I've got 40 AIR-LAP 1131 APs, in our building. As I approach the 1 in the stairwell with my laptop, my signal strength drops from full bars to barely 1 bar when I get right in front of it(it's mounted on the concrete wall appx 7 feet high). Concrete walls, metal and concrete stairs, but I am directly in front of it. Also, I am using a 4404 Wireless LAN controller for all APs. Do I adjust the power? Any ideas would be greatly appreciated! Thank you!
Most Omni antennas have a donut-shaped signal, with the antenna stick being in the center of the hole.
When you start bumping up the gain, the radiation pattern tends to compress, and in some cases, radiate more towards the tip of the antenna (more like a flat cone, with the wide part aimed at the ceiling).
To test this, rotate the AP 90 degrees clockwise (so the antenna would be pointing to the horizontal with you facing the broadside) and see what affect it has on your signal. In this position, the "donut" is now vertical (would look like a car tire) and your system should have much higher signal strength (though not necessarily better signal quality due to the reflective nature of the walls).
Gain does you no good if you don't know the pattern and adjust for it.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.

I have created a Powershell script to automatically add a Wireless Guest User on Cisco WLCs. (tested on 2500 Series)
The script should be completely self explanatory.
