Hello
Do you see the lights of 2.4ghz and 5ghz on amber?
It could be the regulatory domain which you put, which is the regulatory domain you put when you fist configured the Instant AP? maybe is a country that is not in compliance yet...
If its that then you need to factory reset the IAP and put in the regulatory domain Canada or US or something like that, and it will work.
Cheers
Carlos
