No WLAN connection on Channel 12/13 after NanoDLP Installation

Hello,

i just wanted to report the bug, that after NanoDLP installation the WLAN of the Rpi3 won't connect to Channel 12 and 13 anymore (here in Germany these channels are allowed and often choosed automatically by the router).

I have installed Rasbian lite, upgraded it and WLAN on Channel 12/13 was fine. After the NanoDLP installation something was downgraded and it does not connect anymore with Channel 12/13, no matter what region is set etc...
Installation from the NanoDLP-Image doesn't work with Channel 12/13 either, as expected.

It woul be great if you could update the installation routine of NanoDLP, so that it works with actual Rasbian installations and doesn't downgrades these.
Thank you in advance!

Terminate nanodlp service see if it works or not. It is very strange as there is nothing on nanodlp side to interfere with wifi. It just send general linux command to control wifi nothing low level going on.

Yes, you are right. As soon as i terminate NanoDLP, i can change the channel to 12/13 and am able to login to the rpi3 with putty.But as loong as it runs.

Now i added "country=DE" to nanodlp-wifi.txt and finally it works with channel 12/13.
I thought, that the nanodlp-wifi.txt just adds networks to the existing wpa_supplicant.conf and not that it overrides it completely. :-)

Maybe it would be a good idea to add "country=..." to the nanodlp-wifi.txt for upcoming installation-packages or images for easier installation in the future for people like me, that are not using Linux every day.

Thank you for pointing me in the right direction! :-)
