Here's what I'm looking to do:

Network two houses, no LOS (trees). Basically I'd like to bounce down to a garage, then up to the second house.

The garage is close enough to both houses that a G router has enough juice to get signal at both houses. WDS over hacked Linksys 54G works fine, but obviously a consumer G router isn't going to last through summer and winter temps very long.

There might be point to point that could bore through the trees (house to house is maybe 500ft at most). Most point to point I find though is commercial stuff in the $2K and up range. Nope, don't want that.

Trying to avoid running ethernet cable down to the garage to an AP, but that's also an option depending on how expensive the point to point options get.

Hey I'm an F'n Jerk!
