I’ve loaded the 2.041-2016-12-12-pi img onto a Raspberry Pi 3. When I try to add my SSID from the available wireless networks list, I don’t see it listed, but using various wifi scanner apps I know its up and available on the 2.4GHz band.
I then ran a terminal session and ran a “iwlist wlan0 scan” command and again the SSID isn’t showing up, but i only see SSID’s for channels 1-9.
However if run up a different OS image on a different SD card using the latest Raspbian Jessie image on the same Pi3, and run the same “iwlist wlan0 scan” command, i do see my routers wireless SSID showing on channel 13?
I could try and change the channel used on the router to confirm this but wondering if this is a known issue for this OS image level ?
