You need to be aware of the fact that Hughes will refill your data allowance daily for the first 10 days (HN9000 Modem) or 20 days (HT1000/1100 Modem)
This is done to allow you to update all your devices with impacting your data allowance when you first connect to the service.
I have both Hughesnet (12 year user) and Directv (since November '94) and I can tell you ... you do NOT want to have any connection between the two systems. None at all !
The directv box will eat your data allowance alive with just program guide updates let alone anything else. Streaming of movies on a data capped service such as Hughesnet has to be done very carefully, very sparingly. Video quality needs to be reduced to the very minimum.
In addition to using your data at an alarming rate if connected, it will also effect your performance in respect to apparent speeds.
Your Hughesnet "data pipe" is very small compared to ground based services .... That "data pipe" can only support so much activity at any one time. The more you have connected the slower each will become.
While it is possible to view videos and movies on a Hughes connection a user needs to understand the systems limits including data caps.
Videos and movies are very data intensive and can deplete your allowance at an alarming rate.
Simply put, you don't want any connection at all between your Hughes system/network and your Directv service.
First, look on the back of your Router ....
There should be 5 "ports" in total.
One of those ports will be offset a little to one side and will be marked as WAN or "internet" port ... it will have a Ethernet cable that runs from there to the modems LAN port:

Rear of Hughesnet Modem:
A cable will run from the Modems LAN or "output port" to the Routers WAN port:
You do want the cable that runs between your router's WAN port and the Modems LAN port as depicted by the red arrow.
Then look carefully at the cables connected to the Routers four "LAN" ports.
It is fine to have a computer "hardwired" to one of these ports.
If you however have a cable that runs from one of those four ports to the rear of your of your Directv receiver you will want to disconnect that one.
Also ... look on the rear of your Directv receiver and see if you have any "USB Dongles" connected to the back.
Access to the Routers "front end" needs to have the username and password reset from the router manufactures default values.
This is done to ensure that no one has access to the routers internal settings.
This is necessary to protect the integrity of the network.
in the modems "internals" ...
WPS should be disabled
Remote Access should be disabled
QoS or that router manufactures equivalent should be disabled.
On the Wireless side .....
All "guest" accounts should be disabled
The "wireless" functions of the router need to have a solid encryption method set up.
You DO NOT want to run an "open network" because any and every device that comes within range of your router will be able to latch onto your service and use your data without authorization or authentication.
These are the most common encryption levels ranging from NONE to ....
WPA-PSK [TKIP] + WPA2-PSK [AES]
Setup and use at least WPA2-PSK [AES] at the absolute minimum.
If you have any question ... please ask.
Post screenshots of your router internal settings of any and all areas if you are unsure.
Your router has a "front end" IP address in the same manner as the Hughes Modem having an address that gives access to its internal pages.
The LAN IP address of your router needs to be in a range that does not conflict with the address of the Hughes Modem.
The Hughes Modem is hardwired for a IP of 192.168.0.1
That will give you access to the Modems SCC:

The LAN IP of your Router needs to be in a range that does not conflict with the Hughes Modem.
A suggested LAN IP address for a router is 192.168.1.1
Entering that address should bring up the "log in" window to the Routers "internal settings pages"
The router comes with a default username and password that varies by manufacture.
The default values MUST be changed to maintain the integrity and security of the network.
This info should only be known to one person in the household .. the one that maintains the network.
If you have ANY questions as to the above .. please post.
