OK, well, the other day I was able to connect to Wi-Fi, and now I can't. Nothing has changed from my router, it just keeps saying, 'That network key is incorrect. For more information go to www.nintendowifi.com' etc etc. I've visited the website already...a dozen times. It gives me the error code 51300. Could somebody please help me? I am at my wits end but I want to access the GTS!
