If you are getting this error after completing a system update, this is usually because the console resets to using the first connection slot after an update. There are two things you can do:

If you know which connection file you were using before, you can select that connection file, then select "Use this connection" to change that to the default. You will need to do this each time they download an update.


If you don't know which connection file you are using, or if you would prefer not to update the active connection file each time, try to clear, and then re-create your connection setting in slot one before doing the remaining troubleshooting.


Check for interference that may be preventing a successful connection. Click here for tips.


Check to see if the router you are using is a known to be incompatible. Click here to view our list. If your router is known to be incompatible, we recommend using a different router if possible.


Make sure that the SSID (network name) matches exactly to what you have entered in the Wii console's settings. To verify:
Login to your router's settings (click here and select your router, if available, for information).
Look for the section for SSID (typically in the "wireless settings" area).
After you find the SSID (network name), verify in the manual settings of the Wii console that the SSID appears exactly as listed in the consumer's router. This includes making sure capitalization, spaces, or special characters match exactly.


Look up your router, if available, in our list of wireless routers, and check for any special notes that may be necesary to get the connection to work properly.


The router may not be assigning an IP address to the Wii console, and a connection using the "Manual Settings" may be necessary. Click here for help.


Your router may require a firmware update to work properly with the Wii console. Firmware updates can usually be found on the router manufactruer's website; consult the manufacturer for more information.

This error code usually indicates a problem relating to wireless security. Please try the following troubleshooting:

Are you using WEP or WPA security on your router?
Log into the router using the default IP (consult your router's manual for assistance)
Locate the "wireless security" section of your router settings and find the WEP or WPA key.
If you are using 64-bit encryption, the WEP Key must be a 10-character key consisting of numbers or letters A through F.
If you are using 128-bit encryption, the WEP Key must be a 26-character key consisting of numbers or letters A through F.
The WEP Key must be a Hexadecimal (0-9, A-F, no other special characters or letters).
If your router has multiple slots for a WEP Key, make sure the active key is the one in the #1 slot.
If you are using WPA, the Wii console is compatible with the following types:
WPA - PSK (TKIP)
WPA - PSK (AES)
WPA2 - PSK (AES)

If your WEP or WPA key is correct, then the problem might be related to MAC address filtering:
From the router settings, locate the "MAC address filter" settings (also known as "access control", "access list", or "network filter" depending on your router model).
If the Mac address filter is set to "enabled", then you must add the Wii's MAC address to the "allowed" list. You can locate the Wii's MAC address from the "console information" page (located under "Internet" in the Wii Settings).
If the Mac address filter was disabled, then continue troubleshooting.

If your connection was working previously, try power cycling your router and modem by unplugging them both from the wall. Wait a few minutes, and plug the modem back in. Wait a couple of minutes for the modem to initialize, then turn on the router. Try to connect the Wii console online and test for proper response. (Some routers may lose their connection to the Wii console while it is in Standby or turned off for a period of time. Check with your router manufacturer's website for the latest firmware, as there may be an update that will help prevent this issue from occurring in the future.)

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 the download speed.
