Aironet's biggest enemy is water. Trees are made up mostly of water, and
therefore the signal is unable to penetrate branches or leaves. My only
suggestion is to cut them down or put the bridges on top of a tower or find
some way to bounce the signal around the trees.

Yes, the signal go through trees, but you will need to calculate your
db losses correctly and take the trees into account.
You'll need to ask yourself these questions:
How many trees are there?
How dense are the trees?
etc.etc.
Check out this link:

What model and antenna are you using? How thick is the vegetation?
I setup a building to building wireless link this summer using BR342s on
each end, with a Yagi high-gain on one side and a omni high gain on the
other. The distance was approximately 400m through approximately 100m of
tree can
No. You need clear line of sight. The Aironet will cook the leaves.

How does one bounce the signal? With a third access point, like a triangle?

or a mirror 6' x 6' should do the trick
just hang it from the tree you want to bounce the signal around and as the
wind blows the mirror will turn to the correct angle.

with a repeater, or you could put a third access-point in. have you
calculated your loss budget yet??? do you need to bounce the signal?

Not real sure how to calcualte loss budget. I'm going to just have to
increase power and hope for best.

Steven,
Coming from a WISP in Southern Cal...Aironet will not go thru trees w/
vegetation. It is true line of sight, trying anything less than LOS will
result is some horrific Radio Re-tranmit errors that will play and wreak
havoc on the link. (Basically making it an unuseable link...)

Technically, it's not really line-of-sight, eh? It's radio waves, not
light. It's not a laser solution, for example. But radio waves are
reflected, refracted, absorbed, etc. by all sorts of things, especially
bio-masses.
