Pokemon Diamond can't connect to My Pokemon Ranch?

When I try to connect my DS and my Wii, the screens on the DS stay white right after I select "Connect to Wii".
Anyone know a solution for this problem?
I'm using a M3 Real with the latest firmware.

Probably not compatible with going wifi on it.

So is the M3 completely incompatible or do I just have to wait for a better firmware?

Most likely wait for new firmware. Try going online or wifi with another Wii game or DS game if possible.

Okay, I don't have any problems going online with other games, so I'll just wait.

I read somewhere before that flashcarts aren't compatible with the wii, well it was a year ago so who knows :P

Only those flashcarts which have trouble even doing wifi with most games with another DS or online via router or connector.
