OrangePi Lite can't find ap via wifi

[Wronnay]

Hello,

 

i've got a problem with my orangepi lite.

 

Here are a few posts about problems with connecting to wifi networks, but my device can't even find wifi networks (with

iwlist wlan0 scan

). In my area are multiple access point active.

 

The OS is armbian for OrangePi Lite Version: 5.20.

iwconfig

shows the chip with no errors.

 

I have tried multiple settings in /etc/network/interfaces and  /etc/wpa_supplicant/wpa_supplicant.conf after posts in this forum but nothing is working ...

Sorry, I really can't/want help with these anachronistic methods unfortunately everyone uses since tutorials/forums are the result of copy&paste of outdated stuff. I can only report that it was with such an OPi Lite that I enjoyed Wi-Fi on Linux the first time in my life: https://github.com/igorpecovnik/lib/issues/493#issuecomment-252751466

does it find absolutely no networks or only not your network?

 

In my case with a RPi 3 it fond all other networks even outer mine. After some search I found out that it could not show channels 12 and 13 because of of country settings etc. I had to patch something because setting the country didnt work.

 

Make sure that the wanted ap's are in range of 1-11

 

Greetings

With most recent Armbian builds this should be resolved by using the appropriate mechanism(s): either /etc/default/crda or /etc/NetworkManager/dispatcher.d/pre-up.d/

 

Unfortunately not every driver seems to support this: The following is a NanoPi Air directly after boot and logged in through wlan0:

So setting regulatory domain doesn't work (at least on NanoPi Air) but joining channel 13 does. But as already written, forget about this anachronistic stuff, use nmcli and nmtui instead
