Thanks for the replies
I troubleshooted this now for a week and I cannot find anything wrong on my end. For what it's worth I paste the advanced page.
What puzzles me is that the Target EsNo for ranging at 1/2 is 120.
I also checked out another system with the same configuration:
HN7000s, 2watt, .98meter dish, 127W/1381, same gateway. This site as well cannot range higher than 1/2.--
DW7000/.98m/2watt/Horizon1/1381 /Linksys wireless/Thinkpad XP pro/Toughbook CF-28 XP pro/Asus P53e, Win7Pro.
