I have a ThinkPad T14, its supposed to be Linux-certified but i am unable to even detect the WiFi card using both Manjaro and Ubuntu (for which it’s certified).

The output to lspci is:

How should I proceed?

Hi @trashvap ,

Welcome to the forum!

The output you provided above only shows the Ethernet pci card.
In order to see the wifi card you have to post the output of the following terminal command:
inxi -Fazy
Please, also read how to provide good information in the following post before you answer:

Hope this help, regards.

All i can see is the Ethernet card, the WiFi works under Windows so I know the card works.

  1. Please install a spell-checker in your browser.
  2. Please leave a blank line before indenting
  3. Please press the orange pencil above your posts to see what I changed.
  4. Realtek is know to have issues with its Linux drivers, so try both latest LTS kernels (5.10 and 5.4) and see if the problem goes away all by itself.

I am doing my best to conform to the forum format, thank you. As for changing the kernel, it had no effect on this issue.

Hmm. Thought they only use Intel AX200 chips for WiFi with this model.
Seems to be some Realtek adapter though.

Try this driver:
