Have you checked into the "type" of loss you are having ?
Is it upload or download ?
Legacy plans did not count download against your allowance, Gen4 does.
Routers have vulnerabilities ....
Is the "front end" of your router protected by a username and password different from the routers default values ?
What level of encryption, if any, do you have setup on the wireless portion of the router ?
Did you enable "remote access" to your router when you set it up ? If so disable it.
Did you ensure the WPS function of the router has been disabled ?
Do you really know at any given moment just what devices are connected to the wireless portion ?
To that end perhaps you should install Wireless Net Watcher so as to make it easier:
As to buying a new router .... I think you may be a little premature.
Process of elimination applies:
#1: connect a single computer directly:
If the loss stops, its not THAT computer
If the loss continues, it something on THAT computer and there IS software to track what is being used by what program or process.
#2: Repeat that process, one computer at a time until all wired computers are "cleared"
#3: When all computers are "clean" connect all WIRED computers to the router, connect the router to the Modem ..... BUT DISABLE THE ROUTERS WIRELESS FUNCTION.
This will allow the router and its firmware to operate but will 100% guaranty that no wireless devices are installed.
Process of elimination.
I really am sorry I troubled you.
You have made repeated posts indicating your frustration.
Every problem has a root cause. I may take some detective work to find that cause but keeping an open mind and Divide & Conquer approach works.
I also have Hughesnet and every time I have lost data, it was on my end .... other than that, no problems.
The same algorithms that Hughes uses to count my data is the same as yours.
A single computer has 65,536 comm ports. To that you can add multiple computers and a plethora of mobile devices.
You appear to have made up your mind that the loss has to be on the Hughes despite the preponderance of evidence.
Its a pity you are above accepting help for your problem ... there really are some knowledgeable people in this Community.
