Comment # 13 on bug 1021082 from Takashi Iwai

[    3.805567] iwlwifi 0000:02:00.0: Direct firmware load for
iwlwifi-7265D-26.ucode failed with error -2
[    3.805579] iwlwifi 0000:02:00.0: U iwl_request_firmware attempting to load
firmware 'iwlwifi-7265D-25.ucode'
....
[    3.805782] iwlwifi 0000:02:00.0: no suitable firmware found!

So it implies that /lib/firmware/iwlwifi-7265D-*.ucode is missing.  TW
kernel-firmware package contains iwlwifi-7265D-22.ucode file.
