Just installed Ubuntu on my laptop ([Lenovo y700 14ISK](http://shop.lenovo.com/us/en/laptops/ideapad/y700-series/y700-14-inch/)). 

I am unable to get my WIFI working. Going through multiple forum posts, I figured out that i need to find the WIFI chipset type using commands like `lspci -v`, and install the controller drivers accordingly.

However, I am confused with response received for `lspci -v` as it seems to be returning both network as well as ethernet controller. But, There is no identifier that clearly states wireless chipset. Any help with figuring out right chipset and getting WIFI driver installed is highly appreciated.

The following is response from `lspci -v`:
