Avoiding WLAN Channels with DFS
The FRITZ!Box loses the WLAN connection in the 5-GHz
frequency band for no apparent reason.
In the 5-GHz frequency area the access point is pro-
grammed to change the channel whenever a radar source
transmits on the same channel (Dynamic Frequency Selec-
tion, DFS).
A forced channel change can be avoided by selecting in
the FRITZ!Box a channel for the 5-GHz frequency band that
does not use DFS (channels 36, 40, 44, 48).
