# weeks ago, my TRIA and dish were also replaced, so it's basically a new system now. What would cause the cable resistance to keep climbing like that?

Bev, did the installer apply dielectric grease to all outdoor connectors and then properly weather seal the connection?
Moisture can condense in the "void" within the connector that will lead to issues.

That is going to be a recurring thing at certain times of the year here. Also good to know if it happens to others in similar climates.
NOTE TO OTHERS: Be very careful doing what I did, if unsure of yourself, call for a service call and, let a technician do it. I build my own computers, among other electronics hobbies, so I'm fine doing little things like that and, know to be careful not to bend or break anything and, make sure it's 100% dry before reconnecting it.

The room the modem is in is also open to the kitchen and, canning and, general cooking adds steam to the air on top of the ambient humidity. Not surprising to me, with the temperature changes and, high humidity, condensation happens.
Windows have been fogged up every evening from about 9PM until about 8 AM every day since Harvey made landfall. Without a storm making it this damp and, creating such a large temperature change every night, it wouldn't happen. If I had central air, or ran dehumidifiers it wouldn't happen. May not happen if I didn't can or boil as much food in the kitchen, or if the modem were more isolated form the kitchen either.

Folks, when you go to most web pages these days there are often 30-50 things loading in the background that YOU never see going on but they will bog a wimpy processor down to a crawl....even with a good Intel processor it can still take 20-40 seconds for a page to finally "settle down". His advice to me was to buy a laptop with an Intel I5 or I7 chip. I promptly bought an HP Elite book with an I5 and it runs like a scalded dog compared to my old laptop that had the AMD chip.
Same thing goes for those cheap tablets you see in the big box stores. There's a REASON that the Samsung or Apple tablets cost so much more than those RCA ones. And don't EVEN get me started on the built-in streaming software that comes with most TVs and Bluray players...they are a connectivity nightmare.

Some days I just want to beat him over the head with his devices - one thump for every open app that should not be left open. LOL

I respect installers that take the time to test every possible cause of a problem, or diagnose a system thoroughly when doing a service change. The one that fixed mine replace the coax, replaced the TRIA, replaced the modem, even replaced the dish itself in the process of trying to get me the best possible service. He was determined to get that SNR at 9 or better - ended up at 7.2 with nothing more that could be done. Just the area I live in. Even DirecTv can't get above 80 on any transponder.
You sound like that kind of installer - the kind Viasat needs to find more of. :)

Bev, It probably has nothing with your issue but in my Exede Installer training we were told that there should always be a MINUMUM of 40 ft of coax from TRIA to Modem because some attenuation is desirable.I can confirm, using my installation as an example, that there definitely needs to be at least 40 ft of cable and at least one ohm of cable resistance between the modem and the tria. If you don't have that attenuation, then voltages, large enough to potentially wipe out both the modem and the tria, will build up in the circuit between the modem and the tria due to electronic resonance.
When my service was first installed, the cable between the modem and the tria was only 10 ft. It wasn't long before the service started intermittently cutting out for a few minutes at a time every so often. Then, about a month after the service was first installed, the service cut out for about 22 hours and, when I looked at the modem status page, it said that there was a problem with the IFL. I then had a service call done where the 10 ft cable was replaced with a 40 ft cable between the modem and the tria, and there hasn't been a problem with the IFL since.

Your installer probably used your existing coax......I've done the same...only problem is that now it is causing a problem. He might have to run a dedicated line.

Take a look at the printing on your cable jacket. You should see either a "CC" or "SC" printed on it. "SC" is for "solid copper." Solid copper is required and your installer should not have used existing cable unless it was solid copper.

That's my first thought as well. Look at the connections, unscrew them and see if there's moisture inside.

On the big coax. I put on a layer of 130C then a layer of Scotch Super 33 insulating tape, then a layer of coax seal and then a final layer of Scotch Super 33. I make sure that I lay the tape from the bottom upwards, like the shingles on a roof, so that the joints are facing downwards. Nothing is going to get into the coax then. Always cut the tape with a pair of scissors don't pull it to break it.
I use adhesive heat shrink on the coax end of PL259 connectors.
