I have direct tv and I am trying to hook my wii up so I can watch netflix it is giving me an error 51420

The Wii has to be hooked up to the tv you want to watch Netflix on.
It wont work from another room.

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.

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.

Sometimes this happens because servers go down for nintendo. If this problem persists it might be caused by a third party adapter that is used to connect your wii to the internet.

With the Wii you can only watch Netflix movies through the instant queue. In order to do this, you must request the Netflix CD for the Wii online and write down the code that is given to you when you do so. When the CD arrives, put it into the Wii (Make sure you have a working wireless connection to the Wii) and enter the code you wrote down. You should be good to watch any movies through the Netflix instant queue on your Wii. The Nintendo Wii cannot otherwise play DvDs. Anytime you want to use Netflix on your Wii, you must insert the Netflix CD for the Wii, so be sure to keep track of it! Let me know if you need anything else!

Error code 51030 means you Wii is unable to connect to your wireless network.
Try unplugging your modem and wireless router, then plugging them back in after a couple minutes.
While you're waiting for your modem and router, delete your network setting from your Wii, and set them back up once your router and modem are back up.
Your wireless router's setting might have changed and your Wii might not be able to properly connect.
