Nintendo Shutting Down Wi-Fi Connection for DS and Wii

At some point in the next 24 hours, Nintendo is turning off online functionality for Wii and DS games including Super Smash Bros., Mario Kart, and Pokémon. You'll no longer be able to use the WiFi on Wii and DS to play those games online, download new content, or access leaderboards.

Online play for Wii U and Nintendo 3DS games will be unaffected (aside from the Wii mode on Wii U and Nintendo DS games on Nintendo 3DS family systems). Other online functionality, such as access to the Wii Shop Channel, the Nintendo DSi Shop and video-on-demand services, are also not affected at this time.

You'll still be able to watch video services (like Netflix) and access the Wii Shop. The full list of affected games is below. 

Note: Game functionality that does not require an Internet connection will remain unchanged.
