Mini box issues

Just installed a new wireless mini box and have had issues from the beginning. After programming it and the remote and programming the remote to the tv the box decided to just not work at all. When i turned off the power to test the remote and turned it back on all I got was no connection. I had to walk around the house and turn off other boxes and reset my gateways and still nothing then I turned it off and on again and it worked. Now every time I power on the "all power" button I get the same message. No signal or no input. I notice that the box does not turn off even with all power button Only the tv turns off. I have now had to reboot all of my boxes multiple times for no reason. I just checked the box again and all I have is no connection. When it works its completely random.
