Try the long distance WiFi thread as well. But...over a year ago I was trying to figure the same thing out. (Technology seems to have changed quite a bit since then.) I purchased the Alfa AWUS036H (I think...it's on my boat and I'm at home) I would point out that this requires two USB ports
to get the electrical
power needed to drive it. I also purchased two 15 ft active USB cables
. I've used it in different ways, depending on how far I am from the WiFi router that I'm trying to access.
Sometimes I just hook it to my laptop
and set it on the table in the salon
. Sometimes I open the hatch
and just set it on the deck
. If I really want to get some distance I hook up the two USB cable extensions and run the Alfa up one of my flag halyards almost to the first spreader. I can do that and still run the cables
through the hatch
and sit comfortably in the salon
. It doesn't work in bad weather
though because nothing is waterproof.
The one thing that I would do (and will do soon) is to purchase
an 8 dB omnidirectional antenna to screw on the Alfa. I suspect that will really increase the distance. But even now I can get over a half a mile, usually.
This is a pretty cheap
and painless way to go.
