I'm new to Linux and I have just installed Ubuntu 18.04 having also Windows 10 as the second system and my notebook is ThinkPad T440s. When I'm on Ubuntu, I can't access Wi-Fi because it shows that there is no Wi-Fi adapter. I did some research and I think that I don't have drivers or something but I can't download anything in terminal because I was using only Wi-Fi, I'm not having wire cable with Internet. I checked what is the name of my network controller in terminal and it's Intel Corporation Wireless 7260.
Output of lshw -C network:

So after installing all packets from Ubuntu I wrote this command and all drivers got downloaded
sudo modprobe iwlwifi && dmesg | grep iwl
