I recently had to go back to useing my USB connector because my wireless router went down. I've used it before and know it works but i'm not getting the error code everytime that means that a firewall or something is in the way (i checked on nintendo site) but even if i disable my firewall (which i'd like not to do) it just comes up with the same thing

anybody know what to do abou this? plus i heard you can tell your firewall to allow certain things through, would tht solve it and if so how do you do it?

the error code is 52203 but i did explain wot that is in the question if you look
