WonderCorner is a Wonder Trade/Multitool server for the Generation 4 and 5 Pokemon games.
(If you've connected to Wiimmfi or kaeruWFC before, skip to step 3):
  • 1) Go to your Nintendo Wi-Fi Connection Setup*->Options->Erase Nintendo WFC Configuration**
    • *If using a DSi or 3DS, you must do this within a Nintendo DS game, not System Settings.
    **If your DS has connected to official servers before, this will delete the data used to connect to the official WFC from your Pokemon games when you first log on (Pal Pad friends and, for Gen V, rating battle rankings). However since the official service is discontinued, this data won't work now to begin with.
  • 2) Reconnect to your router on the DS, as the above step will erase it.
  • 3) In the router connection you set up, set the primary DNS and secondary DNS to 167.172.207.124
  • 4) Save settings and exit configuration.
  • 5) Connect to the GTS. This will connect you to WonderCorner, as well as register you for kaeruWFC if not already signed up.
    To trade, first deposit a Pokemon. The level of the Pokemon you request in return will correspond to the appropriate channel.
    The species selected does not matter, as the returned Pokemon will not correspond to your request. Gender, however, is used to select subdomains.
    Then, by clicking summary (or by logging back in), you will receive a random Pokemon in the database inserted by someone else.
