Because my router's pretty old and only supports WPA and not WPA2, for a bit of additional security I like to use MAC filtering and I don't broadcast my SSID. With the 3DS I can enter the SSID myself using manual set-up, but I can't connect unless I'm broadcasting the SSID, ie I can't work out how to connect to hidden networks like I was able to on my DSi. Has anyone worked out how to do this?
