Apologies for raising this thread but having more issues again. Since Thursday, I've noticed that the upstream power has risen from 47dBmv to 54dBmv. I also noticed that one of the downstream channels wasn't locked on Friday night. A quick reboot sorted that but I've had a look again this morning and once again, the same downstream channel is not locked. So ignoring the Post RS errors, anyone care to speculate what could be causing the two issues? I know I could have a technician out to move the coax on the tap point, to bring the upstream down, but surely that's just masking whatever the problem is? They did that before.
