Orange Pi 5 - RTL8821CU device driver for Debian or Ubuntu

OrangeDruid

Hi All,

I have an USB Wifi & Bluetooth dongle with RTL8821CU chip, just like this:
https://www.amazon.com/Bluetooth ... %2Caps%2C187&sr=8-3

When I attempt to build and install the driver I need to install the kernel headers,
however the kernel headers are not available for RK3588 Debian or Ubuntu.

I'm trying to install the driver from here:
https://github.com/morrownr/8821cu-20210118/blob/main/README.md

This is the terminal command which fails to install the kernel headers:
sudo apt install -y linux-headers-($uname -r)
You can verify the failure to install the kernel headers from any Orange Pi 5
running Debian or Ubuntu by executing the command above.

How can I install the kernel headers in order to build custom drivers?

I'm just trying to get the USB Wifi & Bluetooth dongle with RTL8821CU chip to work,
so if there is a simpler, easier way to achieve that which does not involve installing kernel
headers and building a custom driver then that would be first prize!

Any help would be sincerely appreciated

All the best,
Brendon

P.S. - While attempting to install the kernel headers and the device driver my Orange Pi 5
is connected to the internet via an Ethernet cable and I can successfully access the
internet through the web browser from the Orange Pi 5.

Hi People,

I have one Dual Band USB Adapter "WiFi 5" working pretty good and very fast for DEBIAN and UBUNTU, and not working for droid,

Its a Realtek AC1200 Mbps and "lsusb" says it is:  

Bus 001 Device 005: ID 0bda:b812 Realtek Semiconductor Corp. RTL88x2bu [AC1200 Techkey]

With some dongles and modules, driver support will be determined by the kernel used, which is quite old now with the Rockchip 5.1 version.

I have one dongle which required 5.8.

Quite possibly some good news.

It seems that a user that has purchased a WiFi/BT dongle based upon the RTL8821CU chipset has it working in both Linux and Android.

Absolute confirmation is awaited but the signs seem positive.

After these steps, it's recommended to reboot your system to ensure that the newly installed driver is loaded correctly.

Compile and install the driver from source: Download the latest driver source code from Realtek. Extract, configure, Vampire Survivors and make. Install the compiled module. May require dependencies like build-essential.

Rebooting your computer after completing these steps will guarantee that the freshly installed driver is loaded properly. tunnel rush
