Wifi is not working on fresh install

kjmoraes31 · 11 December 2021 11:53

This is about a problem with the wifi connection on a fresh install of Manjaro KDE Plasma with kernel 5.13. On a fresh install of Manjaro KDE on this Thinkpad T14 Gen 2, there was no wifi connection option. My

inxi -N output is

Network:   Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet driver: r8169
           Device-2: Realtek driver: N/A
           Device-3: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet driver: r8169

lspci -vv | egrep "r8" output is

Finally, sudo dmesg | egrep "r8" gives

The ISO file I flashed came with a 5.13 kernel but I upgraded it to a 5.14 and then 5.15. I am currently using USB tethering to get Internet access on this device.

So far I have tried :

Blacklisting the r8169 driver and using r8168 and doing mkinitcpio -p linux515 This didn’t work.
Booting into Fedora on a live disk. Even this couldn’t pick up the driver
Changing to an LTS kernel (5.10) and rebooting.

The machine initially had Windows on it and I managed to use wifi so I am quite sure it is not some hardware issue.

Could someone please point out a solution ? Thanks in advance.

Additionally, should I follow the instructions given here
https://forum.manjaro.org/t/no-available-wi-fi-network-detected/18272/60?u=kjmoraes31
This thread was for the rtl8821ce driver, so if I could, what changes would I need to make for the r8168 driver ?

Mirdarthos · 11 December 2021 13:07

First: I have no, nada, 0 experience with anything sound-related, but I have heard these 2 sound-servers can’t work together.

Secondly, regarding your question, dkms drivers for the r8168 driver is in the AUR:

$ pamac search r8168
[...]
r8168-dkms                                                                                                                                                                                              8.049.02-1    AUR
A kernel module for Realtek 8168 network cards (DKMS version)
[...]

So, it can be installed with:

pamac build r8168-dkms

In theory it should work. If it foes, feel free to heap on the praise.

megavolt · 11 December 2021 13:45

That must be the wifi:

In general it have to be done like that:

Your device is an Realtek Semiconductor RTL8852AE 802.11ax PCIe Wireless Network Adapter

At the end it is:

pamac install linux515-headers

pamac build rtw89-dkms-git

You need to install the headers for each kernel you want to run.

kjmoraes31 · 12 December 2021 07:26

Thanks a lot. This worked. Additionally I think the wifi speed is a bit slow (in the Kbps). Should I try something else to maybe get faster speeds ?

kjmoraes31 · 12 December 2021 07:27

Thank you for the reply. I fixed the wifi issue but what should I do about the sound problem - do you know of any other forum posts / wiki posts that I could refer to ?

megavolt · 12 December 2021 07:35

Maybe disabling aspm could make a difference… have look at the Section option configuration

modinfo rtw89pci

Mirdarthos · 12 December 2021 07:40

I suspect you’ll have to stop and mask either the PipeWire or the PullseAudio services, but I am obviously not sure.

I THINK:

To use pulseaudio, you need to stop and mask Pipewire:

sudo systemctl disable --now --global pipewire

To use Pipewire, you need to disable and stop pulseaudio:

sudo systemctl disable --now pulseaudio.socket &&  sudo systemctl disable --now pulseaudio.service

But that’s according to my (very) limited knowledge so it might very well be wrong. In fact, I’d be surprised if it isn’t.
