Automatic Reboot

Every Thursday night at 7:00pm cst our Tablo reboots. We are trying to record Grey’s Anatomy at 7:00 and it gets recorded 4 times for a minute in each recording. I have read in other posts that weak signal can cause a reboot, but the show right after Greys Anatomy, Station 19 records just fine. Does anybody know if there is a setting or something that makes the Tablo updte and reboot at the same time every week? Because every other show we try to record is fine.

Could you be conflicting with another recording at the same time?
