Need some help guys. I am trying to connect my wii to the internet through the Nintendo Wi-Fi USB connector. I have the connector installed and it is upto date. My Wii connects to the Nintendo wi-fi connector fine, but it keps coming up with error code 52040.

any help is much appreciated

 Also my DS connects to the internet just fine through the the wi-fi connector.

Have you performed a wii system update?

Not sure if this will help, pulled it off Nintendo. I had no trouble with my wireless router, it is a netgear.

Error Code: 52040
The Wii console is not able to connect to Nintendo Wi-Fi USB Connector.

Try uninstalling the Nintendo Wi-FI USB Connector software, and re-install. For step-by-step directions, including a link to the latest software, click here.
Does your PC have any security programs (firewall, anti-virus, anti-spyware, anti-adware, etc.) installed? If you are using the Nintendo Wi-Fi USB Connector, and have a software firewall or other computer security program installed on your computer, there may be additional steps you must complete to allow a successful connection.
"Trusted" Applications:
If your firewall or PC security program keeps a list of trusted applications (also known as a "trusted zone"), the following programs are installed with the Nintendo Wi-Fi USB Connector, and require internet communications. If prompted by your firewall or PC security program, add these to the list of trusted applications. This information may also apply to certain computer security applications, such as anti-virus, anti-spyware, etc.:

Nintendo Wi-Fi Connector USB (NintendoWFCReg.exe)
Setup.exe (when installing the USB Connector)
SoftAPInstDrv.bin
mdriver.exe
It is possible that your Internet Service Provider (ISP) is not compatible with the Wii console. For instance, if you need to login with a user name and password when you try to go online for the first time after restrarting your PC, your ISP is likely not compatible. Please contact your service provider for more information.
If you are still receiving this error code, it is likely that the Nintendo Wi-Fi USB Connector is not compatible with your current home network.

Is there any message along with the error. If so that would help alot. edit:nvm look ^

the error message reads 'Error Code:52040 Unable to connect to the internet'

The Nintendo Wi-Fi USB Connector has been discontinued...

Why are you using this and not a wireless router or the like? 

could be many a thing but here's some things to try

1. WEP kep - have you entered one, if yes ensure it's exactly 10 characters and only uses letters a thriugh to F (example ABBAFABBAF works very well).

2. Have you run the setup program that came with the dongle - this will ensure things like enable other computers to access the internet is selected.

3. Have you attempted to find settings automatically or entered them manually? I couldn't get automatic to work and got the manual to work.

4. Have you entered the MAc address in the software on the pc for the dongle? this is a list of trused sources that the software will allow access.

if none of these work then open the software and attempt the connection - there should be a list of mac addresses of devices attempting to connect, if it appears you know it's a security issue - if it doesn't it's not finding the connection at all.

@Words of Wisdom
Some people don't have wireless routers and it's cheaper to spend $35 on the dongle than $40 on a router. DUH!

The dongle doesn't use WEP.

More than likely it's a firewall related issue. Try disabling your firewall, and anti-virus, and see if it works. If it does, enable one at a time and see which one was blocking it and configure it accordingly.

Then again, I had this issue at the inlaws when I brought the Wii and my Dongle over. Where NOTHING I did worked, so who knows.
