I infer you are looking for a WiFi router to use inside the boat to share the link from the Rogue Wave to shore? Nearly any router will work. I particularly like the Linksys WRT54GL as it is stable, reliable, and you can lop the wall wart off the power cord and wire it directly into 12VDC on the boat.
