1. From the Wii's main menu, select the Wii icon along the bottom left of the screen.
2. Select "Wii Settings".
3. Click the left arrow to get to Wii System Settings 3
4. Choose "Wii System Update"
5. Choose "Yes" to connect to the internet and perform a Wii system update.

This should remove the error and allow you to watch Netflix.

Hi there!
Error code 51330 on the Wii means that the password you entered into the Wii to set up your internet was entered incorrectly. You will need to go back into your internet connections settings menu on your Wii and enter the correct password/security key for your router. Please remember the security key is case sensitive.
Hope this helps!

Error Code: 51420 The Wii console is not able to connect to your wired router or modem.

1. If your connection worked previously, check to see if there is a Wii System Update that you have not aquired. To get the latest Wii System Update:
   1. From the Wii's main menu, select the Wii icon along the bottom left of the screen.
   2. Select "Wii Settings".
   3. Click the left arrow to get to Wii System Settings 3
   4. Choose "Wii System Update"
   5. Choose "Yes" to connect to the internet and perform a Wii system update.
2. Make sure that you are using the Wii LAN Adapter made by Nintendo. LAN adapters not made by Nintendo likely will not work with the Wii console.
3. Check to make sure you are not running the Wii LAN Adapter from a USB hub (a device that connects multiple USB products through a single device), as this will likely not work. Connect the USB Connector directly to the modem or router.
4. Ensure that the Wii LAN Adapter setup is correct, and that the Wii LAN Adapter was connected with the console turned off.
5. Check to see if the ethernet cable you are using is not working properly, by connecting another ethernet cable from your router/modem to the Wii LAN Adapter. If the connection works using a different cable, then the problem was with the first cable.
6. If possible, try another Wii LAN Adapter. If you are unable to try another Wii LAN Adapter, or are still receiving this error code, please call 1-800-255-3700 for assistance.

That error code means that your Wii loses connection to the internet. Here's a link to Nintendo's website that should help fix your problem.

I had a friend with the same issue. I just modded his wii and then he backed the games up to a hard drive and they played perfectly without an update being needed. The best place to get your wii modded is www.wiihdmods.com

Error Code: 32017 There appears to be an issue with updating your Wii console.

Knicked this from a forum site:
"I don't know if it's coincidence but I was having the same problem. When the error message came up it said that I should check my internet settings. So I went to wii options-->wii settings-->wii system settings 2-->internet-->agreement/contact.

I re-accepted the terms and conditions for the shopping channel and then went to try the update again. It worked. If you are still experiencing problems with the update you might want to try this."

The fault is with the update not the console so don't worry too much
