  1. Please read this:
    How to provide good information
    and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies…

  2. An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information… (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
    Also, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text.


P.S. If you enter a bit more details in your profile, we can also see which Desktop Environment you’re using, which CPU/GPU or Kernel, … you have without typing it every time

Thanks man I’ll input that and send it you

Please see this post:


If it requires linux kernel headers, then install them if they are not installed.

How doni install the headers for it

Install the linux kernel headers that apply to your kernel e.g. if using kernel 5.10:

Okay I’ll try that and get back to you

To install the linux headers you need to know which kernel you’re running. Run,

uname -r

in a terminal to find out which kernel you’re running at the moment. For example, I’m running 5.10, and my output looks like:

$ uname -r

To install the headers for linux kernel 5.10, you’d have to find it in the repositories first:

$ pamac search linux510
linux510-headers 5.10.23-1        core
Header files and scripts for building modules for Linux510 kernel

Then, to install the headers, you install them with 1pamac install`:

$ pamac install linux510-headers

Fo9llowed by a reboot.

That is the best way to do it, in my opinion.

Hope this helps!

Thanks I did that installed the 510 headers and rebooted but it just didn’t work

I’m assuming you did it because you’re running kernel 5.10. Did you follow the instructions in the link @jrichard326 gave you after you installed the headers?

If so, and it’s still not working, please provide the information @Fabby asked for earlier.

Yess I did do it but doesn’t wanna work

Won’t let me send picture

Don’t send a picture. See

Ps I do appreciate the help


I’m extremely sorry to say this, and I’ll probably get in trouble for it, but for anyone to help, more information is necessary. And I did give you a link for a guide on how to provide it. a Very good guide, if you ask me.

Without that info, and possibly more, you won’t get any help, because nobody on here are mind readers, even if what they can do sometimes looks like magic.

So, I’ll give you the link again: How to provide good information

Oksu whats that

Please read this:

and this again:

as you’ve only posted partial information.


I’ve also just come across this:

$ pamac search 8168
r8168-dkms                                                                                                                                                                                              8.048.03-1    AUR
A kernel module for Realtek 8168 network cards (DKMS version)
linux510-r8168                                                                                                                                                                                          8.048.03-38   extra

So, in theory, it should work if you install r8168-dkms.

pamac build r8168-dkms

But at this point it’s only guessing and it’s not a certainty.


That’s not the USB WiFi I have the onboard drivers installed
