Driver wifi b822 Realtek

Hello everyone,

I've a problem to use my wifi card with debian on my computer.
I already post on 2 differents french forums, but they didn't succeed to solve my problem.

A bought a new computer, an Asus, and my wifi card aren't recognized by my debian OS.

I installed a new kernel: stretch backports 4.16.0
and new realtek package firmware: firmware-realtek (20170823-1~bpo9+1)
But that don't work.

That's result of an lspci command:
Code: Select all
00:00.0 Host bridge: Intel Corporation Device 5914 (rev 08)
00:02.0 VGA compatible controller: Intel Corporation Device 5917 (rev 07)

00:14.2 Signal processing controller: Intel Corporation Sunrise Point-LP Thermal subsystem (rev 21)

00:1f.0 ISA bridge: Intel Corporation Device 9d4e (rev 21)
00:1f.2 Memory controller: Intel Corporation Sunrise Point-LP PMC (rev 21)
00:1f.3 Audio device: Intel Corporation Device 9d71 (rev 21)
00:1f.4 SMBus: Intel Corporation Sunrise Point-LP SMBus (rev 21)
01:00.0 3D controller: NVIDIA Corporation Device 1d10 (rev a1)
02:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device b822



I succeed to use this wifi with a Arch-linux before, but I don't remember the kernel version that I used.

I hope you will can help me.

Sorry if my english isn't very good, I'm french :oops:

Thank you.

Julien.

This askubuntu thread suggests it works with 4.14 >>> https://askubuntu.com/questions/926364/ ... -on-ubuntu.

I WOULD NOT follow the Ubuntu instructions to install that kernel. It can be backported. Look here >>> http://jensd.be/818/linux/install-a-new ... tch-stable

Then get the firmware and install it in the location given.

Hi!

Thank you for your answer.

I cannot install the 4.14 kernel, when I search linux-image after added backport repo, I just have the possibility to install kernel 4.9 or 4.16...
Kernel 4.16 is already installed on my computer, so, i downloaded the firmware rtl8822befw.bin and copied to /lib/firmware/rtlwifi but it doesn't work... When I reboot I cannot connect my computer to wifi. :(

Now, I'm using a cellular hotspot with USB cable because I don't have ethernet connection on my computer.

Thank you for your help. :D

Julien.

...my wifi card aren't recognized by my debian OS
...


I don't understand, the card is listed in this output? Why do you say not recognized?
02:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device b822


Check dmesg, does the firmware load? Is another firmware asked for? Do you have an interface listed with ip command?

copied to /lib/firmware/rtlwifi
Did you reboot to get the wifi to work?

This page seems to indicate that the "b822" is the Bluetooth part of the chipset: https://wikidevi.com/wiki/Realtek_RTL8812BU_USB_Module
Code: Select all
0bda:b822   Realtek Bluetooth 4.0 Adapter


Do you have a wired Net connection? If so, install inxi, update your pci and usb IDs as sysadmin:

Code: Select all
update-pciids
update-usbids


Then give us the result of
Code: Select all
inxi -N


for a better hardware readout.
The MX Linux repositories: Backports galore! If we don't have something, just ask and we'll try--we like challenges. New packages: Flightgear 2018.2.2, 4.19.5 kernel, wine-staging 4.0~rc1, Pale Moon 28.2.2, Mesa 18.2.6, Midori 7.0

You "could" try another non-free firmware file opposed to using backports.

Have a look in here and see if one will work

Yeah, 220, 221. Whatever it takes.

I had a similar issue with a Realtek chipset based network adapter. As I recall the resolution I found was installing the 'linux-firmware-nonfree' package, this included the realtek drivers needed. This left me with an interesting side effect though, unless I manually connected to a network by entering in the login info as a hidden router, it would not connect to any network, just kept scanning and when I would click on a network they all reloaded and I had to select again, rinse and repeat. I finally said heck with that and got the venerable AWUS036NHA from Alfa Networks. Hope this helps and everything works out!
