Have you tried reinstalling the Samantha firmware? I don't know if the Samantha module ships with the latest firmware, so that could be an issue as well. That's the next thing I'd try if I had an issue like that.

Are you running security on your router? It's possible that the security settings were put in incorrectly in the Samantha wireless config utility (that sets up your USB drive to be used on the Samantha). If so, you could double check that and/or disable the security on the router to simplify things. (and run the wireless config again + update the samantha again).
