Need some help with Phantasy Star 0 Wi-Fi...?

Hey guys!

I'm using the Bahamut US version of the game and playing it on my DS lite with an Upgrade Revolution for DS.

Single player works fine to my knowledge but whenever I try to connect to my router at home it gives me the 51300 error code and says it cant connect.

I know its a software issue of some sort because my DS detects my router as an unsecure network when its searching for new networks.

Does anyone have this problem?

Does anyone know of a way I can get this multi-player working?

Thanks!
