The title says it all, I don't know when or how but for some reason my wifi has been randomly disconnecting specifically on my pc. It starts with the speed of the internet getting slower and slower then it says "No internet". It's completely arbitrary, I've reinstalled the drivers, restarted the router, reasted the wifi card itself but nothing works. I can circumvent the issue by switching between 5ghz and 2.5ghz but after a few seconds or minutes (If I'm lucky) it persists. 

While writing this post it even happened to me twice.
