Wifi is disabled in ubuntu

[jesper4]

Hi,

I have bought a new laptop with free OS and installed Ubuntu on it. Now, wifi is not working and not even showing up in the options. I have tried to update the driver as suggested on Ubuntu forums (ethernet is Realtek 8168, while it by default get the 8169 driver), so now it is correctly showing 8168 driver, but it did not help. I tried both ubuntu 16.04 and 14.04. The problem is, when I run rfkill list all in terminal, it is only showing the bluetooth thing, not even menioning wifi. I mean, wlan is not just sof or hard blocked, it does not even exist there! 

In the bios built-in options, wireless is enabled (double-checked). Internet connection via usb-connected smartphone which gets the wifi signal works fine. The small LED on the F11 key with a wifi-like icon is orange/yellow, and pressing that button, either with Fn or without it does nothing (the light stays on).

Any ideas how to solve this? It looks like wifi is not enabled on a hardware level, but I can't figure out how to enable it. Thanks!

Wow, I went through many threads on ubuntu forums, but this one has escaped my attention. It worked like a charm, thank you very much! Just for the record, worked on ubuntu 16.04, kernel 4.10.
