Been playing mario kart online for a week now, its been a good experience for the most part. It was really simpe to set up with no fuss. I'm not sure why sometimes the yellow light flashes indicating a person has been found but sometimes it will make a beep and stop, then I'll have to wait for another person, so I'm slightly concerned about that. But yesturday I tried to connect to somebody on my friends list and the blue friend icon was flashing indicating a friend was online but it wouldn't connect to them even tho we were both online. At about 4am I had messed with aload of settings and restored my routers defaults and reset the DS wifi settings and it finally connected us. :P I just hope it stays working.
