Welp, it looks like we're no longer able to get online for the Call of Duty Wii games unless you mod your Wii. Nintendo have adjusted something with the online configuration that has messed up the games that were still online. Here's a few links on how to get around this error code -
ERROR CODE: 23400, 20100 FIXED! Play Call of Duty On Wii in 2020! CoD WaW, MWR, Bo1, Mw3 Working! - youtube.com/watch?v=kMtNe6c9pPY
MW3 Wii: Fix for Error 23400 using USB Loader GX **updated description: another link** - youtube.com/watch?v=kUMEm9wEFxM
