wireless outdoor access point

[percypineapple]

Hi Gents,
i have purchased a engenius eoc2611p. I assumed that this would just fit to the outside wall, then a lead from there to the little mains adaptor device, anothe lead from there into the existing router, and that would be it, I would be able to pick up my wireless signal at a greater distance. but, woe, you need to be a genius to understand the set up, and it seems that you plug it into your computer, not the router, so defeats the object. There is a video on you tube, an epic, by the time it got to the end i had forgotten the beginning, although it seemed to concentrate on two units, not one. anyone got any ideas apart from throwing it over the hedge?
