If you received the "Grant Permissions" screen of the installation tool, then the installation was successful. If your installation was successful and you are able to connect to the Nintendo Wi-Fi Connection, but you are unable to get matched up with others to play a game, or if you are getting error messages on your Wii in the 52000, 53000, or 30000 range, then you are likely experiencing problems with your computer's firewall.

Just in case , if you have Windows Vista, you must have version 1.06 or higher of the Nintendo Wi-Fi USB Connector software. Click here to download the latest version.

If during the Nintendo Wi-Fi USB Connector installation process you are unable to get to the "Grant Permissions" screen, then the following troubleshooting on this page may help get the installation completed. The steps below are performed on your PC, or if/when necessary, your router.

Note: If you have a network setup where one computer with a modem is being used by other computers to access the internet, the USB connector should be installed on the computer with the modem.



Does the Setup CD automatically start when you insert it into your computer?

If the Setup CD does not automatically start up when inserted, the Autorun feature of your computer may not be enabled. If the set up window doesn't appear, on your computer, click the "Start" button, choose "Run," and then click the "Browse" button. Click on the CD drive the Setup CD is in and locate the Setup.EXE file. Double-click this file to begin the installation process.

Ensure that you have rights to install software on the computer
Windows only allows users who are granted "Admin" rights in their profiles to install software. This includes the software necessary to install the Nintendo Wi-Fi USB Connector. To determine if the profile you are using has "Admin" rights:
Click the Start Button and select the Control Panel.
Select "User Accounts."
A list of all User Accounts are displayed. Users listed as "Administration" level are able to install software.
If the profile you are using does not have these rights, you will not be able to install the required software. Please contact an individual with "Administrator" settings for assistance.
Make sure you have the most current install software
Click here to check our Nintendo Wi-Fi USB Connector software downloads page. Upgrading to the most current software may solve some installation and connection issues. (Note: if you already have Nintendo Wi-Fi USB Connector software installed, be sure to uninstall and reboot your computer before installing another version.)
Check to see if there might be an IP Address conflict between the router and the USB connector :

Verify your Default Gateway IP on your computer:
Click the Start button
Click "Run."
Type CMD and click Ok.
The Command Prompt (small box with a black background) will appear. After c:\> type IPCONFIG/ALL and press Enter. Your Default Gateway IP will now be displayed.
If the Default Gateway displayed is either 192.168.0.1 or 192.168.1.1, you will need to find the IP Address in you router's settings and change it to 192.168.2.1

Important! If you have any other devices that utilize the router, you will need to update the IP Address on each of these to match the one you entered on the router.

If the IP Address needed to be changed, power down your computer and, if you have not already done so, disconnect the USB connector. Being sure to leave the connector disconnected, power on the computer and go through the installation process again.
If the IP Address does not need to be changed, or if the installation fails, please keep reading.


Check Local Area Connections to determine what the Internet Connection Sharing (ICS) options are set to.
Which option is correct will depend on how you have your computer set up. Unless indicated otherwise, make sure the USB connector is connected to the computer throughout these steps.
To perform the following steps, you will need to access your computer's Local Area Connection screen. To do this, click the Start button, select Control Panel and click on the Network Connections option.


Adjust the ICS options as needed:
If one Local Area Network is listed on the Local Area Connection screen, other than the USB Connector:

Right click on that connection, select Properties, and then the Advanced tab.
If the ICS options are enabled, uncheck all boxes under the ICS area to disable them.
If the ICS options are disabled, check all boxes under the ICS area to enable them.|

If two or more Local Area Networks are listed on the Local Area Connection screen, other than the USB Connector:

Right click on the "Network Card," select Properties, and then the Advanced tab.
Uncheck all boxes under the ICS area to disable them. (If you are getting an Internet Connection Sharing error, the ICS settings were most likely enabled (checked).)
Uninstall the USB connector through the Device Manager.
Make sure you have the USB Connector plugged into your computer.
Click the Start button and select Control Panel.
Click "System" and select the "Hardware" tab. Choose "Device Manager."
Next to "Network Adapters," click the "+" to expand the list.
If the Nintendo USB Connector is in the list, right-click it and choose "Uninstall."
Perform the DEVREMOV process.
Make sure you have the USB Connector plugged into your computer.
On your computer, click on the "My Computer" icon (found in the Start menu or sometimes on the desktop), and right click on your CD drive containing the Nintendo Wi-Fi connection Installation CD, and choose 'Explore.'
Open "NintendoWFCReg/SoftAP." Within there, double-click the DEVREMOV.exe application.
During the course of running the DEVREMOV program, you will see three windows pop up successively.

The first will have a series of question marks. Click "Yes."
The second will have a picture of wires and lights moving on it while the DEVREMOV utility uninstalls the internet connection sharing for the Nintendo Wi-FI USB Connector. This will disappear on its own.
The third will also have several question marks on it. Just click "Ok."
At this point, remove the USB connector from your computer.
Check the "Programs" list and, if the "Uninstall" option for the connector is there, run this process.
Click the Start button , and select "Programs."
If the Nintendo USB Wi-Fi Connector is listed, click on the "Uninstall" program to remove it.

Check Add/Remove Software on the computer and, if listed, remove the USB connector.
Click the Start button, and select Control Panel.
Open "Add/Remove Programs."
If listed, select the Nintendo Wi-Fi connector from the list, and click "Remove."
Follow the prompts to uninstall the program.
Remove the installation CD, power down your computer, and disconnect the USB connector if it is still connected. Being sure to leave the connector disconnected, power on the computer.
Once the computer is on, plug the connector into the USB port.
If Windows does not detect the connector as a new device and prompt you to install it, all components have not been removed from the computer. Complete steps 2 through 5 again.
If Windows does detect the connector as a new device, remove the connector from the USB port and go through the installation process again.
If the installation is still unsuccessful:


There are likely settings on your computer that are making it incompatible with the installation program. Please call Nintendo at 1-800-895-1672 to discuss additional options.
