Wifi Connection Problem for Thinkpad E570 Model

[nightxlord]

I tried everything on forum that provided how to fix the wifi connection for Linux Mint Cinnamon 18.1.
But I still do not get the wireless working at all. The only thing that are working is that I have to connect the LAN cable for it.
Please help Me!

Thanks, backport-iwlwifi works for me.
Sorry for asking stupid question but why there is no driver for wifi out of the box?

There is, for a lot of different hardware. Just not for ALL the hardware.
