You also said you have Windows 7 and have your updates set to go at 0300.
On some W-7 units, depending on the "Power Plan" chosen or set up by the OEM,
you can have your check for updates set to check at 0300 but it either does not wake up or checks but doesn't do the actual download until you physically wake up the computer in the morning.
You can click on the Start button and type "Power" in the search box. It will take you to the Power Plan settings, and you will find many different plans plus modifications to the plans.
Do you ever notice a little icon in the taskbar that says updating if you hover your mouse over it?
If you click Start/All Programs and scroll to the bottom you will see the symbol and can click on the Windows update button to manually check for updates, as well as see when the last update was checked/ downloaded.
Are you on a daily or monthly allotment?
How many MB does the 2% you mention amount too.
As William said, you are going to have to isolate to one device at a time for a period of time to determine that the problem is not on your end.
Have you tried unplugging your modem and your router for about 30 minutes; then plugging in the modem and letting the lights stabilize for about 5 minutes before you plug the router in. Let it stabilize a few minutes before you bring your computer out of sleep.
Could you, Gwalk and Sgoshe give us a simple explanation of the cause and effects of data looping?
At times the modem will get the command to update its firmware.
Sometimes ... rarely, but it happens, the loading of that firmware will fail, the modem will reboot and go to its "fall back" firmware, and then try to update again, in an endless loop.
That is one scenario ....
It can be proven/disproven by disconnecting the LAN cable from the back of the Hughes modem for a period of time (keep a paper log) and doing "before/after" after screenshots of the most accurate of the usage meters ..... this one:
It can be found here (after logging in):
Does the firmware update or the failure to update and looping get charged to the customer's data allowance?
Is the modem automatically rebooted each day at 2 AM and 7 AM?
Firmware updates are usually very small in size, and yes they do get charged against your usage.
No, the modem does NOT get automatically get rebooted every day (or night)
Reboots will occur as the result of an "overheat" *, one of the front LED's will turn RED as an indicator, or as the result of a firmware update, but should not go in an endless cycle, or as the result of a user doing a "on the fly" reset from the modems SCC.
Modems can also reset due to AC power losses AND an improperly seated connector (DIN connector) between the modems "power brick" and the plug on the back of the modem.
That sucker goes in HARD !. You would swear it was seated properly but it isn't.
That plug (modem rear) should NEVER be used to reboot the modem !
This can cause severe damage to the modem. That "plug" and those tiny pins were never intended to be used as a "switch:.
