So my computer runs on Ubuntu 18.04 and since I installed it the WiFi drops randomly and I can't relaunch it because it doesn't do anything with the GUI and when I type "service network-manager restart" it loops and displays : "iwlwifi 0000:02:00.0: Failed to run INIT ucode: -5" and "Failed to start RT ucode: -5".
I already tried to install the drivers from Intel's website for my network card which is an Intel 3160 and it didn't change anything.
Thank you

Here is the dmesg output after wifi drops.
