All problems with Wi-Fi due to the fact that it is turned off in the kernel!
Check the config in the /boot/ folder - must be enabled: "Device Drivers - Network Device Support - Wireless LAN - Unisoc wireless Support - UNISOC WCN Device Drivers(for new chip...) - allwinner board Support for uwe5622"
and may need "UWE5622 Wi-Fi Driver"
After that, the wifi appears among the "iw dev" devices, otherwise it is not there.
