If you do sudo iwlist wlan0 scan freq 2412
or sudo iw wlan0 scan freq 2412
you will get a full scan and not a channel scan.
I think there maybe a bug in the RPi implementation of iw.
Has anyone had success with this function on the Pi?

After working with one of the iw dev team, he shared a command option that works every time.
Adding the "flush" option works with the RPi-3b I am using.
sudo iw scann freq 2412 flush
It does not work with a Lenovo/IBM Thinkpad I have with an old 54g WiFi card in it.
It appears there maybe a caching issue for them to address on some implementations.
