You could give it a try - it's no skin off your back.
Sorry I just tought that it is different because I can play a half houre before disconecting, but I don't know much about connection and stuff so you are probably right.
I checked the link but it just said that I should move closer and stuff.
Sending a mail to nintendo sounds like a good idea but I will wait untill the right moment to send it (probably after my vacation because it is maybe tempirary as you said). Thank you! :D
If their are more tips or someone had this too be welcome to post :p
