Realtek Network Adaptor

Support Network
1

Something messed up with my laptop and it lost functionality to access the internet, to which I connected my old adaptor in and it wasn’t working.My friend tried to fix the problem but couldn’t, and now there’s 2 wifi networks. (wlan0 and wlp2s0). When wlp2s0 disappeared for a moment I was able to connect to wlan0 for about an hour but then it disconnected again and now when I try to connect wlan0 it deactivates, tries to connect to wlp2s0, and fails

Apologies in advance, this is my first time posting in a forum and I’m still getting used to Linux

Update, now the normal network appears instead of the two but I still can’t connect lol

What do I do now?

I suppose those are the 2 … any idea which you prefer? They are both a bit problematic.

If we want to test out the rtw_8822be first you could try this:

  • Edit /etc/default/grub line GRUB_CMDLINE_LINUX to contain the following:
    pcie_aspm.policy=performace so it looks like (assuming no others are there):
    GRUB_CMDLINE_LINUX="pcie_aspm.policy=performace"

  • Then run
    sudo update-grub

And reboot.
You may want to remove the other card if that is simple enough.
Otherwise we could disable it with modprobe or similar.

6

I do not know what you mean by which I prefer, I only have 1 adapter plugged in, and the built-in one for the laptop which doesn’t work

I’ll give that a shot though

7

Yeah all the better to start with trying to work out the internal since we can remove the USB.

When finished, assuming its not working still, please return again:

It’s not working still, so-

sudo modprobe rtw88_8822be && sudo ip link set enp1s0 up

anything there?

(PS - even with the extra usb the output of 6 here is a bit odd)

modprobe: FATAL: Module rtw_8822be not found in directory /lib/modules/5.15.2-2-MANJARO

(PS, I have no idea other than the fact it’s tethered to my phone)

13

Ah that could make sense.

Could you also try an earlier LTS kernel?
Like 5.10 ?

14

I can, it may take awhile though as my tethered connection is a few bits per second

15

I have 5.12.19-1 if that works

16

Sadly its EOL … so it may be worth a try since its already installed … but I think 5.10 is the way to go, especially with the modules and all.

17

Is 5.10.79-1 fine? Idk if there’s a difference between this and what you mention, but I do have this one

18

Oh already installed? Then yes please just drop to that one from a reboot.
(hit shift to pull up grub and select kernel)
But this talk makes me wonder … is the system up to date? Or avoided because of this situation?

19

I haven’t used this laptop in 3 months, I haven’t fully updated everything due to the internet problem yeah

I’ll boot into the older version :slight_smile:

20

When you do … can we get an output of the full inxi again (make sure the boot param is applied, etc)
