Why is my 1130 only transmitting at 15dBm when I have manually configured it to transmit at 20dBm?

[sbarnabas]

I have an 1130 running 10.0r7a and I have manually set the power transmission to 20dBm.  I recently changed the channel selection from auto to a manually set channel and pushed a full config update to the AP. Now it will not transmit more that 15dBm.

I set it to channel 11

What channel are you selecting?

Regulatory limit=23dBm(1) 15dBm(2) -(3) -(4) ;

Freq(Chan)=2462Mhz(11*); EIRP power=23.01*dBm(15dBm + 5.00dBi + 3.01dBi); Diversity=enabled;

Seems your at a regulatory limit.
