Sounded to me like he set up his AP in about the middle (length wise) of
his house but closer to one of the walls on the long side (my house as an
example is more of a rectangle then a square - more frontage then depth,
I'm guessing his is too). What he is trying to do is light a room on one
end of the house and his deck which is on the opposite end of the house.
Again picture a rectangle not a square.
The orientation I suspect at least this is what it soumds like to me
regarding the antenna when he says point it. Most omnis that come out of
the box with APs are 'sticks' you can point them up, vertically or point
them in some direction, horizontally with the end (away from the back of
the AP where it attaches) in whatever direction the user desires.
Please note here I am not saying this is a good idea, a bad idea or
anything else icluding that it would have some big impact on radiation
pattern. I am simply trying to help you understand what I suspect he is
saying. Personally I don't see how orinetung the antenna horizontally would
help in this situation, but in his case, it worked. I imagine it worked
because frequnetly simply moving the antenna a few inches can often have
profound effects on the signal going where you want in a house full of
walls, windows, and metal appliances.
I moved the antenna and AP itself on my little linksys (G) an inch to the
left as I was looking at it the other day and my signal level on my laptop
in another room according to the little Windows display added two bars.
Best guess on my part I moved out of line with some wiring or conduit in
one of the intervening walls. Who knows, but the results are clear to see
(until the next time someone dusts the table the AP is on <grin>)

Again alter the antenna from vertical to horizontal is what I'm betting he
meant. Not saying this is a good idea, just sharing my 'translation'.
fundamentalism, fundamentally wrong.
