Firmware issues with iwlwifi and Intel Corporation Wireless-AC 9560

powerboat9 · 12-26-2019, 08:52 AM

The wifi on my desktop computer (a Dell G3 with arch linux installed) isn't working. It looks like a firmware issue, and I've tried downgrading the linux-firmware package and modifying some of the module options for iwlwifi (led_mode and lar_disable).

Hi, welcome to LQ, powerboat9.

Wow, HOSTNAME_REDACTED on your private box? 1st time I've seen that.
Only 2 lines of that output look important to me

Code:

[  941.080638] iwlwifi 0000:00:14.3: Conflict between TLV & NVM regarding enabling LAR (TLV = enabled NVM =disabled)
[  941.280725] iwlwifi 0000:00:14.3: Microcode SW error detected. Restarting 0x0.

You're on a hardened kernel-5.4.6, right? The wifi looks recent enough. Line 1 shows (guessing) a conflict between what the kernel will allow and what the wifi microcode wants to do. You'll hardly have gotten a hardened system together without learning some stuff. Obvious meanings for NVM are Non Volatile Memory, or Node version Manager. TLV has too many meanings for me to guess, but there's a tlv.h header in the kernel, so grok that. TLV is in the kernel. LAR is location related.

/Wild Guess at the issue:
The wifi wants to broadcast your location, but the hardened kernel isn't having that. The NVM in this case would be the read-only firmware.

If I'm correct, you're going to have to let location out if you want wifi. I remember my own long struggles with hardened stuff. On your personal box, they're going to be able to guess location from your isp, anyhow.
