Tried an Intel 8260 module [8086:24F3] subsystem [8086:0010] on a Intel Comet Lake platform with kernel 5.6-oem, 5.8, 5.11. All works just fine with linux-firmware version 1.187.17.
While its firmware, iwlwifi-8000C-36.ucode, has never ever been updated since linux-firmware/focal was released, we'll need complete information of your system for further inspection. $ md5sum iwlwifi-8000C-* fd0ac79f34b10ce98d58100b509be73f iwlwifi-8000C-13.ucode 2d2b06c5644c9d718e7c0495aafa215b iwlwifi-8000C-16.ucode d7c59c75d442b6c0a10cb7505ca2dd6a iwlwifi-8000C-21.ucode 2d192842e3d76c574ab1a4513d06000a iwlwifi-8000C-22.ucode dbed38f155cada773ebdfb78ed4f5ebc iwlwifi-8000C-27.ucode 6b201b78799a78d154bfdd67e12792f0 iwlwifi-8000C-31.ucode 6bdfcdc1b5564504f0a8ff2de21b172a iwlwifi-8000C-34.ucode e4d63f8eaaf9d03d0c1dcfb3af435e48 iwlwifi-8000C-36.ucode -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1943684 Title: upgrading from 1.187.15 -> 1.187.16 breaks iwlwifi for intel 8260 Status in linux-firmware package in Ubuntu: Incomplete Bug description: After a reboot my wifi suddenly didn't work anymore, dmesg showed: [ 8.711330] iwlwifi 0000:04:00.0: SecBoot CPU1 Status: 0x3040001, CPU2 Status: 0x0 [ 8.711336] iwlwifi 0000:04:00.0: Collecting data: trigger 15 fired.

Downgrading to 1.187 (for unknown reason I couldn't find the binary of the old version 1.187.15 on my notebook nor on the internet anymore), and reloading the module as described in https://openterprise.it/2019/04/linux-reload-intel-wireless-card- kernel-module/ brought the wifi back.
