My download speeds change from 20 mbps to under 1mbps during peak times? My Cable AttentuatIon is 0.0 dB? is this ok? i am on the silver unlimited plan... (150gb and 20mbps) and i am maybe 15 gigs into it... meaning I am nowhere near being throttled back for going ove my 150 gigs a month... I live in central California... my service has been on and off all week... I have just just one 100' piece of coax that runs from the dish to the modem.. installed by the exede instaler... the dish is mounted on a pole.. the connections to the modem are tight, clean and dry.. can anyone help me with this? the speeds at peak hours are just not acceptable? and my seevice is going on and off... ? i used to be other plans and my speeds were not bad at peak times?  What can I do? and is my cable attenuation off? shouldn't it read 1 or 2 but not zero?

It would be OK if you had a superconducting coax! It sounds like something is amiss. Here are my cable specs for your reference. I am not sure what the acceptable range of cable resistance and attenuation are, but you can compare yours to mine. I have about 140’ of RG-11 CCS.

Thanks for your reply... I kinda figured that i should have just a little attennuation... not zero? Now trying to figure out how to solve it? I am way out in the boonies... 1-1/2 hours by car from the nearest anything.. and up a steep 3 mile 4whl drive dirt road to boot... getting a service call is not easy... any thoughts on where i should start?

I am not sure how the modem is measuring the attenuation so it isn’t easy to know where to start. I am assuming you have already done the obvious such as powering the modem down and back on again.

You mentioned the modem connections being good. How about the connection to the TRIA? What does your TRIA status show? I have always thought mine was odd as it shows values for the transmit power, but the bar graph never has any indication on it. This is what mine looks like at the moment and things are working pretty well.

It does look and sound like something is off. Email viasatlistens@viast.com and, link to this thread. They can take a look and see what might be off and, work with you to decide how it can be fixed.

Even if something is off, sounds like you are experiencing normal primetime congestion.

I would check the grounding of your system also.

I wouldn't put much stock in those numbers to the pint of betting the farm on them - I've seen some pretty bizarre numbers there even cranking right along recently with an RxSNR of minus 99.9 Db. I don't think we're looking at a precision piece of plastic here, but they can be useful in determining norms - sorta like speed tests may not be accurate but give me a relative measure of where they stand against one another.

But as VSU states check for proper grounding especially a pole mount. The Viasat grounding requirements for pole mounts used to be online, but can;lt find the current ones anymore. As I recall, It used to be an 8ft ground rod at the pole mounted dish, dish grounded to that rod and that rod bonded to the electrical ground or something like that.

In my case I actually had a substandard coax ground block being used which would cause occasional problems. Wound up replacing it with an approved PerfectVision one and some sporadic problems disappeared. This one:

and eventually found someplace that  offered free shipping.

Thanks... the ground system that was put in by the Viasat installer is a ground wire that runs with the coax and one end is attachet to the dish and the other end to my breaker box.. (that in turn is grounded with a 8' ground rod maybe 6' away) and I found that the ground wire that was attached to the antenna was broken off.. I re attached it maybe 2 hours before sending you the screenshots...  I looked at the link you sent me for the other ground block... I hate to be ignorant but how do i hook this device up exactly? also here are some screenshots of recent speed test results... it feels as if i am being throttled because of exeeding my data cap? but i am way under it?

You are not being throttled.

Since repairing the ground, do you see a difference in your modem stats?

Thanks for getting back to me... I havent seen any major differences since I repaired the ground? And do you have any ideas on why my speeds are so low?

If you don't have a grounding block along the cable run that is at least similar in appearance to what is in that link you may have a grounding issue according to a Viasat Installation Grounding Job Aid dated October 2018. Hard to tell from what you've described. The separate bonded ground rod at dish appears to be only a local code requirement and is no longer really mentioned other than determining local code requirements in addition to Viasat's. The coax as well as ground attaches to it typically before entering the house; the coax then extends to the modem while the ground wire extends to the residence ground (several options are available).

While many think it's for lightning protection it's probably not going to survive a direct lightning strike - it serves a more important function in allowing built up static electricity to discharge from the cable which can damage sensitive electronic as well as affect your signal. The problem I was having - but the grounding block had deteriorated over the years due to exposure to the elements and it also appeared the old grounding block wasn't rated to 3 Ghz either. It was a slow steady signal deterioration over time, not abrupt.

But I'm no electrician nor an installer.. so take all of that with a grain of salt but a DuckDuckGo search may yield some insight as to where I found that info. We used to have a very knowledgeable dealer/installer around here who probably would have told you, but alas he's gone and not by choice - Free Andy!

In short, If the coax runs uninterrupted from the dish to modem without a grounding block prior to entry, you may have a problem...


Your speed test results do exhibit typical variance at times of congestion however; they do appear a little slow overall and during off peak hours but that me be par for the course on your particular beam. Unlimited Silver with 150 GB suggests you're on Viasat-1. When did you get that plan? Prior to February 13, 2018? Silver appears to have dropped to 60GB on that date.

Ignore the cable resistance and attenuation values.

Unless there is a red check next to it.

Your slow service is more than likely not related to those values.

If you order from a local self installing Dealer you can call them and ask for them to look in eSVT at your connectivity history for clues that would be specific to your account verses only with the beam you are on.

I have high doubts about the attenuation being an issue. As an installer. I've put in many jobs with 0 attenuation, a short enough cable run, quality connectors, approved bend radius' at all locations, no hard kinks or 90 degree bends will keep attenuation to a minimum.

Saw above someone had "140' of ccs rg11" well, that's not approved, no wonder your attenuation is through the roof.

Anyway, probably just congestion. You live in Cali, so congestion is definitely a big issue there.

Thanks Dio... I appreicate the help... My cable run is pretty short... and has almost no bends in it at all... and only 1 connector just before the modem... my download speed right now is 1.1 mbps at 9:45pm... pretty darn slow...

Any sign of that grounding block mentioned above?

As you've described it you still give me impression that the coax runs uninterrupted from TRIA to modem. Just double checking. As best I can determine, installation of a ground block on the coaxial cable prior to building entry is still required. Should look something along the lines of except with a signal wire or ground coming from the dish (antenna) to the grounding block also:

  

May not be your problem, but rule out any install issues. One of the installers who's jumped in here can help you better determine that as well as the rationale and whether its still a Viasat requirement.

FWIW, there was a pretty good discussion of the grounding requirements at:

http://www.dslreports.com/forum/r28623321-Grounding-issues-with-new-install 

a bit dated so requirements may have loosened from that but still appears to be a requirment of the United States National Electrical Code (NEC) primarily for safety purposes.

Yes, I am quite aware that the RG-11 isn’t approved cable, but it works great. And attenuation isn’t really an issue with CCS vs solid copper due to skin effect. The issue is with DC, but my DC resistance isn’t all that bad. And, everything works fine, so that is the only test that matters. If I had to trench 120’ of frozen ground to install “approved” cable, I would not be a Viasat customer.

Thanks Old Labs...You are correct... my cable runs uninterrupted from my dish to my modem... no grounding block at all... My modem is located in a small shed thaty has my soalr batteries... invertor... etc...  then it goes via etherent cable to my home... I will reach out to my installer and ask about it...

OK, can't be of much help on that one - there are undoubtedly some special considerations there that raise a number of questions.

I still think it is related to congestion.  If you are fast sometimes and slow other times, that suggest the install is not the problem.


You think 1.1Mbps is slow?!?!?!  I was pulling around 350kbps yesterday at 6:00pm.  About 8 hours later, over 4Mbps.

I agree that it is most likely due to to congestion... I was trying to rule out any other possibilities.. and I was wondering if there might be any chance that i was being put in the "your data cap is up and we are prioritizing your data behind the other customers who haven't reached their cap yet" group... my speeds are all over the board...
10am today = 1.1mbps...
9pm last night - 1.1mbps
7am yesterday 30.4mbps!!!
9pm Thursday = 0.9mbps
9pm thursday = 0.7mbps

On a side note is there any way to fine tune the antenna myself? I used to be able to acess my router and then put in my beam key code... Then the tria would start to beep and I could very carefuly adjust the antenna to get the best tone... but now the modem doesn't accept the command?

Your RxSNR looks good. If an alignment issue, it wouldn't. Regardless, you shouldn't mess with the dish pointing at all. In fact, the installer can get in big trouble for giving you that code.
I get that you live in some remote region in the middle of nowhere, so it is hard to get support onsite I am sure.

Your speeds are over the place, and there is no consistency to it.

As long as you are not over your priority data, no restrictions are placed on your account. All part of the magic and mystery of satellite internet.

gotcha... It would be nice to figure it out... I used to have much faster speeds that were consintent... It seems to have changed about 7 or 8 months ago? And I upgraded my plan to the unlimited data plan a year ago...

Are you on Viasat-1 or 2? When you upgraded did they change modem and repoint dish?

No.. They just mailed me the new modem and I replaced it it myself... does that mean that I am on Viasat 1? and if so is #2 better? and do you know if #2 provides coverage for my area? central coastal California...

Two different satellites. Viasat-2 is the newer one.

Go to the Viasat website and plug in your address. If you see plans of 50 or 100Mbps, that is Viasat-2 and available in your area.

Looks like congestion to me. 9-10 PM Prime Time and, a Sunday morning when most people would be awake and, not working, thus, online. With early morning weekdays being fast and, prime time and weekends slow, that's congestion.

 the congestion is a little sad only because those are the times that I am also free to acess the net... and the congestion is something new... in the past my connection never dropped that slow.. even during the prime times..

Looks like I might have found the culprit? I am on grandfathered in on the silver unlimited plan... I was promised speeds up to 25mbps and 150 gigs of data ... after I hit my data cap then I would be prioritized behinded other customers during “peak” hours... that was the plan I signed up for. and paid for.. but it seems they have changed the rules of my plan after I signed up for it.. now my speeds are prioritized behind other customers at  “Peak”  times even before I have reached my data cap?because I purchased my plan before February 13th 2018... I am shocked that they can do this to me? If you make deal then stick with it... it seems unfair to change the rules after the fact? Am i allowed to change the rules after the fact? Does anyone know if we have any recourse about this? I have attached a Viasat document... that btw I was never sent.. I found it online...

It all depends on what your original contract says. Many contracts say that the terms may be changed at any time in the future. Often notice is required, but if notification isn’t required by your contract, then they can in fact do what they did legally. It all comes down to what the contract said at the time you signed it. If the contract didn’t allow changes to be made unilaterally, then I think you have a legitimate beef and I could contact your state Attorney General, unless you are independently wealthy in which case just hire a lawyer.

I am talking legal here, not what is or isn’t a good business practice. That is another discussion entirely.
