OK - here is what I have:
Acekard2i
DSI and a DS Lite
NDS Backup Tool (Wifi) v0.31
I edit the ini file to point to my laptop which has smallftpd running. Both the .ini and the .nds files for the backup tool are in the root directory of my SD card.
I tested smallftpd and was able to transfer a file from my desktop PC, so I think it is configured correctly
When I run the backup tool from either the DS Lite or the DSi, it sits there with the "Connecting for Access Point . ." message. smallftpd doesn't indicate that there is a connection established to it.
I shut down my internet security on my laptop and even directed the DMZ on my router to send all incoming requests to my notebook. None of this helped. I also tried using both the local IP address and the external IP address, but that didn't make a difference.
Any suggestions?
