All devices are going to have an "IP Address" and if there is a conflict in those addresses then things are not going to work.
The IP address of the Hughes Modem is hardwired at 192.168.0.1
This address cannot be changed and it can not "shared" by another device on the network.
In many cases the default IP address of the Router in the same as or very close to the address that must be reserved for the Hughes Modem.
The suggested "LAN IP" address for a Router is 192.168.1.1
First lets look at the proper wiring:
(click on pictures for larger image)
Here is the rear of a Hughes HT1100 modem:
It has a single LAN port (looks like a phone jack but larger). This is the "output" port of the Hughes modem.
This is where a user would directly connect a single computer to the Modem if only using one computer or during any troubleshooting efforts.
It is also the port that will be used if a user elects to "network" their system by adding a Router.
The typical home Router has five (5) "ports" on its rear ... Four (4) LAN ports (Local Area Network) and a single WAN port (Wide Area Network) that is slightly offset from the other ports. On some Routers the WAN port may also be labeled as "Internet".
Here is the rear of a typical home Router showing all five "ports":
An Ethernet cable is used make a connection from the Hughes Modem LAN port (depicted by the red arrow) to the Routers WAN (or Internet) port. This will be the one that is slightly offset from the other Router LAN ports.
Networking 101:
Most consumer grade Routers consist of two parts: The WIRED and the WIRELESS portions of the Router.
Before a "network" can be used, it has to be "created" first and this has to be done through a WIRED CONNECTION.
When set up we will have something that looks like this:
All Routers are going to have a "setup CD" or "Install Wizard" and I strongly suggest that you DON'T use these "automated" installation methods and instead do "manual" setup.
The reason I suggest this is that true "Broadband" is so prevalent in the US that the Router manufactures assume that all users fall within that category and have certain internal Router settings configured in a manner that can have issues with a Hughesnet connection.
I do strongly suggest going to your Routers manufactures website and obtain the user manual and "quick start" guide as these will contain valuable information including a couple of VERY IMPORTANT TIDBITS:
#1: The "Default Address" (known as the LAP IP) assigned to the Router
#2: The default username and password needed to access the Routers internal settings pages.
The LAN IP of the Router if different than 192.168.1.1 is should be changed to that value.
Consult your Routers "quick start guide" for that information.
IF THERE IS A CONFLICT IT MUST BE RESOLVED FIRST:
#1: Disconnect the Ethernet cable between the Hughes Modem and the Routers WAN port.
#2: With a single computer directly connected to one of the Routers LAN ports enter the "address" of the Router as per the manufactures documentation:
Using the manufactures documentation reveals a conflict with my old Netgear default LAN IP:
Using that info, while connected to the Router LAN port and no cable between the Router and the Modem will allow access to the Routers "internals" after entering the default username and password:
An important note:
These default values MUST be changed to maintain network security and integrity.
There should only be ONE USER in the household that has the username and password to the Router.
Maintain a record of this info but it needs to be in a secure place !
Again, there should be ONLY ONE NETWORK ADMINISTRATOR !
Once that information is changed and entered you can enter and view the Routers internal settings including changing the Routers LAN IP to 192.168.1.1
All routers have a difference in their user interfaces as well as "bells & whistles" but some things are "universal"
Here are some suggested settings:
The LAN TCP/IP Setup is where you would resolve an IP conflict between the Hughes Modem and the Router IP.
Set it to 192.168.1.1 as shown in the above snip.
There are important aspects to consider yet such as Wireless setup and security and alternate
And is incomplete as it lacks links to the major Router manufactures, it lacks any details as to the risks of WPS, Remote Access, Wireless Encryption levels and so on and so forth that no one really wants to read anyway.
