Wireless Access

Im running a 7005 controller with a single AP-335 for my home lab.  I'm running AOS 8.2.2.3 and the controller is standalone (no Mobility Master).  Nothing I seem to do seems to actually increase the EIRP though, it's almost like it's locked in place.  Using both the GUI and CLI to modify the Radio Profiles, I've been trying to just set the EIRP to Max, but there is no change to the AP transmit power:

# show ap radio-summary

Here's the relevant portion of the running config:

rf arm-profile "default-a"
    min-tx-power 127
!
rf arm-profile "default-g"
    min-tx-power 127
    free-channel-index 40

rf dot11a-radio-profile "default_radio_a_ui"
    arm-profile "default_radio_a_ui_arm_a_ui"
    am-scan-profile "default_radio_a_ui_amscan_a_ui"
    eirp-min 127
    eirp-max 127
!
rf dot11g-radio-profile "default_radio_g_ui"
    arm-profile "default_radio_g_ui_arm_g_ui"
    am-scan-profile "default_radio_g_ui_amscan_g_ui"
    eirp-min 127
    eirp-max 127

What am I missing?

The max regulatory EIRP for that AP for an 80mhz channel on channel 48  is 17.5.  you are already at 17.5, which is the limit.

Run this command:

show ap debug power-table ap-name <name of ap> radio 0

That will tell you the maximum transmit power for 20/40/80mhz wide bands on each channel for that access point in your current regulatory domain. 

Here's the output:

#show ap debug power-table ap-name ap01.office radio 0

Channel 48
Bandwidth:80Mhz
Actual Antenna Gain: 2.5
Connector loss: 0.0
Effective Antenna Gain: 2.5
Override board limit: 15.0
Antenna Polarization: Cross Polarized
Number of Active Chains 1
User Configured Power(EIRP, dBm) 18.0
Min Power(EIRP, dBm) 2.5
Min Power (Conducted, dBm) 0.0
Effective User Configured Power (EIRP, dBm) for current active chains 18.0
Effective User Configured Power (Conducted, dBm) for current active chains 15.5

I'm trying 40 MHz channels to see if that'll increase it

The radio-summary output already has the max:

ap01.office  default  335      192.168.1.130  5     AP:VHT:48E  17.5/17.5

Looking at the power table says what the max would be on other channels, but it is not  more than 18, on any channel/width combination. 

Well that's very very important to know.  I was looking at replacing our 325s, but with the max power that much lower, it may be worth revisiting this plan.  Thanks for the help

It all depends on what you are trying to with with that access point.  What is the environment that you are trying to support?

What requirement is not satisfied by your 325s, that you would consider 335s?
