I know the reason.

Nintendo cut all Wifi for Black / White, and all games before it. The only Wi-fi battles you can now do are on X and Y versions of them game

You've received Error Code 20110 because you are using a discontinued feature.

In May last month, Nintendo shut down all Nintendo Wi-Fi features for the Gen IV and Gen V Pokemo games, and they can no longer be used anymore. Unfortunately, it will never open back up.

So now you can't use the features like GTS, but you can do stuff like trading and battling with someone nearby.

Sorry. :/

Hope I helped. :)

As of May 20th, due to Gamespy shutting down all their programs and services the Nintendo Wi-Fi Connection containing online features have shut down. Therefore , multiple online Pokemon titles are affected by it and have become inaccesible
