UHD/HD over wifi connection to main 360 TV box? wow! that means i need a strong wifi signal for that to work.
Do most of you run cables everywhere from 360 TV box to Mini box??
You don't need to run any cables between the360 main box and the mini, both boxes will have their own separate coax feeds for live TV, you really need to connect the main box to the hub using ethernet cable the mini box can be connected to the hub using ethernet cable or wifi, my mini box works fine using wifi but it may depend on the location you put your mini box.
The mini box can set recordings on the main box and you can watch them on the mini box, you will need to set the main box to fast start or active start so the mini box can talk to the main box when it is standby.
