I use a nintendo dsi with 1.4U and with an Acekard 2i on the latest firmware. I used to be able to play all the games with no problems, but recently my internet dropped dead and came back, though thats when i started gettin my error. When I try to connect to wi-fi in ANY game, homebrew too, I get the error 51300. HOWEVER, Advance Warz 2 days of ruin works perfectly, and the internet channel and hatena and the dsi shop work. I tried usin the customer support on nintendos webpage, but my router wasnt listed. I have a Westell UltraSeries 9100EM. Can someone help plz? I'm gettin desperate not being able to play EDIT: crap didnt realize how misleading the title is, how do you change it?
