advice on how to install driver rtl8822bu

Unread post by kappahd » Tue Jan 15, 2019 12:20 am

Can anyone give me some advice on how to install these drivers easily?

I found a driver page but look complicated ;(

HardKernel has a habit of not providing (working) Kernel Headers packages.. If you're not bound to Ubuntu, you can always use Debian Jessie/Stretch, or DietPi as they have working Kernel and Header packages.
It "should" work with Ubuntu from HardKernel as well, but you probably have to create your own links to wherever HardKernel has copied their Header files, as their "linux-odroid" package includes Kernel and Header files together, but dkms files of cause won't find it directly as it's not the way the system expect headers to be.
It might also work with Armbian, but I have no info about that.

well I''m not sure what Debian you're using, the above error showed something about Kernel 4.9.103, which is not used by HardKernel or me, only Kernel 4.14 and 3.10 are supported.
If you can please try the following image: viewtopic.php?f=96&t=30552

I've just installed this. Awesome work! If I need the wifi drivers, do I need to do setup-odroid? or is that only for gui (im running headless)

The DKMS module you're using has no config for armhf.
You can try to set the ARCH upfront:

ARCH=arm dkms build -m rtl88x2bu -v ${VER}

Also Kernel 4.14.28 is rather old, you probably should update the system before that.

I think you should use wpa_supplicant to configure your wifi adapter, or install "iw" to have iwconfig.

That is not true since we released 18.04 image several months ago. :D
I had a chance to play with a unknown WiFi dongle on XU4 Ubuntu 18.04 last night.
It has a strange RTL8821CU chipset which supports 11AC 2.4GHz/5GHz dual band with Bluetooth 4.x together.

Code: Select all

odroid@odroid:~$ uname -a
Linux odroid 4.14.87-153 #1 SMP PREEMPT Tue Dec 11 11:33:18 -02 2018 armv7l
odroid@odroid:~$ lsusb
Bus 003 Device 004: ID 0bda:1a2b Realtek Semiconductor Corp. 
I had to switch the device USB mode to a network mode from a storage mode.

Code: Select all

sudo usb_modeswitch -KW -v 0bda -p 1a2b 
odroid@odroid:~$ lsusb
Bus 003 Device 005: ID 0bda:c820 Realtek Semiconductor Corp.
Device ID had changed to 1a2b to c820 by auto-re-enumeration.

And just ran the following commands to build a proper driver.

Code: Select all

git clone --depth 1 https://github.com/whitebatman2/rtl8821CU.git
cd rtl8821CU/
touch Makefile
make -j8
sudo make install
sudo modprobe 8821cu
I could connect to some 5G and 2.4G APs with iw command.
DKMS module also could compile and worked nicely too.
Bluetooth worked well.

Actually it's still true, you don't deliver linux-header packages, you have a linux-odroid package that has headers inside.
Something like apt install linux-headers-$(uname -r) still fails on the Ubuntu image.
But yes, you have the headers itself available on the image now and in most cases this should be enough.

Have you tested if it automatically triggers a rebuild of a DKMS modules each time a new Kernel is installed, as it is the case when you install/update a linux-header package?

Have you installed the realtek firmware package? Maybe it's simply missing the firmware for the WLAN Module.
Can you check the output of dmesg | grep -i firmware

Why did you add the -D rtl88x2bu? Normally you don't need to explicitly hand over the driver the system is suppose to use.
It should find the driver automatically. try without the -D option.
Have you configured your /etc/wpa_supplicant.conf already?
Also as I said if you're more familiar with iwconfig you can install "iw" apt install iw and use iwconfig instead.

HardKernel has a habit of not providing (working) Kernel Headers packages..
That is not true since we released 18.04 image several months ago. :D
I had a chance to play with a unknown WiFi dongle on XU4 Ubuntu 18.04 last night.
It has a strange RTL8821CU chipset which supports 11AC 2.4GHz/5GHz dual band with Bluetooth 4.x together.

Code: Select all

odroid@odroid:~$ uname -a
Linux odroid 4.14.87-153 #1 SMP PREEMPT Tue Dec 11 11:33:18 -02 2018 armv7l
odroid@odroid:~$ lsusb
Bus 003 Device 004: ID 0bda:1a2b Realtek Semiconductor Corp. 
I had to switch the device USB mode to a network mode from a storage mode.

Code: Select all

sudo usb_modeswitch -KW -v 0bda -p 1a2b 
odroid@odroid:~$ lsusb
Bus 003 Device 005: ID 0bda:c820 Realtek Semiconductor Corp.
Device ID had changed to 1a2b to c820 by auto-re-enumeration.

And just ran the following commands to build a proper driver.

Code: Select all

git clone --depth 1 https://github.com/whitebatman2/rtl8821CU.git
cd rtl8821CU/
touch Makefile
make -j8
sudo make install
sudo modprobe 8821cu
I could connect to some 5G and 2.4G APs with iw command.
DKMS module also could compile and worked nicely too.
Bluetooth worked well.
What commands did you use to connect to wifi? I keep getting hanged :(
