Here's from the log on an older (working) kernel: $ dmesg | grep iwlwifi [ 7.672955] iwlwifi 0000:04:00.0: enabling device (0000 -> 0002) [ 7.705000] iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-8000C-36.ucode failed with error -2 [ 7.705208] iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-8000C-35.ucode failed with error -2 [ 7.705391] iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-8000C-34.ucode failed with error -2 [ 7.705850] iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-8000C-33.ucode failed with error -2 [ 7.706118] iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-8000C-32.ucode failed with error -2 [ 7.706463] iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-8000C-31.ucode failed with error -2 [ 7.706789] iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-8000C-30.ucode failed with error -2 [ 7.707182] iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-8000C-29.ucode failed with error -2 [ 7.707746] iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-8000C-28.ucode failed with error -2 [ 7.714899] iwlwifi 0000:04:00.0: loaded firmware version 27.455470.0 op_mode iwlmvm [ 8.400655] iwlwifi 0000:04:00.0: Detected Intel(R) Dual Band Wireless AC 8260, REV=0x208 [ 8.475161] iwlwifi 0000:04:00.0: base HW address: [...] [ 8.568333] iwlwifi 0000:04:00.0 wlp4s0: renamed from wlan0 I'll try to upgrade the FW in the mean time, thanks! >  > https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git/ >  > https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git > > -- > Cheers, > Luca. >
