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 have 1130’s, 550’s, and 250’s all with manually configured transmission rates at 20dBm. I live in the US. My country code is 840 on all my AP’s.

[ashley_finch]

APs of the same model or different models?

What's the country you're in and the country code of the AP? (you can add this column in the manage page of the HiveManager)

[sbarnabas]

I dont think this is the case. I have other AP's that are hard set to 20dBm without any issues.

[ashley_finch]

Likely depending on your country that you're just at the regulatory limit looking at the EIRP
