No WIFI Adapter Found and Bluetooth acting weird RTL8822BE

Hi! i have a low spec laptop that used to run WIN11 and always worked fine.
Now i wanted to try linux (fedora35) but after installation there was no WIFI so i had to make the connection via bluetooth tethering for all the updating stuff.
To make it short:

*Bluetooth is always on when laptops boot (even if turned off before shut down)
*When i turn bluetooth off, then airplane mode turns it self on and if i turn airplane mode off, again BT is back on (facepalm)
*WIFI adapter is always disabled, no menu, no nothing

I have tried many online possible solutions and sometimes after that, WIFI adapter shows up (has menu, i can see network near me and even connect to mine) but as soon as i open youtube or anything BOOM it disconnects and is not going to show again (no networks near me, no name in the up right menu, nothing)

So after many many attempts i discovered that if i turn bluetooth off, then turn airplane mode off, then again my bluetooth off and then turn off my laptop (not reboot but complete turn off) then when i go back on, the WIFI adapter will appear and i can interact with it (looking to networks nearby, making a succesful connection to mine) but as soon as i put any load on it BOOM dissapears again.

So thats the problem after installing and reinstalling my Realtek drivers, im stuck with bluetooth tethering jejeje i have to say, im learning a lot :slight_smile:

I can see from top to bottom the first rtw_8822be entry without any driver even tho i just installed the thing :thinking:

Hi,

I would try this:

Thanks Tom.

I can confirm that I am attempting to install the modules for rtl8821CU on three distros. (Ubuntu, Manjaro & Fedora) and for each I required …

Clone the appropriate git repo.
Install dkms
Run the dkms script downloaded from git

Well, i can confirm now that drivers are indeed installed but just not loading properly.
I was able to download 25Gb worth in data last night via WIFI, it worked flawlessly :thinking: weird i know…

i did this:
turned everything off (buggy wifi that is not showing properly, BT)
Shut down laptop
Turn On laptop
My BT is ON on its own as usuall
My WIFI its off as it should
So then i turn off BT, airplane mode turns ON by itself
I shut it off
BT turns on automatically after shutting airplane thingy off but i inmediately switched off again
Now everything is off
I turn WIFI on and it worked!
Downloaded a bunch of stuff but…

After reboot, everything went caos again “No wifi network adapter found” therefore i dont have any WIFI menu, just stuck with bluetooth menus so i cannot replicate steps above anymore :wink:

Hi,

Looks like the link I provided was out of date, please try the latest drivers:

Thanks Tom.

UPDATE:

I was able to replicate my steps after i remove rtw_8822be Module and load 8821ce module and then restart.
My WIFI showed buggy (no name on it, just the antenna icon) but at least i could turn it off and replicate steps shown on first post and then reboot.
i have a working WIFI. Not a solution but it feels good :slight_smile:

Im goint to try your second link @tjdoyle and let you know if i can manage a permanent solution.
Thank you!

(proof now i have a driver :point_down:t3:)

One thing I have to do to get the WIFI working properly is to disable the USB CD ROM mode of these adapters.

my lsusb show this before disabling :slight_smile:

$ lsusb
Bus 001 Device 002: ID 0bda:1a2b Realtek Semiconductor Corp. RTL8188GU 802.11n WLAN Adapter (Driver CDROM Mode)

$ sudo usb_modeswitch -KW -v 0bda -p 1a2b

But after the mode switch the device characteristic change to :

$ lsusb
Bus 001 Device 005: ID 0bda:c820 Realtek Semiconductor Corp. 802.11ac NIC

After switching the mode the wifi is automatically detected and my network connects.

Unfortunately this is my output for lsusb… No (Driver CDROM mode) to test in my system.

But thank you for posting :metal:t3:

@wallyz
This is a different issue with your RTL8188GU adapter and the RTL8821BE adapter posted by @annamemnon .

Little update here.

:point_up_2:t3:
This only happens when my laptop is connected to the power.
When i turn it on battery only, wifi appears (glitchy but appears) so i can then reproduce this steps.

Waiting for the official Fedora36 still :slight_smile:

OK, just a bit of my $0.02.
The indication of airplane mode on is based on the fact that all wireless communications are disabled (both wifi and bluetooth) so that would be expected.

Since bluetooth was the last disabled and that is what turned on airplane mode, then turning off airplane mode would automatically re-enable bluetooth.

Your real issue is the driver for the wireless adapter. It appears that you do not have the proper driver, and the driver you do have only supports bluetooth on that adapter chipset.

Lets quit worrying about how the issue is presented and instead handle the fix. Locate and install the proper driver.

A quick google search for driver for wifi adapter 10ec:b822 (which is your chipset) shows many links and it will be up to you to see which is the best for your needs. Adding ‘fedora’ or ‘linux’ to that search changes the number of results and may or may not narrow down what is needed.

My device is an 8821CU (IEEE 802.11ac/a/b/g/n WLAN and Bluetooth combo module with on-board 2.4Ghz and 5.8Ghz Dual band antenna)

Realtek RTL8821CU chipset ( USB ID = 0BDA:C820, Initial CDROM mode = 0BDA:1A2B )

Why it shows as a 8188GU under lsusb is anyones guess.

What I’m saying is a lot of realtech devices default to CDROM mode and sometimes that needs to be addressed.
