What you are seeing is pretty typical of a 3100 that has receive lock and is trying to establish NOC communications. Failure can be due to
1. Inadequate transmit power 2. Too much transmit power 3. Anything else out-of-spec that the NOC sees, and won't let you into the network.
In most cases you need to work with the provider. For 1 or 2 they would typically push a new options file with different initial power settings - for 3 there would probably have to be some back-and-forth with a network engineer.
Since initial power requirements vary for different locations there is not a one-size-fits-all. For mobile users (particularly Ethersat) I have a utility that will slowly ramp power up if needed. Fixed users should determine what their power needs are and get the options file written accordingly. -- Motosat self-pointing dishes: 1.2-meter XF-3 on 105W or 121W, .74 meter G74 on 89W, SL-5 HD DirecTV|idirect 3100|Hughes HN7000S|Verizon UMW190 Air Card|1990 Blue Bird Wanderlodge Bus "Blue Thunder"|Author of hnFAP-Alert, PC-OPI and DSSatTool
