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


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:

And the kernel version I am using is:

uname -r 

This is the output of nmcli device show:

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.

None yet.

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

From Proposed Common Issues to Ask Fedora

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.

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 …

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

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

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
Decompressing…           [***************************************]
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. :frowning:
