I tried to connect to wifi with my ds a few days ago. I have a wireless router and my wii connected successfully. But whenever I try to connect with ds, it says "error code 52000, found access point but could not connect to nintendo wifi." I used the search for access point function and used my router. I successfully entered the WEP key, but it still doesn't work. And I was in my house, and internet was working with computers at the time. So I know my internet worked, what's wrong?
