Error Code: 20100
If you receive this error when attempting to connect a game online, please note that as of May 20, 2014, certain online functionality offered through Nintendo Wi-Fi Connection is no longer accessible. The discontinued services include online play, matchmaking, and leaderboards for many Wii, Nintendo DS and Nintendo DSi games. You will receive this error code when attempting to use an online feature affected by the end of these services. For more information regarding the end of these services, click here.
If your are using a different online service, there could be a problem with your home connection. Try the following:
- If the error appears when using Netflix Instant Streaming for Wii: In some cases, we have found that deleting the Netflix save data (how to), then re-activating your Netflix account on your Wii console (how to) will resolve this issue.
- Ensure your home internet connection is working properly. Use a PC that is attached to your home router and visit a website that you have not been to before, in order to check that the connection is currently working.
- Try adjusting the "Channel" your wireless router broadcasts on. We highly recommend setting your wireless router to either channel 1 or 11. This can potentially increase stability. For information on accessing your router's settings, click here to select the brand name and model number of your router (if available).
- Within the Wii's system settings, erase the current connection file you use to connect your Wii online, and set up a new one. To do this, access the "Internet" option from the Wii settings. For step-by-step instructions, click here.
