Misc error code 85020 brawl

[oliebol]

Hi,

I wanted to play brawl online. I was making contact with the wifi usb connector. But when I wanted to play a match it suddenly said this: Disconnected from network during data transmision. It's kinda suckish cause im getting this over and over again. Maybe you know how I can solve this?

EDIT: I just tried the wifi on mario kart and it worked there. So I think that brawl is the problem. I also got 84020 and 80010.
