Connecting from a hotspot:


  • The access point at the hotspot may not be experiencing problems. Ask the staff on site if their Wi-Fi network is up and running.


  • If the hotspot's access point has a built-in firewall or other security that interferes with the necessary transmissions from the Nintendo DS, then the access point will not be compatible with the Nintendo DS.


  • Try another hotspot.
