It's really disappointing that Nintendo haven't fixed it after almost 2 days now, it's affecting the player numbers of some of these games (Modern Warfare 3, at the time of making this post, has no players online, when normally you're at least able to find 1 room at this time)

Funnily enough, this means games that are discontinued don't show the discontinued error message with error 20110, they show error code 23400 too.

Well, it seems Nintendo had broken the codes with another server-side change (because I was setting the second host header to NULLs...) so I've updated them on the website to instead use 41414141 rather than 00000000.

and then? what do you do with these codes? can't do a mini tutorial on how to use them? many lay people besides me will have this doubt when they know this.

Hello guys. I need some help with using codes. I've recently installed Rock Band 3 DLC but I can't download the songs to the game because of this Error. How can I apply the codes? I'm a real beginner. I'd appreciate your help a lot!

Unfortunately, the Wii Shop no longer functions, so you can't install the DLCs through the game anymore, not even with the help of these codes. Sorry.

Apologies in advance if this is the wrong place to ask, as this isn't directly related to Wiimmfi's servers, but I noticed that Call of Duty: Modern Warfare Reflex throws out error 20100 (Unable to connect to the Internet) when attempting to connect online using InvoxiPlayGames' code and RiiConnect24's DNS (164.132.44.106). This is the only COD title I am able to test, and other Wiimmfi games work fine. Switching over to another Internet Connection profile that uses Google's public DNS Servers allow the game to connect.

I recall that the COD games would connect before with RC24's DNS, so I don't know if there was a recent change made to RC24 that is preventing the game from connecting by design, and just wanted to get some clarification if that is the case.

Thanks.

RiiConnect24's DNS likely changes Nintendo's Login Server (naswii) to direct towards Wiimmfi's instead, rather than to official Nintendo servers. You can't play Call of Duty using the fix codes if you're using RiiConnect24's DNS.

MWR online seems to work now when the Ocarina/Gecko codes are disabled. Did Nintendo update their Wii login server?

I just tried it, with all of Modern Warfare Reflex, Modern Warfare 3 and Black Ops 1 - I still get error 23400 unless I use these codes. Are you sure you disabled them?

Perhaps it may be an error on my end.

I am launching the game through USB Loader GX, and I have Ocarina turned off for the game and private server off as well.

Just now, to make sure it wasn't reading codes stored off of the SD Card, I downloaded a new copy of USB Loader GX on to a USB Drive and removed the SD Card from the console (there are no codes on the USB Drive, and normally I launch USB Loader GX off of the SD card), and I connected online just fine. This was with Google's DNS, if that makes any difference.

Does the MWR save file keep any of the changes that the codes trigger even when they aren't used later on? Or does the version of USB Loader GX that is linked on the Wiimmfi home page enable codes even when they aren't present?

I even tried to load a non-CoD game as well off of the new instance of USB Loader GX on the USB Drive, with all of the Wiimmfi/Private server settings set to OFF, and was NOT able to get online, encountering the high volume traffic error instead, but MWR connects just fine.

EDIT: Reason for testing a non-CoD game was to ensure that USB Loader GX wasn't applying some sort of fix even the settings were set to off.
