I found that with NDS backup tool in order to connect to my access point I had to do the following.

Change Security to WEP as it was originally trying to use WPA (which was just not going to work).

Change my Wi-Fi channel to '6' , it was originally on '11' and it would not connect.

You also may want to create a WiFi connection from the Internet Settings menu before using the tool.

Give this a try and let me know.
