I have pokemon pearl and am trying to connect back to the Nintendo WiFi to check on a pokemon I had put up for trade. So, I have successfully connected before (and at this point with these settings) and now I can't. At first, I thought maybe the settings had changed or something so I erased my previous settings and set up a new one, but it keeps on giving me the error message 52100, and I just want to know if anyone out there knows how to fix it?
