arul.singh23 , via OnePlus 9R , Jan 28, 2022 : My Network speeds used to bottle down to absolute zero even while scrolling through Instagram or opening another app which needs to be constantly refreshed and used internet. So I found the DNS settings today and it was set on Automatic by default. I turned it off and issue just vanished. As you can see I have switched to Google DNS network. Both DNS off and Google DNS works really well but as soon as you switch to automatic DNS the network speeds are just not stable even on a 200Mbps Internet. I hope this might help others facing this problem.
