Recommended Posts

Hello, I have a usb wifi device which works well on nano pi neo 3.4.113-sun8i.

I update to the latest ditribution 5.15.48-sunxi jammy, then I rebuild kernel drivers but now it only work on a cold boot and when I hot plug the adapter.

On a warm boot the adapter with lsusb is ok but nmcli can't find the device.

I have the same problem with another usb wifi adapter (lsmod is ok, but stil not working with "rmmod 8821cu" and then "modprobe 8821cu")
