First, the Dish Network receiver. Even though you don't actively do anything with it, connected satellite TV receivers can still use data, and a considerable amount. It wouldn't at all be surprising if this is where at least some of your HughesNet data is going. It's best to sever that connection to ensure that no data is used. This is also a reason why HughesNet recommends against connecting satellite TV receivers to HughesNet's service.
You may also want to take a look at your wireless printer and make sure that it's not connecting to its home site on a regular basis, as this can use data, as well.
It definitely sounds like you have something that is using your data without you knowing, as is evidenced by the 2GB of token data being gone by the next day, even though it sounds like you weren't doing anything that should have used it. In addition to the two things I've mentioned (sat TV receiver and wireless printer), this post and this post may help with the data usage issue. Additionally, the reps may be able to see what device it is that is using the most data, though I'm not sure if a Gen4 modem allows them to see such.
---------------------------------------
Regarding the WiFi calling, even if the speed improves it still may not work. Officially, HughesNet does not support it, so other than trying to improve your speed for the sake of the speed, they most likely won't do anything to try to get your WiFi calling to work. HughesNet does offer their own Voice service, though. Edit: I see from your prior posts that you may already have HughesNet's Voice Service.
---------------------------------------
Regarding your speed issues, the HughesNet reps will need some speed tests to be run at testmy.net, and using a specific protocol, which I'll post below. When you run the tests, please be sure to be using a single device that is directly connected to the HughesNet modem with a LAN cable, and to run them while signed into a testmy.net account that you create (or have created already). No 3rd party router or WiFi can be used during the testing, as they can affect your speed. Just a direct LAN cable connection to the HughesNet modem. And, with you having Gen4, you likely have the HT1000 or HT1100 modem, which has no internal WiFi to disable (just in case you see the instruction to do so elsewhere). The speed testing protocol is as follows...
To help the HughesNet Customer Service Reps get a head start on your speed concerns, please create a testmy.net account (if you do not already have one) and, while signed into that account, perform a batch of 3-5 tests during different parts of the day, then share the account results link with us here.
Most important points to remember during this test:
-do the tests while directly connected to the HughesNet modem with a LAN cable (NO third party Router or Wireless devices can be used)
-use the 12MB size download test file
-If testing upload instead of download, you must use a 4MB size upload test file
-space each test at least 5 minutes apart
-post your testmy results URL here, it may look something like http://testmy.net/quickstats/yourusername
For a more in depth guide on running the tests, please see this site .
The Reps are on M-F from approximately 8AM to 5PM Eastern. They will be the ones to address your speed issues, but they will need these tests to do so.
We're closing this thread since we never got a reply from you. If you still have concerns, please start a new thread and include a detailed explanation along with the speed test results GabeU posted instructions on, so that we can more effectively help you.
