The only ways around the WPA problem is to lower your security in your router, I suggest at least 128 bit encryption as this is the highest the DS can handle. The second option is to get a USB dongle for your PC. This way the wireless signal goes via the dongle and through your PC and onto the net so it does not matter what settings are on your router. The only thing with using the dongle is that you may see two access points when you do a search on your DS and you need to make sure you choose the dongle and not the access point.
