Your plan specifies your Download speeds of up to 10Mbps. Your Testmy results show that you are getting 23.5Mbps and as much as 31.2Mbps. These numbers are both in bits per second, not bytes. So your download speeds are MUCH better than what you purchased.
Your upload speeds could be better, but not untypical. 516Kbps (up to 1.2Mbps) versus as high as 2Mbps.
I suspect that something else is going on (and it did for me in the beginning). What are your Latency numbers like? About the best it will get with any satellite is 650ms, whereas cable is around 50ms, and sometimes as good as 10ms. This is why cable performance is usually much more snappy than Satellite. My DSL is 10 down, 1 up, and it generally feels much better than my satellite 20 down, 2 up. I keep both ISPs because two or three day outages with the DSL are not uncommon, and I have a way of quickly switching back and forth. Depending upon what you are doing, the latency can really kill you, and there is nothing to be done about that darn slow speed of light.
I suggest you try the free program WinMtr.exe. This showed me that many of the hops from my home to the destination were timing out, although it didn't tell me why. After quite a bit of testing over several weeks, I found that if I slowed the Ethernet speed from my desktop to the Hughes modem from 1 Gbps to 100 Mbps that my throughput increased by many times.
I found that if I slowed the Ethernet speed from my desktop to the Hughes modem from 1 Gbps to 100 Mbps that my throughput increased by many times.This is really good advice, and I think this has been mentioned elsewhere in these Forums. See if you can't change your LAN card hardware settings to take it off Auto and lock it onto 100 Mbps.
But, how does one slow the Ethernet speed from the desktop to the modem?Process is similar in Windows 7. You need to get into your LAN Adapter settings.
Of course there are no guarantees. Your ping times were very slow. Usually around 750ms.
In my case, it appeared that 1Gbps was causing the modem to fault, and cause some kind of "reset".
There is a "test" in the Hughes myAccount called the Web Response Test. I was getting numbers as great as 70 seconds, whereas less than 1 second is normal.
I have had Auto Negotiate choose 1Gbps which would then not work reliably.
Your problem "might" be in the latency. Some internet applications (e.g, email and banking) involve a lot of back and forth communication with only small packets of information as part of the data stream. Hence even with high bit rates, the effective transfer becomes very slow because of the latency with each back and forth. And your latency is abnormally high.
In my case, the problem was lost packets, and WinMtr helped show this including the first jump from the computer to the Hughes modem (about 35 feet away) which I was able to address with better cable and slower speeds.
There may be another program like WinMtr that automates the measurement of ping times which might show something like where it is happening. Whether you or Hughes can address this is another matter, but trying to find what "it is and is not" is important in future conversations.
Maybe one of the others can answer this: the basic OS ping includes four tries. Is the result the "average" of the four, and would lost packets cause large latency measurements?
