I hope someone here can help with a very strange problem and save me from lighting a HughesNet bonfire in my backyard... Sorry for the length of the this post, but I am trying to be as detailed as I can. If I missed something important, or something is still not clear, please just ask!
A little over three weeks ago we had an HN9000 with a wall mounted .98m dish installed. Since installed, the modem regularly reboots itself (say between 7 and 90 minutes) and occasionally locks up such that it requires the power cord pulled. About 5% of the time that it is up, we have troubles accessing web pages (and get the web acceleration problem page "Web Acceleration Client Error (504) - Suspected Satellite Link Outage") but email, ssh etc works fine. I suspect that is simply a symptom of the reboots but can't be sure. The reboots are like a complete power cycle, and we initially even loose access to the modem status pages.
We have already had a repair technician come out twice. The first time, he suspected the wrong power supply and when he arrived it was supposedly the wrong power supply and replaced it with a higher capacity 73w YM-2071A and left. No change. The second time he had to realign the dish (strong winds here had pulled the upwind arm loose) and then replaced the modem, power supply, and parts of the tria/lnb/whatever you call it with this system. No change.
I say parts of the tria, because I saw the repair tech pull the funnel shaped part out from the old and insert it into the new one. When he came back in and powered it up, he mumbled something, powered it down and went back out and was back up on the ladder. I'm not so sure he didn't put the old one back up, but I don't think so. It took longer than reattaching a cable, but less time that it took him initially to swap the tria.
I mention the specifics on the tria, because he told me that "they" (Hughes) wanted the dish and cable replaced but he saw no need to do that, and even told the Hughes guy on the phone that he replaced everything. Maybe "everything" is understood to mean everything with a chip/resistor, I don't know. I find it odd he replaced the power cable and mentioned how that could be the cause, but said that the coax tested fine and no way that could be the problem...
The install was done with no grounding, in fact the original installer clipped the ground leads such that there is no way to attach it without cutting and putting new ends on the coax. He also took pictures of an unrelated pole in the ground and submitted that as "proof" of grounding. The repair tech tried to sell me that having it grounded was actually dangerous and caused serious injury to an old lady who was sitting near her equipment in a lightening storm. I didn't bother to refute any of that nor explain the purpose of the ground. I did run a 10ga ground wire up to the dish and attach it to the tria after he left, but the problem still remains.
Since he left, the dish came loose 3 more times and the final time I drilled and screwed the adjustable arm. Luckily he had realigned it with the arms fully compressed so I was able to find "home" again. It might be a a tad off (188 receive signal strength, 37 normalized power word) but it behaves the same as it always had.
So that leaves the one odd part out of our specific installation. We are on a generator (nearest power line is miles, and $250k away. Nearest neighbor is 9 miles away. Nearest tree is a lone tree 2 miles away 🙂 and that was the repair tech's bosses only suggestion. He suggested that the modem was very power sensitive, and it should be on a UPS.
So... I have a Tripp-Lite UPS which I have plugged the satellite in. No change. I unplugged the UPS from the wall and ran it on battery. No change. I have a much larger generator for welding etc and wired into that. No change. Prior to this, we have been here 7 years on WildBlue (and then almost a year on Exede) and never had a problem like this. I can believe that the UPS would not be ideal as it is not a pure sine wave source (since it doesn't really matter for switching power supplies), but the generators are. I even ran some heavy cycling equipment (toaster, freezer, etc) that cause the smaller generator to have to power up to supply the house electricity and _that_ never caused the satellite to reboot. I would expect that if the modem is that power sensitive that would cause a reboot but it does not.
Any suggestions? I would like to get some fresh ideas. I hate to call and schedule another appointment without something new. You know that definition of repeating the same thing and expecting different results...
