I am a brand new french user of Linux Mint (I was using Ubuntu or Voyager before).
I've made multiple searches for this problem, but I did't find any answer.
Each time that I'm watching videos online on Youtube, Dailymotion or other site, my wifi turns off. To make it back, I have to press the off button in the applet, then, to press it again to turn it on.
Here are some informations about my computer, hardware, configuration...
