What model? You have to have a Network router of some kind. An expensive NAs can do the job...but can something cheap do it? Without the model number we have no idea. If you not going to get an expensive NAS,,,then a router with a USB socket which can become a cheap NAS is a better option.
I have a Mede8er 500x, The Link Station I've been offered is a LS-W2.0TB GL/R1-EU
I'm using a WNDR3700 router, I can only stream using this router connected via RJ45 cable to the LS, I would really prefer to be hard wired direct from the LS to Mede8er unit
