Issues & Assistance

After updating linux-firmware from 20260309 to 20260519, my Intel Wi-Fi 6 AX201 stopped working.
Error: iwlwifi-so-a0-hr4-b0-89.ucode not found Hardware: Intel Wi-Fi 6 AX201 (PCI 51f1) Kernel: 6.19.10-cachyos / 7.0.11-cachyos
The file iwlwifi-so-a0-hr4-b0-89.ucode is not present in any version of linux-firmware package available in the repos.
Reference: [SOLVED]No suitable firmware found for iwlwifi - kernel 6.16.5-arch1-1 / Kernel & Hardware / Arch Linux Forums

Have you tried turning the system off and removing the power cable as mentioned in that thread?

You shouldn’t be having 6.19.10-cachyos installed at the same time as 7.0.11-cachyos.

There seems to be some sort of “inconsistency” in your system.

6.19.10-cachyos is already superseded.
