When a fixed channel is set for "Alternative DFS Channel", this channel is shown
including frequency.
Four channels are required for the 80 MHz channel bandwidth in the corresponding
channel range. The channel range consists of the channel configured for "Channel" and
the three next channels.
There are only enough channels available for operation at 160 MHz if DFS is activated.
