Error Code: 51300

The Nintendo 3DS system was unable to establish a connection to the router.

Are you using WEP security on your router?

  1. Log into the router using the default IP (consult your router's manual for assistance).
  2. If you are using 64-bit encryption, the WEP Key must be a 10-character key consisting of numbers or letters A through F.
  3. If you are using 128-bit encryption, the WEP Key must be a 26-character key consisting of numbers or letters A through F.
  4. The WEP Key must be a Hexadecimal (1-9, A-F, no other special characters or letters).
  5. Verify they are using the WEP Key in the first (#1) slot. Even though your router may have multiple slots, the Nintendo DS is only compatible with the WEP Key in slot #1.


Other suggestions:

  • Check for wireless interference, which can affect the signal strength to the Nintendo 3DS. To help minimize wireless interference, try the following:

    • Make sure that the Nintendo 3DS is within 30 feet of the wireless access point and facing in its general direction.
    • Make sure that any other interfering devices, such as microwaves and cordless phones, are turned off.
