This was my original post:

I have finally solved this! The way to get DS Hobro, and any other ds wifi app you can't get to connect to the wireless network to work, is this:

You need to make sure that you wireless router is broadcasting the ip address, yes, this can be a security risk, so enable Mac Address filtering. This way, the DS can see your network. It has to do with the homebrew wireless library, I think, but if you are broadcasting your ssid, it works.

Enjoy! and I hope I helped some of you guys out there.
