions used by the 
FRITZ!Box. To connect the wireless device anyway, you must adjust the 
security settings in the FRITZ!Box:
Disabling WPA3 transition mode (WPA2 + WPA3)

WPA transition mode allows simultaneous connections with WPA3 and WPA2 
encryption using the same Wi-Fi network name and network key. With 
connections with WPA2 encryption, however, WPA3 transition mode has 
higher security requirements than usual for WPA2 (CCMP).

Some wireless devices cannot establish a Wi-Fi connection if WPA3 
transition mode is enabled. This is the case with iPhones and iPads with 
iOS older than 12.1.1, older wireless printers, IP cameras, and wireless 
plugs, for example:
