I have an acekard 2.1 and have not having any problems connecting wifi my DS in my home ( even though I only get 2 bars when the router is right next to me, but that's not my question right now ). Now I wanted to play some Tetris online with somebody, but using the free wifi of a restaurant. When I checked for any access points, the DS found the one of the restaurant and everything was going smooth ( it was unlocked and had full bars ). Now when I saved the settings for that access point and decided to "test the connection" the full bars where shown, and then it changed to no bar connection ( red ), and then the message "error 53001" appeared. It said that I can't connect online using my ID or something like that. What is the problem and how can I fix it? Thx in advance.
