#196502 — failed to load iwlwifi-7265D-26.ucode but wifi works

[Multipart message — attachments visible in raw view] — view raw

Hi,

I installed Debian 9 with Debian-live-9.4.0-amd64-lxde+nonfree.iso.

But during startup I see messages that the system can not find the 
driver for the wifi card. (dmesg bellow)

But despite that I am getting access to the wifi network.

My question is whether I should leave it as is or should install the 
package firmware-iwlwifi.

But if I install this package could it generate conflict with the driver 
that is already working?

Thanks,

Markos

No, that's not what dmesg says.

Means that iwlwifi (a 'driver' for our Windows friends) kernel module
was loaded.

Means that iwlwifi tries to find a firmware for the card in the
filesystem and fails with ENOENT return code.

iwlwifi module is 'dumb'. It tries to find all the revisions of firmware that can be
possibly loaded to your particular Intel wireless card, and 'rightfully' complains
if it does not find what it 'needs'.

> But despite that I am getting access to the wifi network.

Of course you do.  iwlwifi complains that it does not find firmware with
revisions 26 through 23. Next it loads revision 22.

It says to me that iwlwifi *did* load something. Why contaminate your
Debian installation with yet another non-free firmware if the card works
with current one?

What's a legitimate question, but much better question would be - how
exactly a file named iwlwifi-7265D-22.ucode ended up being in your
filesystem?

See above. firmware-iwlwifi is already installed.

Thanks. I need to pay more attention to these little details in the future.
