Lenovo 82UF0000US

[thomaspatrickwilson]

All,

I have a Lenovo Yoga 7i.

The only problem I am having, is determining what drivers to use for the built-in wifi card.

I cannot find any information anywhere as to what wifi card is in the notebook. I suppose I will disassemble it to get a look at the system board, with the hopes of determining what chipset is used for the wifi.

If anyone has any advice, I am all ears. Thank you for your time.

Looks like its an Intel or Realtek;

Given it says it supports the latest WiFi 6 standards, I expect its actually the Intel chipset

Run a 'Live' Linux system from a USB stick, and you can ask the OS whats in it;

Fred,

It is indeed an Intel Alter Lake-P WiFi6 NIC. Please see below:

Now knowing this, and after manually copying the firmware to the Intel Firmware folder (/lib/firmware/intel), it is still not seeing the internal WiFi card. I have access to another USB WiFi5 dongle, but the goal here is to get everything that's internal to the system to work at rated capacity. Am I fighting an uphill battle that I will never win?

Thank you for your time.

[thomaspatrickwilson]

Per LSPCI, it is, as you suggested, indeed a Intel Corporation Alder Lake-P PCH CNVi WiFi (rev 01)

What do you think I should do next? I'd really like to get this internal WiFi card functioning.

[Fred Sheehan]

That WiFi chipset is already supported in the latest Linux kernels, you need to have the firmware loaded for it to work;

https://packages.debian.org/sid/firmware-iwlwifi


Unpack the firmware into;

/lib/firmware/

Firmware is also available directly from Intel;
