If the above procedure doesn’t work for you, there’s probably something else that’s hindering your speeds. You can see the results for yourself below: While trying to download Horizon Zero Dawn game, we observed that the ETA was cut down by half after switching to Google’s DNS and MTU value set to 1473. The download speed almost doubled and the upload speed was almost 10 times better. The WiFi network provides an internet speed of around 5-7 Mbps, so the improvement in speeds was quite significant in our case. If the procedure didn’t work out for you, it’s something else that’s hindering your speeds. Considering Google DNS and OpenDNS servers are two of the fastest DNS servers in the world, it will most certainly be faster than your ISP’s DNS servers.

The reason why you get this improvement is because in certain areas, the ISP’s DNS servers may generally be crowded. Well, it’s as simple as that, you should notice a considerable improvement in your download speeds after you’ve done this. Then, wait for the speed test to complete, it usually takes around a minute.
