Ok, finally got my hands on a WDTV Media Player *New Model* (not the SMP)
Now, contrary to what i said about having the ethernet cable in at the same time you’re using “miracast” which is Wi-Fi…
You can have the ethernet cable plugged in and miracast will still work… i’m guessing, it switches to wireless mode when using miracast and then when finished… reverts back to wired connection.
When my Wi-Fi signal is weak (on either the Tablet or WDTV) … then the miracast handshake doesen’t work.
So, here’s a pic of it working with my Pipo M9 tablet
