Understaing Maximum Transmission Unit (MTU)

MTU determines the maximum size of any data-packed that is transmitted over a network. The maximum value of MTU is 1500 bytes. It means that you can send a data packet of a maximum of 1500 bytes at one time from a device.

Best MTU for PS4

In general, the default value of PS4 is 1500 bytes, which is the maximum value. However, there are claims that if this value is reduced, the delay reduces. The idea behind lowering the MTU value is simple. If you send a smaller packet over the network, it takes less time to reach the destination. This, in turn, reduces the delay. And you will experience a seamless network connection without any lag.

This process takes a little time, but it’s worth spending, which helps you to reduce lag while playing.

Find the optimum MTU for your PS4

As we explained before, go to the MTU ‘Manual‘ settings and manually lower the MTU value. Now come back to the main ‘Settings‘ and go to ‘Test Internet Connection.’ Here, test your internet connection speed.

Repeatedly test your internet connection speed by lowering the MTU speed again and again. Stop lowering the value of MTU until you see ‘Packets are no longer able to be fragmented‘ on the speed testing screen.

The immediate MTU value greater than the MTU, which can be no longer fragmented, is the starting value for your PS4. You have to add ’28’ to this value, which gives you the best MTU value for your gaming console.

Now, again change the settings with the MTU value that you have found and complete the setup. Once you change the PS4, you also need to change the MTU in your Router settings.

Changing the MTU settings on the router changes from one brand to another. Here we have given the common steps that can be followed in general. If this doesn’t work for you, search for Changing MTU value with your brand’s name.

Step 4: Complete the setup and reboot the router for the changes to be effective.

Now the MTU value is changed on both your PS4 console and Router, and the internet speed might have improved.

Even though many people claim that changing the MTU value improves the internet speed, reduces that lag, there is no evidence that it actually improves the network speed. But there is no harm in changing the MTU value and see if it helps in enhancing your PS4’s performance.
