I've recently installed Ubuntu 16.04 on my device (alongside Windows 10) and I cannot get it to connect to the internet via WiFi. I have tried using the cable for an Ethernet connection but the Wifi option seem to be missing. Now of course I did my research and all the solutions I have found proposed going to the "Additional Drivers" and change the settings there; problem is, I did go there and there are no drivers available for me to select from. Is there any way for me to fix this? How? Thanks in advance.

~~Edit after running sudo lshw -class network the output was:

Also, after lspci -knn | grep Net -A3:
