I'm using a AP-650 connected to a RF4000 version 4.2.1.0-005R Looking at the new AP-650 I still not understand Desired Power (dBm) tab limitation. I set the country code to Italy If I look to the desired power output (dBm)  for the AP-650 real radio  RADIO B/G/N ranging from 1 to 20 (100 mW) RADIO A/N is ranging from 1 to 19 (80 mW) Under the Access Port Adoption Defaults instead both desired power output range from 1 to 20 (100 mW) Is and hardware limitations ? Only apply to World Wide AP650 ? Looking at the Access Port Adoption Defaults the Maximum MUs is grey out and report 127 (the maximum for Ap7131) Lookink at the Access Port Adoption for the AP-650 is set to 256 Is not possible to set a Max MU for AP650 and AP7131 globally ? I need to set it manually for each radio's Or is just a GUI issue ? Cheers Alarico
