Pokemon soul silver wifi connection fails

[Glacialeye]

Well I was playing the game but then I tried to see if I could play online and then there was an error on the screen that said like error 20110 and that Ninentdo wifi network is not available for that game. So I was wondering if there is something I can do to fix it or not. Thanks

Nintendo DS wifi doesn't work even on a real DS now, so it's a real hardware issue and not a problem with your emulator (there used to be a version of DeSmuME that supported wifi, but it became useless when it was discontinued on the real console).

Nintendo Wifi connection is no more, you must use a unofficial server to get online with a DS and Wii now.
