Does anyone know why the Hopper 3 w Sling would be periodically Automatically Reboot? The Dish Contact has replaced the box, had a Dish Tech here, had me remove the EHD and had me tighten all connections but the Hopper 3 with Sling Reboots periodically such as early morning, watching a live event or a recorded show, late afternoon with sometimes as many as seven reboots in a row! Happened in last 3-4 weeks-never had any problem before! I've given up and ready to throw whole thing out the window (Hopper 3 and 3 Joeys) as it is not RELIABLE!!
