For the past week when I try to use YouTube every video wont load or play very slow at 144p no matter what browser. My internet is fine as i get 28 mbps down and 4.5 up. Also other streaming services such as Twitch or daily motion run fine. This problem is only happening on this one computer, every other device in my home works fine. I think it is a problem with my computer as i recently tried using my brother's phone's hotspot to connect to but still videos wont load.
Things that i have tried to do to fix it:
Clearing Browser Cache
Restarting Router, Computer, Wifi Card
Trying Safe Mode
Turning Off Firewall
■ Turn on hotspot from a device which the site can load from.
■ Connect the problematic computer to the hotspot.
■ Load youtube on the computer.
■ Now connect the computer back to the usual wifi. Try surfing the opened youtube.
