Issue description

Wifi with a recent update on release-16.09 has unstable wifi. Internal wifi module starts breaking off connectivity after a while. I've not yet determined which exact update is the cause. Going back a few generations of NixOS fixes the issue. The issues happens with linux 4.4.45 and not with 4.4.39.

I cannot reproduce this problem with the same wifi chip and the same kernel version on unstable on a T440s.

@vandenoever Have you reported this upstream?

@abbradar no

I have reinstalled a fresh NixOS since I was suspecting btrfs of having corrupted some files, but that did not fix the issue. With a fresh NixOS install the issues is still there.

As a data point, similar Intel hardware has been flakey in Arch Linux for me:

I've updated our non-free linux firmware in 01cf43a a few days ago. This included a bump of the firmware for your devices (fpletz/linux-firmware@350a192) which could maybe help?

@fpletz will that land in release-16.09 or is there a way to test it while remaining on 16.09?

I've removed all iwlwifi-8000C-2[2-7].ucode firmware files to make iwlwifi-8000C-21.ucode the first option. On my P70 with Intel 8260 chipset wifi works again.

https://bugzilla.redhat.com/show_bug.cgi?id=1390453 suggests version 22 is broken.

@ookhoi Pushed a new version with those two bad version removed.

@vandenoever I've backported the firmware updates to 16.09.

I hope this fixes the issues you were experiencing. Please reopen if not.

I'm still seeing version 17.352738.0, I assume it will take a while for the fix to make it to 16.09.
