If downloads are excruciatingly slow or you’re lagging behind in Mario Kart 8 Deluxe, it doesn’t necessarily have to do with your WiFi or Internet connection. It could also just be that the default Internet settings stored on the switch don’t harmonize well with your network hardware.
Next, we will focus on the MTU value, which regulates the size of the data packets received or sent by the Nintendo Switch. A manual setting can reduce a few Mbits of upload and download bandwidths or reduce latency in online games.
All important information about the MTU value of the Nintendo Switch
Therefore, your switch’s MTU value should not exceed 1472 bytes. With Internet connections that are made through a DSL modem, you must subtract 8 bytes again, then you end up with an MTU value of 1464.
Here is the MTU value of the Nintendo Switch:
- Check the “Internet Settings” menu item in the system settings under “Internet.”
- Select your Wi-Fi network.
- Go to “Change settings”.
- A little further down you will find the MTU value.
If you set the value too high, the data packets must be split, which increases the latency of the Internet connection. Therefore, you should not immediately enter the ideal value of 1472 or 1464, but instead set it lower or directly measure the maximum MTU value supported by your network.
This is how you find out the MTU value that is suitable for your network on your smartphone
Due to technical peculiarities, many network configurations transmit data packets with less than 1472 bytes. You can determine the exact value quite simply, but you need to download an application with a ping test on your smartphone.
We can recommend PingTools Network Utilities for Android smartphones and Ping – Network Utility for iPhone because they provide the required range of functions.
Now follow these steps:
Any tips for setup? A good starting point is the maximum value of 1472 bytes supported by many networks. If the sent data packets are received, you can immediately transfer them to your switch as an MTU value.
If the test fails with 1472 bytes, you need to reduce the packet size step by step to get closer to the point where the sent data packets reach the destination. A successful test in the PingTools Android app looks like this:
Similar procedure on PC
If you have a Windows PC, no additional download is required. you go to the Magnifying glass next to Windows iconsearching “cmd” and open the “Symbol of the system”. There you give the order “ping google.de” with the additives “-F” Y “-l” a. This is followed by the desired packet size you wish to test. Here, too, it’s best to start with 1472. If the test fails, you should reduce the number and continue testing until you get a hit.
Snake oil or royal help?
There are some reports on Reddit that in certain games, online mode can be played with less lag when the MTU value is increased. We haven’t been able to confirm this for any games so far, but we can at least measure a small difference in download times.
On average, the Nintendo Switch downloaded Super Mario Odyssey one minute faster at the same distance from the router. It is therefore a minor reduction, if anything, which could also be explained by measurement tolerances.
However, various speed tests via wieistmeineip.de actually suggested a consistently higher download rate with an MTU value of 1472. It was regularly up to 20 Mbit higher than with the standard MTU of 1400, with the speed of Differences in load and latency times, however, are negligible. However, these steps should be taken with caution, as they required access to a community project server.
We couldn’t find any drawbacks in any case, so we recommend adjusting the MTU value, as long as it matches your network.
Have you heard of the ominous MTU value and made adjustments? Did they help you?
