Since my desktop crashed I'm only using my Macbook right now. My rock solid WDTV box would only connect and display media over a wired connection. Well this sucks because when playing any HD content it would skip because of the lower bitrate of a wireless connection. A solution had to be found if I wanted to watch good quality content on my main TV. Well here's the solution:

  1. On Mac, disable wifi.

  2. On Mac, go to system preferences, sharing, click file sharing, and options. UNCLICK your user account (be careful now anyone on your network can view everything in your public folder)

  3. On WDTV go to settings, network, and clear stored logins.

  4. Voila... you're all set.

I hope this helps someone else.
