Make sure that the satellite is connected to the yellow Internet port on the router. The server and any other computers should be connected to the blue LAN ports (or use wireless). It is a common mistake to accidentally connect a blue LAN port to the broadband (in your case satellite). By doing that you essentially leave out the router and instead end up with just a switch. The result is usually intermittent access to the Internet and other computers.
Start with one computer connected to a LAN port on the router. Make sure that the LAN port is configured to obtain an IP address automatically. You should be able to access the router using a web browser by typing in the routers address. For example:
If you don't know your router's address, the easiest way to find that is to display information for the Ethernet interface from a Linux root shell prompt. Type in this command.
With only one Ethernet cable plugged in, you should only see one Ethernet interface that is "UP" and has an IP address. If you don't see any Ethernet interface that has an IP address then your Ethernet interface might not be set to obtain an IP address automatically. If no Ethernet interface is UP then you may have the cable connected incorrectly.
Next you want to find out the default gateway. That is usually the address of the router. Type in this command to display the routing table and the default gateway.
At that point you should know the address of your router (on your Local Area Network). Type the address in a web browser. Log in to the router. The default password is "admin". If you have trouble getting the router's logon page to display in your browser, unplug the satellite from the yellow port on the back of the router. Type the following address into your web browser.
If you still can't access your router, you might have to reset it to factory defaults. That will enable the DHCP server on the router and reset the password to the default.
After you can log on to your router, then make sure the satellite is connected to the yellow port on the router.
Check the router status using the web browser and make sure that it has an Internet connection. If it doesn't you may have to change the type of Internet connection. Based on your description of the problem, you probably need to set your Internet connection to use DHCP (or obtain an IP address automatically). Also, you probably have to disable (or not use) PPP or PPTP. Some satellite systems require 802.3 protocol. Your router might not support that. The manual wasn't very helpful when I tried to check for 802.3 support.
There is another gotcha that you might run into with satellite. It's possible that your satellite interface (or modem) has the same exact network address as your router. In that case everything will work great for the router and computers talking to the router until you connect the yellow Internet port to satellite. To tell if that's a problem you can connect one computer directly to the satellite. Let the computer automatically obtain an address from the satellite Internet. Use the "ifconfig" and "route" commands to find out the information for that Ethernet port. If it is the same network address as the router or very similar, then you may have to change the router's network address. For example, change the router to "192.168.2.1" or "192.168.55.1".
After you have the router configured and the yellow Internet port connected to the router, you should be able to see that the Internet connection status is good on the router's configuration pages. Verify that the Internet is working on the computer that is connected to the router. If that is working you should be able to add other computers.
To add other computers you need to make sure they are set to obtain an IP address automatically, or you need to manually assign them an IP address. If you manually assign addresses you should reserve them in the router's DHCP settings so that they aren't also assigned to some other computer. Even when a computer obtains an address automatically, you can reserve its address in the router's DHCP settings. That is helpful to make sure that a server always has the same IP address, for example.
After computers have obtained an IP address from the router or have been manually configured they should be able to access each other. You can use the "ping" command to test access to other computers. Use the "ipconfig" command first (on the other computer) to find out its IP address. That's also helpful to verify that each computer has an IP address. Here is an example of a ping command.
Wireless adds a little bit more configuration that must be done before computers can obtain an IP address. You have to configure a name and passphrase for your wireless network. You configure those things on the router first. Then you connect to the wireless network from each computer, by selecting the network and entering the passphrase. You may also have to select the correct kind of encryption.
If you are having problems accessing wireless or accessing the Internet on more than one computer, the place to look is in the router settings. Go back to a computer that is directly connected to a LAN port and make sure that you can get to the router's login page. Look at the router's status. To use the "www.linksyssmartwifi.com" address to look at the router you must disconnect the yellow Internet port. It's better to use the actual address of the router since you can leave the yellow Internet port connected.
In order to access the Internet, computers have to also know the address of a Domain Name Server. That is usually the address of the router. The router's Internet connection should have the addresses of the real Domain Name Servers. You can see that by looking at the Internet connection status on the router's configuration pages.
If ping is working and the default gateway looks correct, you can test the name service from a computer using this command.
You should get back a list of all the IP addresses for GOOGLE. This is one of the last things to test because everything else has to be working in order for this to work. When you can ping the other computers and the router, you have the default gateway configured correctly and a good Internet connection (according to the router) then this should work. If you can't access the Internet, test with "nslookup". If "nslookup" fails, then check the Domain Name Server settings on the computer and the router.
You didn't really say what the server computer does. If it is just a file server then it does not need any special configuration other than setting up a permanently assigned address in the router's DHCP settings. To use the server as a Domain Name Server or router then you have to make other changes to the server, router and computers on the LAN.
If you have some other special configuration then post exactly how the satellite, router and other computers are connected. Post the IP addresses and routing tables from the computers ("ifconfig" and "route" commands). If you don't see the Ethernet devices you expect with "ifconfig" use "ifconfig -a".
