Have you shared the files on your puter, if not, wont work
I have mine wired to the router, then wireless to the wdlive, you'll have to upgrade your router if you plan on streaming hd movies though, i have a netgear wndr 4500 and it barely gets the job done, i'll run a ethernet cable to the wd if it buffers too much. If you have shared your files, you can manually access the files thru the sort & filter content menu, select content source, then network share. hope this helps
