This is my first post, so be gentle...
I am trying to learn how to control the tx power of my access point.
After my system is up and running I attempt to lower the txpower using
"iwconfig wlp1s0 txpower 15"
The system accepts the command without complaint and a subsequent iwconfig
wlp1s0 command yields:
wlp1s0 IEEE 802.11abgn Mode:Master Tx-Power=15 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Power Management:on
However, monitoring the airwaves with "inSSIDer" (Windows) or the Android
"Wi-Fi Analyzer" I see no drop in measured output power.
What am I doing wrong??
