iwlwifi brocken for Intel Corporation Wireless 7260 (rev bb) because of missing iwlwifi-7260-17.ucode

[domde]

A few days ago, my wireless stopped working. Dmesg showed the following:

[ 4.499602] iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-7260-17.ucode failed with error -2
[ 4.507101] iwlwifi 0000:02:00.0: loaded firmware version 16.242414.0 op_mode iwlmvm

[ 9.585041] iwlwifi 0000:02:00.0: L1 Enabled - LTR Enabled

Toggling the kill-switch did not enable the wifi.

It seems that the problem is fixed by installing the latest version of the firmware by downloading
https://raw.githubusercontent.com/OpenELEC/iwlwifi-firmware/master/firmware/iwlwifi-7260-17.ucode

and placing it within /lib/firmware

modprobe -r iwlwifi

and

modprobe iwlwifi

resulted in the following dmesg-logs:
