Nintendo WFC Connection Problems (Error 61020)

Is your setup:
                                                                                                 DS Lite
                                                                                                  /
               Internet - (wire) - XP PC - (wire) - USB Adapter - (Wireless)
                                                                                                  \
                                                                                                  Wii

Or are you behind a router?

Can you connect in game at all - even if you lose the connection?

Does the test connection work?

What distance from your PC are the consoles?

Are there any other wireless devices in range?

That seems to be the way my setup is, unless you count the cable modem between the internet and pc.  I am not behind a router.  In the game, it tells me that I have connected to an access point, but couldn't connect to WFC.  The test connection works when I setup my connection before starting the game.  There are no other wireless devices in range.  It seems that it can connect, but loses the connection before it can do anything in the game.

Any ideas?

The problem may be that since you don't have a router, your Wii and DS aren't able to get their own IP addresses. Most ISPs these days only provide each subscriber with a single public address.

Also, what kind of wireless adaptor are you using? Is just a regular wireless PCI Card or USB adaptor or is something specifically from Nintendo?

I am using the Nintendo USB WiFi Adapter.  I've tried assigning them an IP address on my network and enabling Internet Connection Sharing for them, but that doesn't seem to work either.    I don't think it's becuase of only having one IP address from my ISP, because there are tons of people with these things that aren't having any problems.  Does that help?

Just a suggestion. Turn of Norton all together and try your connection. Every place that I can see or find about this problem points into 2 places. Router or Nintendos Connection is temporarily down.

Some users resolutions to this problem are:
- If router involved upgrade firmware
- temp disable firewall
- change access point speed from auto to a lower speed, ie: 11mb or even slower
- Wireless security should be changed to WEP instead of WPA


Also here is some blurbage from Nintendo's Site:
Error Code: 60000-69999

Our experience shows that error messages within this range are typically caused by temporary network outages with the Nintendo Wi-Fi Connection. If there is a problem with the network, our technicianýs will work to get the service back up as soon as possible. Please retry your connection later.

If you are connecting to the Nintendo Wi-Fi Connection for the first time, or the problem has not resolved itself after a few hours, there could be an incompatibility with your wireless home network. You may want to try the following:

* Ensure your router has the latest firmware installed. Visit your router manufacturers website and look for any updated firmware that may be available (these are typically found under downloads or by searching for your particular model number). Contact your router manufacturer for additional assistance.

* If your router or modem has a built-in firewall, you may want to try and lower the security settings*, as they could be interfering with a successful connection. How to do this will vary brand and model, so consult the manual or the manufacturer of your router or modem for assistance.

If after trying the above steps you are still unable to successfully login or play on the Nintendo Wi-Fi Connection, it is possible that your wireless home network is not compatible with the Nintendo DS or Nintendo WFC. We suggest purchasing a compatible router (click here for a list of routers weve tested and ranked), or the Nintendo Wi-Fi USB Connector. (Please note that if your modem is blocking the connection, the USB Connector will not work.)

Don't forget that NWFC needs free access to ALL your UDP ports and TCP access to 80, 443, 28910, 29900, 29901 & 29920 so you may still have Windows Firewall or other security settings stopping the WiFi adapter drivers getting out of your system.

Nintendo tools for checking your system:
============================
1) Test your network is OK:

2) Check you are not firewalling the connection:

3) Make certain you are using the latest drivers for the adaptor:

I've tried it with both Norton Firewall and Windows Firewall completely turned off, but to no avail.  
How do I change the access point's speed?  
I don't have a router of any sort.  I don't think I can change the wireless security on the Nintendo adapter.  If so, how?  
The only wireless device I own is the Nintendo USB WiFi Adapter, the Nintedo DS, and the Nintendo Wii.  

Sorry not much more can give to this. In your case your scenario should be:
Internet/Modem (log in to modem to see if there is any routing capabilities)
-
PC (Disable Windows Firewall and Norton for testing purposes)
-
USB WiFi Adapter (Not much to it, but confirm connection and internet access)
Also Internet Sharing is enabled
-
DS/Wii (Confirm with the Wii you have connection)

Last resort, call Nintendo and tell them you are having problems with your Wii AND DS connecting with your USB WiFi. All Nintendo products and if no one here was able to help, then maybe they have some insider information that can help.

Another thing to make sure of, is that you are not surrounding your Wii/DS with other devices that could interfere with the frequency, such as microwaves, cell phones, cordless phones. These can jack up the frequency and can cause connection issues.

Honestly, I think you're dealing with problems that are directly related to the Nintendo Wi-Fi USB adaptor.  I think it would be best if you spent the 40 bucks or so and got a decent Wireless G router from Dlink or Linksys.  In my experience, the Wi and the DSes in my home do MUCH better now that we're all setup on a dedicated router with the windows firewall turned off.  The thruput is better and we're not having any of the issues that we had before with games like MarioKart DS or Pokemon Diamond/Pearl just disconnecting randomly.  A router will help secure your home network better (humble opinion) and with the norton security turned off AND windows firewall relaxed, your computer will be happier and your wireless devices (the Wi and the DS) will be happier.

Just remember that there is NO support for the DS when you use higher level security on your wireless network.  Stick to the WPA it works well.

Good Luck.

Also make sure you update the firmware of the router you get, It will help a lot.

I never got this to work.  I finally just upgraded my network to wireless and now I don't need the adapter.  Thanks for your help though.

I think Jstncase actually posted the solution here {http:#a20601291} & should get credit
