Not always a success story. Since this is a work in progress kind of thing (I currently struggle with it), I will be very brief. I hit some issues (instability) on a brand new laptop using Debian derivate distro (both Ubuntu and Mint). I had a bit of comfort seeing that I’m not alone. The exact error and similar symptoms are to be found here. It seems to be either firmware or adapter settings related. I noticed that on Intel’s page there is a newer version of iwlwifi-3160-ucode-126.96.36.199.tgz versus iwlwifi-3160-ucode-16.242414.0.tgz on Linux Kernel’s page. I will follow this lead for the moment. If I feel that I need to spend too much time with it, I’m going to take more radical measures (install something else).
Update (5 min later):
It seems that version I downloaded from Intel’s page loads without problem.
