Hi! I've been dealing with this error for the past two days and finally managed to solve it. I'll try to guide everyone through the steps, but consider I'm pretty new to kali/linux so some steps might be unnecesary or even changed to fit your own system.
I installed Kali and wifi worked perfectly until I did a dist-upgrade. The only reason I did it was because it was recommended by kali documentation when trying to install nvidia drivers. After getting kernel 5.2.0 wifi was gone, not even detected in iwconfig, but my device was listed using;


lshw -C network

I followed the instructions on https://github.com/lwfinger/rtlwifi_new to install the drivers for rtl8822be, and then it was kinda detected, it was showing on my network manager but not finding any networks. It was now listed in iwfconfig under the DISABLED flag (or something like that).
In order to be as precise as I can regarding to what I did, I must say I tried to uninstall these drivers (make uninstall etc...), removing them from the modules list, though they popped in again on every reboot.
So, at this point I started checking the logs and found out 3 things:
1. On every system startup i had an Error regarding network devices not being able to raise or something like that.
2. On the logs i had a halmac_init_hal failed error. But looking for that and trying out solutions didn't actually solve anything.
3. I found an error regarding a firmware not being able to load. It was pointing to rtw88/rtw8822b_fw.bin

My final step was to copy the lwfinger firmware I already had in /lib/firmware/rtlwifi/rtl8822befw.bin to the address pointed by the error. The I did a reboot and the error from the startup was gone, but I still couldnt find any networks. Installing wicd did the final trick and everything is working (although if someone has any info about how to fix it in network manager would be great, as I dont want to use wicd unless its necessary or I know what's the real difference).

This, as you can see, is my first post, so I'm sorry if I'm missing any guidelines about proper formatting or whatever.

[when123]

I was backed to 4.19 , , copy the images 5.2.0 to another folder . and grub-mkconfig to generate the new grub .
I found that , this problem not only happen in kali , but also in ubuntu which use linux kernel 5.2.0 . it
couldnt find any networks.

Hi,

I have had various issues with my wireless internal adapter Realtek RTL8822BE on my HP-X360 Laptop. I know it works because I have installed multiple distros and sometimes the drivers are there and it works and other times its not. I have had no luck getting the wifi drivers to work.

So far I was able to get the wifi to show up by following this method

You will need to install "make", "gcc", "kernel headers", "kernel build essentials", and "git".

If you are running Ubuntu, then

sudo apt-get install linux-headers-generic build-essential git

Please note the first paragraph above.

For all distros:
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
git checkout origin/extended -b extended
sudo make install
sudo modprobe -r rtl8822be


depmod -a

update-initramfs -u

reboot


After the reboot, the wifi shows up, but now it has no networks displayed. I also see that it states the network is down, but if I try bring it up (ip link set dev wlan0 up) it gives me a message

root@hpx360:~# ip link set dev wlan0 up
RTNETLINK answers: Operation not permitted

The kernel used is 5.2.0-kali2-amd64.

I have made some progress, but need a little extra help if anyone here can assist me with this matter I would greatly appreciate it.

Thank you

Any updates? Did you finally fix it, If so, how?

I have same problem

GNU bash, version 5.0.3(1)-release (x86_64-pc-linux-gnu)

Anyone have news?

Thanks in advanced

[cicloide2]

Hello, it happened to me the same, after doing an upgrade to kernel 5.2, my RT3070 Wi-Fi adapter stopped working any advice from developers and users? Thank you.

[cicloide2]

Friends this left me the adapter RT3070 Nisuta at 89% stable, the only problem is that in monitor mode it scans but does not see networks

I had the same problem once but different cause check NetworkManager file make sure it says =managed for your device not =unmanaged that's what my problem was. Hope it helps.

[raushnn]

I'm facing same problem, I installed rtl88be driver and before installing driver in "lshw -c network" command there was network unclaimed but after installing driver it's saying network disabled. and I can see my wifi option but it's saying device not ready. what does that mean ?

sorry I'm new here and i don't know how to put command separately and all

Hi
After I adding the rtl8822befw.bin file to the directory, I executed this command in terminal.
sudo apt-get install -d --reinstall network-manager network-manager-gnome

By just executing above command, wifi manager shows all the available ssids and I could connect to my network as usual. I assume by reinstalling network manager it sets to it's default settings.

Hope this will help.

What is this befw.bin file?

Where did you get it from and where exactly did you copy it to?

Thanks mate

Here?s how to solve the wifi problem:
This is how it works on ParrotOS 4.7 with latest 5.3 kernel.
This should also work for Kali Linux 2019.4 with latest kernel.

I also managed to get the TX-power to 30db. I will post instructions later today.



Ok, one way to get it running is this:


From clean ParrotOS 4.7 with all updates loaded:


go to /lib/firmware/
here you will need to create a folder named rtw88
go to /lib/firmware/rtlwifi/
here you will need to copy the file rtl8822befw.bin
go to /lib/firmware/rtw88/
here you will need to insert the file you just copied (rtl8822befw.bin)
now you will need to rename the file to rtw8822b_fw.bin
reboot your system


Now your network manager should be able use your rtl8822be wifi adapter without any problems.


Right now my ParrotOS has two bluetooth symbols in the task line but wifi is working.

Now I will try to correct the bluetooth.

I?ll let keep you up to date.

Here?s how to solve the wifi problem with latest 5.3 kernels:


rtl8822be also supports fully working monitor mode now!

Alright, bluetooth problem seems to be solved by just rebooting twice.
After two reboots my ParrotOS only shows one bluetooth symbol in the task line.


You might need to turn bluetooth on and off before or after rebooting to get rid of the second bluetooth symbol.
I actually played around with on and off a little bit and then just rebooted again.


Now the bluetooth seems to work and only shows up once.


TX-power adjustment How-To will follow later on today.

[when123]

tried all above methods , but all not workable for me . Are there any method can workable for me ?

[when123]

solved. finally worked ,
Linux ubt 5.4.0-kali3-amd64 #1 SMP Debian 5.4.13-1kali1 (2020-01-20) x86_64 GNU/Linux

GUYS I DO NOT GET YOUR PROBLEM,

I WROTE YOU 2 TIMES IN 2 DIFFERENT COLORS HOW IT WORKS WITHIN 2 MINUTES xD

I just tried this method myself again on Kali 2020.1 and it works perfectly.

Read my post carefully and do exactly what I tell you and you will be happy with your realtek rtl8822be.

If you are using Kali 2020.1 you will have to do these steps in terminal (create folder, copy file, rename file). I will not tell you the terminal commands for doing this in terminal now.

Just google and the job is done.

This method worked till the last kali update but the latest one not detecting any network now.
Is there any proper solution for this? Why this driver is not included in kali linux?

[Thiviyan]

this is the working solution.
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
git checkout extended
make
sudo make install
sudo modprobe -r rtl8822
sudo modprobe rtl8822

At this point, do a complete shutdown! The device may retain the old setting with a warm reboot.
To be safe, do a power off. After the system come back up, your WiFi and Bluetooth working now.

[H00l13C4l]

this is the working solution.
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
git checkout extended
make
sudo make install
sudo modprobe -r rtl8822
sudo modprobe rtl8822

At this point, do a complete shutdown! The device may retain the old setting with a warm reboot.
To be safe, do a power off. After the system come back up, your WiFi and Bluetooth working now.

I did this, after the system came back The pc is connected to the internet for a few seconds and then I get a system pop up saying Network Activation failed.

Any ideas why is this happening?

[hungnc6969]

My thinkpad t470 with newest kali 2020.2 also get this problem. But this not solved. It still not have WIFI on Kali.


this is the working solution.
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
git checkout extended
make
sudo make install
sudo modprobe -r rtl8822
sudo modprobe rtl8822

[Thiviyan]

i had problems with the latest kali update and i got my WiFi working after doing this.
for this you will need internet so just connect an external WiFi adapter or use Ethernet connection to fix this issue
git clone https://github.com/lwfinger/rtlwifi_new.git -b rtw88
cd rtlwifi_new
make
sudo make install
sudo modprobe -r rtw_8822be
sudo modprobe rtw_8822be

do a complete shutdown and turn on (not just restart) this will get your WiFi back

[yosef]

When I updated kali I also had problems connecting to the internet so I go to the
1 - / etc / network /
2 - open the file "interfaces"
3 - type the following:
auto eth0
iface eth0 inet dhcp

4 - reboot the system

and everything is working fine now.

[khunveasna]

Hi mate, does RTL8822BE support airepaly-ng injection?
Your driver working fine and fast responded from Internet, but aireplay-ng --test <interface> still failed(no answers).

kali@kali:~$ sudo aireplay-ng --test wlan0
[sudo] password for kali:

RTL8822BE dose not work out of the box. i am always facing issues whenever i upgrade my kernel. rtlwifi by lwfinger is the only driver gets constant updates but ye injections dont work...

How to increase TX-POWER to 30dbm and my wifi card's also changes everytime i insert it

[papa whisky]

Does anyone know how I would build this into a live-usb without using persistence. The slowdown is really annoying to deal with and I have just been rebuilding it often to limit it.

[CaptainJoe]

Dear Steve Ocean,

Thank you so much a method that finally works. I had a little laugh earlier because I found a person in here who had the exact same computer and problem I had, only to realize it was actually me who wrote it HAHA.When I came across your instructions, it seemed different to what I had read before, and you stated it worked so I thought I would give it a try. I also like that you detailed the steps in a clear, easy to read manner.

I wanted to try the new updated copy of Kali-Linux again because I recently graduated with my Bachelors in IT and Cybersecurity so I wanted to refresh myself on the tools available again, and believe or not the wifi was not showing up. I remember having this problem on multiple distro's. I have yet to find a solution that works, until I came across your post. :)

I just wanted to reply to everyone else here that your method works. I didn't see an issue with the Bluetooth as you had stated there were 2 instances.

Anyway, take care and thank you for this. I really appreciate.
