Running a connection test on your Nintendo Switch
The steps to run an internet connection test are the same for the Nintendo Switch and Nintendo Switch 2. Here's how to start the process:
- Navigate to the Home Menu.
- Go to System Settings > Internet.
- Select Test Connection.
The test will start immediately. When it finishes, you'll see a summary message noting whether it was successful or failed. Also included is information about your connection and the test result components.
Test result details
Every time you run a Nintendo Switch connection test, the console shares key insights. They include:
- Connection name: The name of your internet connection (if there is one)
- Service set identifier (SSID): The name of your Wi-Fi network
- Summary result: The overall outcome of the internet connectivity test—Success or Failure
- Global Internet Protocol (IP) address: Your network's IP address
- Network address translation (NAT) type: A grade ranging from A to F, with A being the best, describing your network compatibility with other players
- Download speed: How quickly your Nintendo Switch downloads data it receives
- Upload speed: How fast your data is sent over the network
Pay attention to the summary result and NAT type. A successful test means your device has a fast internet connection. And with a NAT type A or B, you're ready for co-op gaming with your friends.

What to do if your connection test fails or shows slow speeds?
You've run the tests, and the results were less than stellar. To improve your connection speed, try these quick fixes.
Restart the router
If your Nintendo Switch won't connect to Wi-Fi (or it's slow), reboot your router.
Unplug the device from its power source and wait 30 seconds, then plug it back in. Wait two minutes for the router to re-establish a network connection with your devices.
After rebooting the router, try running the internet connectivity test on your Nintendo Switch. If your console passes the tests, you're ready to game.
Check for interference
The further away the router is from your Nintendo Switch, the greater the chance of network interference. Things like walls, metal items, Bluetooth®-enabled devices, and electronic gadgets can slow your internet speed to a crawl. If possible, move your router closer to your console and disconnect any internet-enabled devices you're not using.
Switch to a wired connection
A wireless connection is the gold standard for accessing the internet. But if your connection is still slow, try joining the Nintendo Switch and your router using an Ethernet cable. The cable bypasses interference sources and may boost connection speed.
How to check your connection results
NAT type, upload speed, and download speed are core components of your test results. Use these tips to decipher what they mean.
NAT types
Nintendo uses an A through F grading system to define your NAT type.
The NAT types determine who you can connect with during co-op gaming. They're a reflection of your network and router settings. Nintendo's ratings fall into these categories:
- A, B: Open NAT type
- C: Moderate NAT type
- D, E, F: Strict NAT type
If you have an A or B rating, you can connect with anyone during online gaming. A C rating allows you to join with other moderate and open NAT types. But if you have a D, E, or F rating, you can only connect with open NAT types. Your console may disconnect if someone with a moderate or strict NAT type joins the game.
If your NAT rating is affecting online game connections, consider adjusting your router settings. Check your router's user manual for guidance.
Upload and download speeds
At a minimum, Nintendo recommends a 3 Mbps download speed and 1 Mbps upload speed to avoid lag. With speeds that meet or exceed those standards, you should have smooth gameplay. If your speeds fall below the recommendations, try plugging in an Ethernet cable to boost the connection.
