I couldn't modprobe rtw89-dkms

25

Can you please clarify this?

You do not need to modprobe rtw89-dkms.
As above - 8852be is merged into rtw89. So you would modprobe 8852 except that you would only do so if you installed 8852 as a module.

That reply was for @zabadabadoo regarding problem with Wi-Fi on Windows.

I need to issue "sudo modprobe rtw89-8852be" , right?

28

Oh, I see thanks.

You might try sudo modprobe rtw89pci but realistically, you should not need to modprobe at all in these steps.
Also please note 337harveys post above.

Finally i found someone who has the same problem as mine.
This thread exactly describes what i'm trying to say: No available wifi networks shortly after booting up - #66 by ricklinux - Newbie - EndeavourOS
Yes, wifi comes but goes off eventually after few seconds or minutes with rtw89-dkms.
Looks like they merged the driver but it doesn't work as expected. Can you please tell me where can I raise the issue?

Few logs:

You sadly may need to consider getting a Wifi USB adapter that is Linux Compatible.

(Side note: This thread is marked as Solved - but the recent posts imply it is not yet solved.)

Hi @Aravisian
Sorry for spamming the thread after I marked a solution.
Of course it solved the problem but it is a work around and there is some work involved every time there is a kernel update.
Sometimes I panic when WiFi cutoff when I just do sudo apt upgrade and then I realize that I need to recompile the drivers and reinstall (if that upgrade involves a kernel upgrade).
Sure, the problem is solved but PARTIALLY.
I'm sure this thread will be useful for the people who buys a laptop with this hardware.

Let this be the last reply in this thread.

Not at all. It was me that misunderstood. I had thought that your Wifi was cutting out after a few minutes of use.

Yes - having to reinstall the Wifi Drivers after each kernel upgrade can be annoying. But, there is a workaround for that, too. You can lock the kernel in so that you may upgrade fearlessly.
