Summary
-
If you’re experiencing slow internet speeds or consistent buffering, it may not necessarily be your connection speed that’s the problem
-
It could be your default domain name system (DNS) servers that your internet provider gives you which are often slower, less private and unreliable compared to external alternatives
-
The one thing you should do is change your DNS provider to a faster and more secure external server which can be done at both the router level or on individual devices
-
This can reduce loading times and buffering and also improve privacy by encrypting your DNS traffic through DNS over HTTPS
-
It’s also a good idea to flush your DNS cache regularly by using the command prompt on a Windows device or terminal on a Mac
-
There are also a number of online DNS speed test tools which can show you the fastest DNS speeds for your location and particular device so that you choose the best option for your region
