The model is an LN32C550, and you're using the television's media to control the content? Is that correct?
I have an LC32550 TV and the samsung Dongle (WIS09ABGN. I have a 1 GB connection and a linksys router. I have samsung PC share manager but while I am able to connect, the WIFI disconnects while transferring the files. Once the files are transferred, only then I can connect to the Media Player and view the photos. Is this normal? Thanks
