Starband in Louisiana

Hello,
Im in north Louisiana and unfortunately stuck with Starband. I have a Skyedge IP vsat modem and im suppose to be getting 500 or so down and 100 up. I've only had this system since January 07 and its been problematic from day one. Tech support doesnt like talking to me anymore, apparently they dont like being criticized for not knowing whats going on with my connection. Heres the deal, over the last 2 weeks my connection has been getting slower and slower. 3 days ago i ran a bandwidth test on speedtest.net and hit 16kbps down and 22up. You can imagine how upsetting this can be when your paying 50 bucks a month for 500 down. Just for self assurance, i ran the test 4-5 times, each to a different server which generated close to the same results. It was to late in the day to contact tech support so i surrendered for the night. The following day i was running around 200-220 down and 60-70 up which is also what im getting today. So far i havent been able to get starband on the phone nor a response from email. I should also add this is with clear weather.

My system is clean, my pc knowledge is extensive, i build, repair, upgrade, clean, etc. My knowledge of satellite internet simply sucks. Im behind a router with 2 other machines on the network however they were unpluged during the bandwidth test. My EbNO runs 6-6.5.

I doubt that it matters but i have access to the installer side of my modem, modulation and coding setting etc. but dont know if theres a benefit to it.

Is there anything i can do to at least get up to where i should be? Are there any adjustments that can be made on my end that would help?

heres a test result from 4/24


heres one i just ran


I don't have anything running in the background

Do you guys have any ideas at all?

Thank you for your reply

Rebooting the modem has no effect
Off peak hours has been hitting 250-300 down
Starband tech tells me my ebNO is normal, they checked my alignment and called it good. To me, it looks as though the signal could be better but i dont know. Heres a screenshot from my modem.



A means to determine transmitter isolation is beyond me. I'm not real sure what exactly that is, my apologies.

A light rain will knock me offline pretty quick, usually i have to go out and wipe off the horn to get back on after a rain.

Starbands equipment is in Atlanta Georgia so thats where im running my speed test to.

From forum admin: I have moved the image file in the above posting. Any query please email eric@satsig.net

Their policy is the installer is responsible for 3 months, after that your on your own. None the less, their trying to convince me that i have a good signal anyway. I can also tell you when my signal drops below 5, my actual internet speeds are worse than dial up. I dont see how 6 could be good if 4.9 is pretty much useless.

Check all is tight, then repeat the Eb/No measurement several times.

With a low receive quality Eb/No =5.96 dB I would start with 1/2 a turn up on the elevation nut and look for any change. If an improvement, keep going, otherwise try the other way. Then optimise azimuth.

Best regards, Eric.

Pay particular attention to anything mentioned about transmitter isolation. Eb/No is important, but it's a function of your receive. You can achieve good Eb/No, but still have bad transmitter isolation. Once the best Eb/No is obtained, you must then move on to optimizing the transmitter isolation. It's counter-intuitive, but it's then normal to peak transmitter isolation at the expense of some Eb/No

That is the specific reason that I first mentioned obtaining the services of a Starband installer.

i might be able to explain "hang" a little better

It will start downloading/measuring, pause for a sec, resume, pause and so on. It does this on both down and up test. I hope that makes a little sense.

i didnt mess with it.

I don't see any mention of your scew angle. Scew angle can affect your Transmit / Recieve signals. I have set up the dishes consistently with signal quality of 9.0 and higher.

Moderator Edit: I believe the poster means "skew" angle, otherwise referred to as POL or tilt angle//greg//

Admin Addition: The figure below shows an example only. ??This system is set to receive nominally horizontal polarisation with a minus 13 deg anticlockwise adjustment applied. The satellite is a little to the left of due south (for northern hemisphere locations). The polarisation starting position (before the adjustment is applied) is with the broad faces of the LNB waveguide and filter exactly on either side - this is true receive horizontal polarisation.

Find your polarisation adjustment angle here:
https://www.satsig.net/maps/satellite-tv-dish-pointing-usa.htm
A good way to set it is to put an inclinometer sideways across the BUC, LNB body, LNB waveguide narrow edge etc. You may even be able to read a tiny scale on the feed throat.
Note that adjustments are made while facing the satellite.

Always start by setting either horizontal or vertical, as instructed by the hub for your downlink signal. Vertical is with the broad faces of the LNB waveguide on the top and underneath.

Best regards, Eric.

Here is a diagram showing a minus - 45 deg polarisation adjustment (IN RED) being applied.



If you are already receiving a fairly good signal then it is probably a case of you getting a clear understanding of where the minus - 28.2 deg adjustment needs to be applied and then making some small movement if necessary. 

Note all four alternative starting positions. 2 for horizontal and 2 for vertical polarisation. The choice of the alternative starting positions is needed in some configurations to avoid parts hitting the metal arm or yoke bracket. Otherwise the adjustment movement required may appear impossible.

Perhaps if you send a picture (to eric@satsig.net) it would help. Put the camera at the top of the dish facing towards the feed.

Best regards, Eric.

?Eric,

i apologize for not getting some pics sent yet, i've been working like crazy. I did run into an interesting situation though, im the proud owner of a craped out router. I disconnected my router and ran straight to my pc and it seems im getting all (or the majority of) my bandwidth.


I guess thats what i get for buying linksys. I would still like to send a couple pics if thats ok, thats assuming i'll be off work early enough one day to snap something remotely close to visable.

OOPS,

  Sorry, I just registered on this site today and saw the previous conversation.  I am a Starband dealer/installer in Louisiana and do vsat work on lots of other systems.

  If you take the Starband online installer certification test you will be able to use your cert number to align the system using CVACS, their direct telephone interface to the hub and get precise co pol, cross pol and adjacent satellite interference.  This system is available 24/7/365, no operator assistance necessary.

Well guys,
Despite all the available help i've ditched starband all together. After 6 months of nothing but headache i just couldnt take it anymore. My router has been the least of my problems. I've had an installer out twice and a modem replacement and still no signal. Personally i suspect a faulty LNB but im at a point that i could care less whats wrong with it now. Its been down for 2 weeks now and all starband can do is scratch their heads and wonder whats wrong. I've made a few phone calls and located a wi-fi hotspot 3 miles from me and guarantees he can reach me from there. Im in the process of constructing a tower to clear a couple trees and i should then be internet bound. I should be running 1 to 1.5 MB down and 256 up with cable/dsl latency for the same cost i was paying starband. $200 setup as opposed to starbands $500 setup.

Starband is trying to charge me $500 for early termination for a service that they couldnt provide. I've given them 6 months to correct everything and at least provide me with a decent connection and they cant seem to do so. Their conclusion is that something at my location is causing an interference with the signal, although theres nothing in front of the dish but open sky. If theres an RF interference i would have no idea where it would be coming from nor do i feel its anything under my control. In my opinion thats something the installer should have determined and corrected if possible. Im not sure if the EMF signal from power lines would be a factor but again, thats the installers call.

Thanks to everyone who offered advise on my situation, its people like you who help make the world go around. If anyone is ever in need of PC support, drop by (web site pctechforums.com no longer working) and perhaps i can return the favor. Im a Mod over there along with several other great people.

Thanks again,
