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 ...
