So, my O3DS is working just fine with the wireless switch turned off, but when I enable it, it just get into a black screen like this: Warning: Spoilers inside! People on the web says the problem can be easily fixed by just removing and putting on the wireless module, but it didn't solve for me. So, I think I need to replace this module to make it work again. But could it be another problem, like a software problem? Or maybe it's just the cable that connect the motherboard to the wireless module (and if it is, where I can buy it?)? By the way, the wireless module of the O3DS is the same as the one of the 3DS XL? Edit: It looks like the 3DS doesn't even turn on with the adapter removed. Also, I noticed that the MAC address is 00-00-00-00-00-00, with I think indicates a problem with the wireless module.
