My WiFi suddenly became very bad for no reason.

Yesterday, I was playing a PUBG match when suddenly, the internet became very slow. It was so slow that YouTube couldn't load.

Can someone please tell me what's wrong?

Have you tried rebooting the router and your pc?

run malware scan...on your router make sure it not open where people are leaching you.
