Fedora 39: Lenovo ThinkPad P16s Gen 2 - Intel Raptor Lake PCH CNVi WiFi frequently disconnecting

[bgarcial (Bernardo Garcia)]

Problem

I installed Fedora 39 workstation two months ago, and suddenly recently I am running into the problem of my wireless card disconnecting frequently. It is happening in various locations (at home, at my work, etc.)

When i do lspci -nnk I got this as a reference of my wireless card:

Cause

This is a similar issue, https://github.com/lwfinger/rtw89/issues/240 but for realtek wireless cards where they propose a workaround regarding the rtw89 driver being built on the kernel

It seems that the driver for those cards (INtel and realtek) are not behaving well in Lenovo and HP laptps, but the cause itself is not yet known.

Related Issues

Fedora 39: HP Laptop, Realtek RTL8732DE Wireless WiFi issues

There are several threads here about issues with that realtek card, and yes some just recently with the newer 6.X.X kernel. My suggestion: Replace the realtek card with an intel card which seems much more reliable. Most laptops have the wifi card that is easily replaced just by opening the case.

WiFi failure requiring reboot - Fedora 39

Note that the processor responds to chip temp much faster than even lm_sensors can report it. Monitoring lags significantly behind actual temps. I had a cpu with water cooling with a failed pump. Monitoring with lm_sensors only showed about 50C but the processor was shutting down the system with temps at about 90C internally. The rapid temp rise could not be reported before the shutdown.

Wifi wireless problem

Hi, Thanks for your help, I have read the thread you send me and my problem is not solved. I don’t think the problem is coming from my wifi card because it was working just before the update. Downgrade the version of iwl didn’t work. And I can’t manage to find the apropriete driver from the intel website for my device. Also I don’t think I’m facing exactlly the same problem than on the thread, for me the output of dmesg | grep iwlwifi is [ 8.978427] iwlwifi 0000:00:14.3: enabling device (0…

None yet.

I will appreciate if someone has some input or ideas about how to tackle this.

LHDB user comments for your PCI 8086:51f0:8086:0090 mention an old bugzilla report and a manual firmware update. As always, make sure you are fully current with Fedora and vendor updates so you aren’t fighting a problem that has been fixed. My many years of linux experience have taught me the importance of having a USB wifi device while waiting for issues liek this to be fixed.

[bgarcial (Bernardo Garcia)]

Thanks @gnwiii for your response.

I just discovered that this is actually happening to both my wired Ethernet and USB wired Ethernet as well. As consequence, I cannot suspend my laptop because If I do, I loss connection over all my network devices (wireless and both wired).

I’ve downloaded the firmware from this section and proceed with the copy (cp iwlwifi-*.{ucode,pnvm} /lib/firmware/) and loaded the driver again (sudo modprobe iwlwifi) but it did not work my wireless card still get disconnected when I suspend my machine.
I also make sure my machine was fully updated in drivers and hardware data regarding Fedora OS and vendor pci before doing this.

Talking with Lenovo Support, they say for this laptop (ThinkPad P16s Gen 2) the Linux OS supported or what they called CERTIFIED are Ubuntu 22.04 and RHEL 9.2 as this link states: (Check under Notebooks and Laptops dropdown)

But this is not an impediment in order the firmware can be updated with copying the files as the intel documentation says right? Is a bit weird …

@bgarcial

But this is not an impediment in order the firmware can be updated with copying the files as the intel documentation says right?

Since both ethernet and wifi interfaces work but fail to wake-from-sleep, the failure may be in system firmware settings. Enterprise grade laptops are often designed so HQ can install updates remotely. Before I retired, we were told to leave our enterprise issue laptops (running Windows) turned on after hours. From time to time, updates would appear with a notice that the system needed to be rebooted. This is done using “Wake on LAN” or “Wake on WLAN” packets with the network devices in a low-power mode.

yes, and it seems according to this list,my laptop reference is not yet for Fedora 39

List of computers that ship, support, or should be friendly with Fedora Linux

As part of our Strategy 2028 initiative to get Fedora shipping on more computers out of the box, the Marketing Team wants to improve our support of hardware vendors who choose to ship or support Fedora for their products. One of pain points that came from that was ambiguity over how to actually buy the computers that ship Fedora. Where do you configure that? What’s the link that you’re supposed to use? And why is it so hidden away? As the first step in solving this problem, we put together a t…

From Lenovo side, they say for my laptop the only ones what they called “CERTIFIED” are Ubuntu 22.04 and RHEL 9.2 according to this link

Lenovo ThinkPad P16s Gen 2 (i7-1370P RTX A500) certified with Ubuntu | Ubuntu

and I found this firmware update, LVFS: ThinkPad T14 Gen 4 / P14s Gen 4 / T16 Gen 2 / P16s Gen 2 but that is older than I actually have:

fwupdmgr install 2f28abef4bb7851704ffccc8f685c84a84d79a401a3d9ea5011ff59b2875f66b-N3QET39W.cab

Specified firmware is older than installed '0.1.39 < 0.1.43'

I s a bit frustrating, I really likes Fedora, but I cannot pretend unstall Feodra 37 expecting my system never will upgrade itself at some point.

[gerar (Gerardo R)]

Sorry to necropost, but did you ever find a solution for this? I have a similar wireless card (Intel Corporation Raptor Lake-S PCH CNVi WiFi [8086:7a70]) that came with my TUF GAMING Z790-PLUS WIFI MoBo and I’m having the same issue with Fedora 41.

[bgarcial (Bernardo Garcia)]

Hi @gerar, no worries at all!
After several backs and forth with the vendor support, they changed the motherbord of the laptop, but at this point I am not even sure if that did the trick, since the problem persisted for several days after that, then it turns out all of sudden the updates for the firmware started to appear on the software center. I am even not sure if Fedora itself released them or the vendor did something about it.

The thing is that after all this, I ended up with a new motherboard.

I want to share with you some links that I explored along the way, they maybe useful for you.

However it seems this problem is apparently particular for every machine or so.
