Lets look at possible issues: ( with the understanding that at times two routers may be needed depending on the "shape" of a users network.
One thing to keep in mind is that if the first router does not have DHCP enabled then the "router" part of the Hughes modem is tasked with handing out IP addresses to the connected devices.
The HT1000/1100 modem has a DHCP limit of only 5 devices ..... if two routers are connected as AP's then they will take two of the available IP's right off the top.
#1: connect a single computer directly to the Hughes modem: DO YOU HAVE AN INTERNET CONNECTION: Y/N ?
#2: Disconnect the cable between the computer and the Modem and leave the modem out of the loop for the moment .......
#2a: Connect am Ethernet cable between the COMPUTER and one of the ROUTERS LAN ports. (remember .. no modem connected .. we are NOT looking for internet at this step.
#2b: Power up the ROUTER, power up the computer .... enter 192.168.1.1 into a browser ..... DO YOU GET THE ROUTERS "LOGIN PAGE" ? Y/N ?
If yes, go to step 5 If No, enter 192.168.0.1 do you then get the routers login page ? Y/N ?
#3: If 192.168.1.1 does NOT take you to the Routers internal setup page then the routers assigned LAN IP is misconfigured and is likely in conflict with the Hughes modem.
#4: I'm not on my computer so I don't have my normal stock of pictures at this time. We now wish to connect the Routers WAN port to the modems LAN port. We wish to then connect a single computer to one of the routers 4 LAN ports
Due to a lack of pictures tonight I would like you to view a "how-to" I have posted ar the Shack:
