FRITZ!Box reports "Wi-Fi transmission quality increased by reduced channel bandwidth"

The following message is displayed in the event log of the FRITZ!Box:

  • "Wi-Fi transmission quality increased by reduced channel bandwidth (2.4 GHz)"

Cause

  • In environments with many other 2.4 GHz Wi-Fi networks, the FRITZ!Box automatically reduces the channel bandwidth in the 2.4 GHz Wi-Fi network from 40 MHz to 20 MHz. By temporarily reducing the channel bandwidth, Wi-Fi connections in the 2.4 GHz Wi-Fi network are disturbed less and the user data rate of the connections is increased.

Optimizing the FRITZ!Box's Wi-Fi settings

Optimize the Wi-Fi network of the FRITZ!Box so that it automatically selects the best Wi-Fi channel for the given situation and, if necessary, can steer wireless devices from the 2.4 GHz Wi-Fi network to the 5 GHz Wi-Fi network or a different wireless access point:

  1. Set up the FRITZ!Box as described in the guide Optimizing the Wi-Fi network of the FRITZ!Box.
