Intel AC 8260 firmware load failed

[Kuizatzhaderach]

Hi, have an Alienware 17R3

I recently replace a Killer wifi card with and intel AC8260. Now the wifi works OOB and well.

However DMESG reports that the firmware failed to load, as below.

I have kernel
Linux AlienIX 4.4.0-98-generic #121~14.04.1-Ubuntu SMP Wed Oct 11 11:54:55 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

I downloaded the latest firmware from Intel for the card however its
/lib/firmware/iwlwifi-8000C-13.ucode

Is this really a problem ? obviously the system is looking for 14-19

dmesg | grep failed

That wifi won't work at all without firmware, the results from terminal for

Code: Select all

lshw -c net

Should show that version 13 of the firmware did load or you could

Code: Select all

dmesg | grep iwl

And possibly see that the firmware loaded

Thanks very much for the reply. The wifi works quite well, however as you say it looks as though it has actually loaded .13 ?

Hi Jeremy, obviously the device is recognised and is loading firmware, however I would interested to know what it has actually loaded ?

Cheers
