802.11 w/ airmon-ng monitor mode - channel setting for 6 GHz?
I'm running Wireshark 3.4.2 on Ubuntu 20.10 with 5.11 kernel.
The Wi-Fi NIC is Intel AX-210 with iwlwifi driver for AX-210: iwlwifi-ty-59.601f3a66.0.tgz
I'm using airmon-ng in monitor mode.
I can capture management frames, but I cannot set the channel properly.
The usage for airmon-ng is
usage: airmon-ng <start|stop> <interface> [channel]
where the channel is a channel number, not a frequency.
That works fine for 2.4 and 5 GHz bands. However the new 6 GHz band uses defines a new numbering scheme that is overlaps with lower bands. The channels are from channel 1 at 5955 MHz to channel 233 at 7115 MHz.
How is airmon-ng set configured to use the 6 GHz band?
