Public bug reported:

We are observing that when connecting to a 6 GHz Wi-Fi access point
(channel 169), the nmcli tool incorrectly reports the channel as 0,
while other tools like iw dev and wpa_cli reflect the correct value.

The issue affects the accuracy of WiFi scanning, potentially leading to
incorrect channel information and difficulties in using the WiFi
network.

Repro steps:
- Power on the target
- Turn on the wifi 6GHz band network (Using WiFi7 TP BE19000)
- Set the region to US
$ sudo iw reg set US
- Scan the network using the cmd:
$ nmcli dev wifi list

Expected Result:
The channel set in the router should display in scan list

Additional comments:
After connecting to 6G WiFi, and executed the command
$ sudo iw dev
We are able to see the channel as 169,
and verified that in router page 6G AP channel is set to 169 itself.
However, when scanning 6G AP using nmcli, the channel is displaying as 0.
