Stealthboy put it this way. This wireless router is so old that WPA wasn't even invented when we purchased it.
Thanks Alec. I think that's all there really is left to do for me. I've tryed to share my internet connection with my Airport card with no encrytion or filtering. I've tried to create a dedicated network just between my computer and the DS. I've tried to make the DS connect directly to the airport. I've had it automatically assign itslef an ip via DHCP and I've tried manuall. No matter what happens, it wont work. And it seems like a get a different error everytime, even if my configuration is the same.
