Stef,
What WiFi system are you running? Some of the older ones have a weaker signal. I use one similar to what Uberlanders has and mine has a range of about 250 feet give or take. It works great out back in my AS. I also use a repeater at my inlaws house and a beam antenna to reach the barn repeater about 400 yards away. Mine is normally encrypted...but I have been having some issues so it is running barefoot at the moment, however given where I live the only way you are going to get to my wireless is by helicopter...so if I see on hovering
