TX Power Level

[gcook0001]

We currently have three AP2802i access points running version 8.10.105.  One of them is acting as the controller. 

I have run the Cisco wireless adviser and a wifi scanner and they both come back with the same thing.  I need to raise the TX level.   RSSI is running about -68.   The problem is I have researched and everything I find on how to accomplish this does not work (ie. type in this command and the command does not exist).  I have spent hours looking at the different commands in the CLI without success.  How do I manually increase the power level on these access points.

If you have at the outer edges of the coverage are -68 dBi, then you are actually good.
For the power levels, you can either choose TPC (recommended) or manually set the power.
Look here (search for power level) on how to set it manually per AP and Radio:
