192.168.0.1, then click on the little "I" icon near the top center. If I recall, you enter your lat/lon in decimal format (GPS coordinates are best) - but the ones the installer used are probably already in there. Correct if necessary, then click NEXT. I think that puts you on the signal strength page.
Accurate gps coordinates are extremely important. It determines what beam you're on & also calculates the distance from your dish to satellite during ranging for proper output. Unless your an installer with access to the hughes portal & ovt there is no way to tell if you've properly tuned your dish. If having a problem it would be best to go through hughes tech support. There is a high likelihood your system is still under warranty. If moving dish to another location your current coordinates will likely throw a flag during registration & not let you go any further.
