3802i and the death of autonomous ap

I am trying to set up a 3802i ap as an autonomous ap.  I now learned that I have to run mobility express.  I currently running 8.4.100 and cant get it to work.  It boot up and get to the end and the light just rainbow and I never see the ssid.  


So I tried to terminate the autoinstall and go manual, but the wired interface keeps flapping up and down and never connects.  the rainbow lights never stop even after configuring ssid. 


I did notice that this ap is only pulling 15.4 watts.  I tested this on 3850s with 802.3at(30w) and UPOE (60w) and still only 15.4.  this just doesn't see right.

I recently went through configuring one and one thing you need during the setup process is the management DHCP scope.  Thats how the AP gets its IP and can then join the controller.  I used the setup script to do the Employee SSID (survey) and DHCP scope.  I then statically set the channel, power and channel width in the GUI of the controller on board and both radios came up fine.

bad firmware when shipped.

I ask you Serial numbers to check this field notice.


it is the dumbest thing Cisco could have done with their APs and i will HATE them forever for this nonsense.


Cisco coders couldnt program their way out of a wet paper bag!!!!!!!!!!!!!!
