Rocky Linux 9 does not support Intel I219-LM

I found this post which coincidentally has the same network card, but a different Device ID.

0000:00:14.3 Network controller [0280]: Intel Corporation Alder Lake-S PCH CNVi WiFi [8086:7af0] (rev 11)
0000:00:1f.6 Ethernet controller [0200]: Intel Corporation Ethernet Connection (17) I219-LM [8086:1a1c] (rev 11)

I double checked ELRepo | Device IDs to make sure it wasn’t a fluke, but when searching for both of these Device IDs, I get a “Not Found” search result.

This is actually a new Dell Precision 3260. Interestingly I get minimal functionality (1-3% download speed, 50% upload speed), for Ethernet, and 8-10% download speed, 75% upload speed on Wifi.
Thank you

Given how new your hardware is, you’ll be better off running a newer kernel. Alder Lake in particular is poorly suited to the stock kernel (5.14) because Intel Thread Director features only landed in 5.18.

ELRepo is in the testing stages of releasing their mainline kernel, I’d suggest trying that https://lists.elrepo.org/pipermail/elrepo/2022-September/006208.html

I’m running an Alder Lake system with 6.0.0-rc6 (don’t do this, do 5.19.10), a guide to installing custom kernels is available at Building and Installing Custom Linux Kernels - Documentation

Thank you for the information. I will look into this in the morning.

Strictly, that is not “does not support”. That is “has bad driver”. “Almost works” is different from “No, I’m not touching that!”.

Both of them appear to have driver in EL9:

$ modprobe -c | grep 8086.*7AF0
alias pci:v00008086d00007AF0sv*sd*bc*sc*i* iwlwifi
$ modprobe -c | grep 8086.*1A1C
alias pci:v00008086d00001A1Csv*sd*bc*sc*i* e1000e

Actually, going to RH bugzilla and searching with “e1000e” finds this: 2094200 – e1000e painfully slow on I219-V NIC
That was on different Intel NIC model, so the fix that should appear with RL 9.1 might not apply to 8086:1a1c. Anyway, a workaround is mentioned there. Perhaps it helps?

There are ‘iwl*-firmvare’ packages in repos. I presume that they match some Wifi chips. Personally, I like Wifi if I can plug a fiber … :woozy_face:

Since Red Hat has decided to support these devices in RHEL 9, bug reports should go to them. Here, on Rocky Fora, peer support can at most suggest workarounds.

There are neither kmod-e1000e nor kmod-iwlwifi packages in ELRepo for EL9, so ELRepo “does not support” EL9 for these devices. They might add support, if requested.
