As a temporary fix....If you just want to be able to play your Ds games after receiving this error...Just power on the DS...then go to settings...then turn OFF the WiFi option. (The wifi light will go off) You won't be able to take full advantage of some of the other modes that rely on wifi on the Dsi but...you will be able to play your games again without opening up the back hardware of the device. -2F™
