How do you lower the power levels on an AP in one direction? One of my APs has way too much power in one direction. I'd like to pull it back a little. It is mounted on the ceiling of a room that is close to a wall of the building. It is broadcasting across the street.
You can't actually turn down power in one direction. The propagation of signal strength is determined entirely by your antenna, not the access point. If you turn the power down on the AP, it will reduce power in all directions.
What kind of antennas are you using? You might want to consider a directional antenna that broadcasts in one direction. Just keep in mind that there are always "leaks", and even a directional antenna will broadcast behind it a bit.

As for lowering power, you should be able to do that under the Configure -> Access Points in WCS.
