Then it's likely that the data doesn't go to the right destination. On the DS side you need to input a IP for the DS and for the connection to the router/SoftAP. Then if you are connected to the router and in the menu for the UDP Test app (Sorry I can't look up the right titles right now), there you need to change the ip to your pc's IP. Notes: Be sure that the DS IP isn't already in use, and that the Dest. IP is the right one. If you have specified a WEP for the router/SoftAP then it won't work, that's beacause WEP doesn't work for now (The app will tell you that the connection was successfull, but it won't work). BTW, there is already a thread for questions in this forum, so if it still doesn#t work ask there.
