Nintendo DSi internet doesn’t connect anymore?
well, the internet for my DSi use to work. And when I went to Mexico it stopped working. It worked fine at the airport. Once i was in Mexico (Sayulita), it just didn’t want to work. I tried using my cousins Wi-Fi and when i went to system settings to choose the access point it showed up. With three bars. And even now, that im back home, it does the same thing, but once i choose the access point and the connection test begins, it looses all the bars. Then, gains all three bars and looses them. I get the error code: 052100-1. Can anyone help me, please ?
The point is, it use to work, and now it doesn’t want to recieve internet ANYWHERE. because everyones else gets internet where i use to get it and i can’t. The place has 3 bars, and once the connection test begins, it doesn’t stop ’till it looses the bars and it use to stop when it had all three. Do i have to get it fixed?
