The firmwares avalible to download here have no relation with your software. This is a help forum concerning other aspect of the hardware. I think this media server is incredibly bold to link here as a support forum for their product on WL-HDD.
I'm going to try this product, so I'll tell you more about this later. Most of the firmwares available here are giving you more options, but there will not be any how to for your request, only people like you willing to help.
