Firmware for wireless failes to load with kernel 4.3
 
Upgrading the kernel from version 3.14 to 4.3 left me without wireless, since it fails to load the necessary firmware:
Code:

# dmesg
...
Direct firmware load for iwlwifi-7260-16.ucode failed with error -2
iwlwifi 0000:04:00.0: Falling back to user helper
...



The kernel module gets loaded though:

Code:

lsmod
...
iwlwifi                93508  1 iwlmvm
...

Here is the hardware built into my laptop

Code:

lspci -nnk

04:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b2] (rev bb)
        Subsystem: Intel Corporation Dual Band Wireless-N 7260 [8086:c260]
        Kernel driver in use: iwlwifi
        Kernel modules: iwlwifi

Thanks for your help on how I can fix this issue

Hi....

I'm not sure if this is your issue but does the information here help? In case you need to download new firmware, you can find that here. :)

Well, this might be the reason. But quite frankly I don't see why I should tinker with my system and possibly break it even more. Up to kernel version 3.16 wireless firmware gets loaded without any issue. See this thread here, all of a sudden I get so many problems not only with newer kernel versions Ear phone jack not working anymore

Hi...

I don't blame you but I don't think you're looking at an easy fix with either issue. I could be wrong but it might be easier to back up your files and reinstall the OS (with the old kernel) from scratch. If you can find a copy with the new kernel, you can try that as well. ;)

Hi ardvark71,

you are right of course there doesn't seem to be an easy fix available. I found out that having a LAN cable plugged in (as is the case at home) contributes to the sound problems mentioned in the other thread. At the university's library where only wifi is available there are no sound issues, but well, it would be a good thing to have wifi there :-P

I just don't know what to make of it. I am really not looking forward to reinstalling my OS. Even with a complete backup of my HOME-partition including all configuration files, there still is the task of backing up all systemd settings and lvm stuff for my SSD. To me it's strange that all kernel versions after 3.14 cause so many problems. It tried other versions before and had issues on the application level like file handling. That's me complaining.

The reason why I am looking for a new kernel is that the newer ones have a better power management according to my past experiences with Linux on laptops. Otherwise for me as a simple DAU I cannot feel much of a difference.

Anyway thanks for you help, I appreciate it. The tutorial for manually installing the wifi firmware seems too complicated to me when one has to tweak udev settings, and probably systemd settings as well.

Hi...

You're welcome, I hope you can get it squared away. :)

For now, things seem to have got back to normal. Using kernel version 3.14 lets me use wireless and headphones again.

Maybe I will find the time to look into the firmware issue.

Thanks for your help, now I know where to look
