Good day everyone,
My wifi connection has been rather moody since yesterday; it's funky because it all started with me trying to convert a video in VLC (the correlation is not very clear to me, although when vlc eventually failed to do it and just stopped, the wifi worked again). So it just won't connect at all, and then sometimes it will and the wifi will work, and sometimes it will just stop working but will stay connected. It's definitely not a problem with my router, because every other computer and device is working all smooth. Furthermore, the same thing is happening if i boot with windows (i have partitionned my HDD in two pieces, one with ubuntu 16.04 and the other with windows 10).
My guess is that maybe the wifi card is failing on me? it's slowly but surely stopping to fulfill its duty? What do you guys think? Here's a bunch of infos that you may need to understand the problem (sorry, i just don't...), and that another topic suggested to put. ( My wireless/WiFi connection does not work. What information is needed to diagnose the issue? ) Sorry if it's a bit of a mess in here, i'm putting it all... thanks a lot in advance!
(it misses some info i cut because of character number)
