I keep getting a code 52030

If you are trying to connect with a wireless router, This indicates a problem with your Wii communicating with your wireless router.
There are a couple things you can try/check to help fix this problem.

1 - Try using a different channel on your router and update your Wii to take to the router on that channel.

2 - If your router is using WEP (encryption), make sure your Wii is set to the same encryption.

3 - Make sure the MTU values on your router match those entered on your Wii.

Also note that if you make changes to your wireless router and you have a computer that uses that router too, you'll need to update your computer to match the new settings on your router.
