Does anyone know why I'm getting this error code, I'm connecting on a Wired Connection via the Wii Lan Adapter, I used to be able to go out to any town that was open, but now something's happened, not sure what, but all my Wi-Fi games are giving me is Error Code 86420, I went to Nintendo Support site and it's giving me nothing useful, it said about Router Firewalls, and yet it's never and I do mean NEVER stopped me going out before, so if anyone knows why and manages to permanently solve my problem, I'll give them 3,000 TBT Bells completely free, but to get the Bells, it will need to be a permanent fix like it was before, I don't understand what could of happened, the last things I remember doing was.
1. Upgrading Picture Quality to 480i (Component Cable)
2. Upgrading to Wii Menu 4.1

Error Code: 86420
(Using a Nintendo Wi-Fi USB Connector? If so, click here.)
If you get error code 86420 only some of the time, chances are this is temporary and the issue will resolve itself. We encourage you to keep trying.
If you are consistently getting error code 86420 and you are unable to make a connection with other players, the troubleshooting below may help resolve the issue.
When does this error code appear? Occurs when looking for any match: If the error code occurs after the matchmaking process has started, it is likely an indication of a firewall issue with your router (wired or wireless).
Important Note: it is recommended that any changes made to the router are performed from a computer that is wired directly to the router.
1. Try disabling the firewall* (also called SPI firewall). Netgear routers have this setting located under the "WAN Setup" tab of the router settings page. Other routers usually have it located under the "Security", "Firewall", or "Filter" settings.
2. In order to solve this problem, you may consider adjusting your router's Port Forwarding settings*. If you need help logging into your router, you may check our router look-up page by clicking here (link) to see if your model number is listed. If you do not see your router on our list, you may select any similar model by the same manufacturer to find default log-in and setting information. If you are still having trouble, contact your router manufacturer or the company that provided it for assistance in accessing the router settings. For specific information about your router's Port Forwarding settings, please see your router's user manual.
Before you begin with Port Forwarding settings, you will need to configure your Wii's Internet Connection with manual information. For steps on how to do this, click here.
3. Locate the Port Forwarding settings in your router. If the router asks for an "Application" or "Service" name, you can assign it anything you wish, such as "Wii", "Wi-Fi", "Nintendo", etc.
* The starting port to open is 1, the ending port to open is 65535 (or as high as the router will allow).
* Protocols will need to be set to UDP only.
* Set the IP address for the ports to forward to the same IP address you assigned to the Wii.
* If there is a box to enable the settings, be sure it is checked. Apply the changes.
4. Try enabling the "DMZ"* feature of the router and setting it to the Wii's IP address (see the instructions above on manually setting up the Wii's IP address).
5. Ensure your router has the latest firmware installed. Visit your router manufacturer's website and look for any updated firmware that may be available (these are typically found under "downloads" or "support", or by searching for your particular model number). For instructions on how to properly update the firmware, please follow the instructions on the manufacturer's website or refer to your router's user manual. Using the "auto update" feature from your router settings page may not get you the most updated firmware.
6. Lastly, if you are using a wireless router, the error may be caused by interference, weak signal, or a basic setting on the router that needs to be adjusted. Please review our general router troubleshooting.
7. The error code may be caused by "chaining" multiple routers together on the network. "Chaining" might cause connection problems when trying to access the Nintendo Wi-Fi Connection. If you have multiple routers "chained" together, see if it's possible to connect the Wii directly to the first router on the network (the router that is directly connected to the modem). If this first router is maintained by an administrator other than you, such as many routers found in office buildings, apartments, or dormitories, then you will need to contact the administrator for assistance. If this is not possible, you may have to find an alternate way to connect online.

*While Nintendo provides this information for our consumers' use, it is up to each consumer to determine what security needs they have for their own networks, and to decide how best to configure their network settings to meet those needs.
Trouble Connecting to a friend?
If the above steps have not resolved the issue and you are trying to connect with specific friends, the problem could potentially be a firewall issue on your friend's network. Your friend will have to perform these troubleshooting steps with their home network.

Using a Nintendo Wi-Fi USB Connector?
If you are using the Nintendo Wi-Fi USB connector and this error occurs some of the time, chances are this is a temporary issue and will resolve itself. We encourage you to keep trying.
If the error persists there may be an issue with the security programs on your computer. Temporarily disable any security programs you may have and see if the error persists.
There may be an issue with interference or a weak signal causing the error. Ensure that the Nintendo Wi-Fi USB connector is within range of the console (30 ? 100 feet) and that there are no interfering devices in the area. If they are on different floors or in different rooms, try adjusting the position of the console in relationship with the USB connector.
Lastly, do you have a wired or wireless router connected to your computer? Try connecting your computer directly to the modem and see if the problem persists.

Real Solutions===========
Its possible that a computer in the area could be overriding said wii connection since you run on a lan wire instead of wifi. Your picture quality could possibly be the problem. Normally connection problems like this does not happen unless something new has been added. It might even be a bunk wire. You never mentioned testing said wire, they can give out as well. Disconnect the wire and try it on your computer. If you can get though, it isnt your wire, but that alone knocks off about 80% of possibilities.
