Mostly for backwards-compatibility, the driver is able to work with a range of firmware versions. It only uses one of them at a time (i.e. the highest supported version it finds). The driver in v4.14 support version 34 and below. So it starts looking for that one and, if not found, falls back to the next lower version (i.e. 33) and so on, until it finds one. > [ 10.630285] iwlwifi 0000:04:00.0: firmware: failed to load > iwlwifi-8265-34.ucode (-2) > [ 10.630331] iwlwifi 0000:04:00.0: Direct firmware load for > iwlwifi-8265-34.ucode failed with error -2 > [ 10.630454] iwlwifi 0000:04:00.0: firmware: failed to load > iwlwifi-8265-33.ucode (-2) > [ 10.630479] iwlwifi 0000:04:00.0: Direct firmware load for > iwlwifi-8265-33.ucode failed with error -2 > [ 10.630486] iwlwifi 0000:04:00.0: firmware: failed to load > iwlwifi-8265-32.ucode (-2) > [ 10.630510] iwlwifi 0000:04:00.0: Direct firmware load for > iwlwifi-8265-32.ucode failed with error -2 > [ 10.636423] iwlwifi 0000:04:00.0: firmware: direct-loading > firmware > iwlwifi-8265-31.ucode > [ 10.637463] iwlwifi 0000:04:00.0: loaded firmware version > 31.532993.0 op_mode iwlmvm This is an unfortunate side-effect of the way firmwares are loaded. There is currently no way to prevent these error messages by making some files optional... But you can ignore them. Or, even better, upgrade your firmware to the latest version the driver supports. :) -- Cheers, Luca.
