I'm relatively inexperienced with Linux. I've done a number of installations, but they were all either pretty much straight out-of-the-box JEDI installations with a UFO box or installations on Raspberry Pi.
This is my first installation on a laptop. The Toshiba C55-C-184 came with Windows 10 pre-installed. I replaced this with Ubuntu 16.04 - I need to install ROS on Ubuntu for an online robotics course - however it looks like I'm failing at the first hurdle!
I've searched the forums and I've seen that several people have had problems with other Toshiba laptops, but I can't find anything that helps. Other (earlier?) Toshiba laptops seem to have used Realtec controllers for wireless connectivity, and most of the solutions that I have seen seem to focus on that. Unfortunately, this one seems to use an Intel controller, so those solutions just don't work.
I ran lspci -knn, and got this output:
lspci -knn | grep -EA2 'Eth|Net' Network controller : Intel Corporation Wireless 3160 [8086:08b3] (rev cb) Subsystem: Intel Corporation Dual Band Wireless AC 3160 [8086:8170] Kernel driver in use: iwlwifi

The output from rfkill list all:

Any help will be appreciated. Especially if you can explain why it's not working as well as how I can fix it. I'm always happy to expand my working knowledge of Linux.
UPDATE: Given how many posts I've seen about wifi problems on Toshiba laptops, and since I really cannot find anything to explain why I'm seeing this problem, I've posted a question with Toshiba support to see whether this is a known problem with Toshiba laptops. Maybe they can suggest an answer ...
UPDATE2: Well, I got a reply from Toshiba support:
"The issues you report are most likely software errors and in this case we advise that you reinstall Windows 10."
Not exactly helpful, are they?
