From the answer of the question's author which was originally posted in the question:

Make sure your Wi-Fi antenna is working (switched ON) by pushing the button with the antenna symbol on it as you can see in this image below. On my laptop the Fn+F12 keys turn the Wi-Fi ON and OFF.

enter image description here

This is quite a major problem: In Ubuntu, you can have the "physical" antenna turned OFF while having the Airplane Mode switched OFF. In this scenario you have no idea that your Wi-Fi is disabled, and that the only thing you need to do in order to use Wi-Fi is to push the antenna button on your keyboard as shown in the above image.
