One thing I recall, Prior to Sunday, all as working fine. When we got up, it was obvious there was a power interruption overnight. That morning is the first I had the linking problem. This morning I disconneted all power to the hopper and 2 joeys. Then I powered up the hopper. Then one joey and once it was up, the other. Since doing this yesterday to the hopper and one joey, and those two were fine, since I did this, this morning they'e been fine. Still l have S234 on the hopper and S282 on the joeys. Hope to get the new hopper sw as I will be receiving the OTA module today, which has a blank screen fix in S237.
