Okay, now it won't work again.
I've spent who knows how long trying to make it work today and it just doesn't allow me to clone anymore.
The only other two ways won't work, either (my neighbors apparently have devices that search for internet, causing my WLAN light to blink even when not in use...I don't know how to do it with trading other than GTS). Is there a fourth way that I don't know about? Or am I doing something wrong?
