But I went to the Nintendo website and searched error code 52000 and found the answer. They asked me
manually to put the default gateway, router ip address, etc, etc. http://www.nintendo.com/consumer/wfc...S&locale=en_US
But I guessed you went there too.
Likely cause: It appears that the security settings entered into the Nintendo DS are not the same as what your wireless router is set to allow, or your router is not able to assign the Nintendo DS an IP address.
How to fix: Make sure the security key and security type are entered into the Nintendo DS exactly as they appear in your router's settings; manually assign an IP address to the Nintendo DS.
