Are you having trouble with your Nintendo Switch NAT Type? You aren’t the only one. In this article, I explain the issue I had and how I fixed my NAT Type D to NAT Type A.

The Nintendo Switch is a great console and I love being able to use it anywhere. I am more than comfortable with playing games with Single-Player Campaigns but I have started playing more and more online. It has only been the last 8 months or so that I have had Fibre optics installed in the apartment and I usually relied on mobile data by using my phone as a WiFi Hotspot.

It worked well enough for me but occasionally it would time out if somebody called me which, is not so good when playing online as I would get kicked out of matches. After getting a relatively good deal on getting home internet in the household, I thought I would have a fast and steady connection that will serve me well (No more getting kicked out of matches). However, while the download speed was really fast, I could not connect to any matches online at all. It was fine when using my mobile data but when connecting to my home internet, no luck at all.

This is when I decided to check my connection settings and low and behold, there was a big difference between my mobile data connection and my home internet. It was the difference in NAT Type. My mobile data had NAT Type B whereas my Home internet only had Nintendo Switch NAT Type D. So what does it all mean? Well, the better the grade of NAT Type you have, the better more possibilities of matchmaking you will have and the more stable your connection will be.

Nintendo Switch NAT Type

So what is NAT? Well NAT which I only learned myself a few days ago is as Wikipedia puts it:

Network address translation (NAT) is a method of remapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device”

Basically, the way I interpret NAT is that it allows your Nintendo Switch to communicate with other Switch Consoles and vice versa. This is necessary when playing online as the Nintendo servers have to send and receive data between Switch consoles so that all participants can respond accordingly to what is being shown on their screens. (does that sound right?).

Improving Nintendo Switch NAT Type

So, I went about trying to improve my Nintendo Switch NAT Type on my home internet. I thought that maybe a LAN adapter for the Switch might do it but that wasn’t the case. It didn’t solve anything so I looked online for other solutions. I found the Nintendo America support site which had a possible solution to my Nintendo Switch NAT issue. The site mentioned using a static IP address and using Port Forwarding to open all the ports on my router.

These solutions may have worked for most people but my router was just not having it (I have a Sagemcom F@st 5655 v2 AC router). Another option that I found online was to set my IP address in the DMZ (De-Militarized Zone) of my router. The problem with that is even if it did work, It would leave my Nintendo Switch vulnerable to serious cyber security risks. I was beginning to run out of options.

I had only one option left, to call my Internet Service Provider (Yoigo). I told them about my issue and they said that I would need to wait 24 hours and I will get a text message that will tell me to turn off my router for 3 minutes and then turn it back on. Unfortunately, this was over the weekend which means that the 24 hours were over a “working day” meaning I would have to wait until Monday or Tuesday for the text message.

Monday came and around mid-morning, I got the text message. I turned off my router and waited well over 3 minutes to make sure I didn’t turn it back on early. When I did turn my router back on and waited for it to fully boot up, I also turned on my Nintendo Switch to test the connection. Success! Not only did I no longer have Nintendo Switch NAT Type D but It had also been improved to NAT Type A.

I suppose what I am getting at, is that if you are having trouble with your own internet connection and Port Forwarding didn’t work for you, perhaps getting in touch with your internet provider could help fix the issue you are having and improve your Nintendo Switch NAT Type.
