[GarethHards]

i followed the steps on : https://thepihut.com/blogs/raspberry-pi-tutorials/how-to-setup-a-rtl881cu-usb-wifi-adapter-with-the-raspberry-pi-4 and in the file folder tried make and this was the result:

pi@raspberrypi:~/usbwifi $ cd rtl8821CU pi@raspberrypi:~/usbwifi/rtl8821CU $ make make ARCH=arm CROSS_COMPILE= -C /lib/modules/5.10.11-v7l+/build M=/home/pi/usbwifi/rtl8821CU modules make[1]: /lib/modules/5.10.11-v7l+/build: No such file or directory. Stop. make: [Makefile:1923: modules] Error 2 pi@raspberrypi:~/usbwifi/rtl8821CU $
