Wi-fi Problem

I have a Wi-Fi Usb connector and I use it to play mario Kart Ds and Pokemon Diamond worldwide (mario Kart to race vs others and Pokemon Diamond to battle and trade pokemon). One day I wanted to play mario Kart with Wi-Fi and I started searching for someone who was searching too in the game. Then I found someone and started racing. The other player game wasn't normal and although he was behind me he was appearing in front of me. Then I overtook him and he was behind me again. Then his and car dissapeared and appeared in front of me. This was happening again and again and finally he won. He used an Action Replay because of the "in front of me appearence" and because of something else. My favourite race is Rainbow road and we were playing Rainbow Road. That guy was falling all the time but one second after he fall he was normal in the race again like he hadn't fallen before. Ok this a past story. BUT! Now when I try to Connect to Wi-Fi Connection, it starts saving and then it stop saving and the game freezes. I have never used a cheating machine like Action Replay and I hate cheating...I think that that guy has ruined my game with his Action Replay...The Wi-Fi Usb Connector doesn't have a problem because I use it every day to trade pokemon and it works....

hey i've also witness that cheat where the player falls and then appars back in front its happen on the kart wii too so i just quit the race,but theres no way that his cheat could have affected ur game so something else is wrong with ur game.

Sure? Just the same day after the battle I had the problem...

well officially since yesterday i have no wifi anymore cause it wasnt working then i tried to uninstall it and when i tried to instal the new version nintendo wfc connection 1.06(cause i have a nintendo wifi usb connector) from nintendo that will help it work on windows vista,the problem is that when tis on the last steps to download the newer program it tells me that the file already exists or something then it doesnt finish downloading the new program,and i tried finding the file thats already there, i delete it but when i try to install the new program it still says that the file is there
