Been in touch with netgear, but also no one has a clew about what´s wrong. Should be working, should work on any normal PoE switch... this is becoming in a time consuming operation, instead of an easy and smooth upgrade.
First time using Meraki products, and probably the last time also. Was about to go for Netgear WAC or Linksys LAPAC units, but after hearing about Meraki, and seeing the "cloud" capabilities, comparing prices, maintenance, I decided to get 3x units Meraki mr16. Glad I didn´t purchased the license yet, and was on the 30 day trial, that was enough time to see the troubles I was getting in to.
Due to the cheap cost of the hardware, not much was lost, and probably going to flash the DDWrt or Cucumber on them and going straight to Ebay.
Too much effort, to many switch problems and PoE compatible issues, to many picky settings, just to make them confortable working. In the end, end user want a reliable working product, without needing an IT guy every week just to adjust setting or to keep them going.
At this point, I wouldn´t and won´t recommend Meraki. Want hard and working? go for main company Cisco or Motorola. Want easy and working? Go for Linksys, Netgear, whatever... Want easy, but not working all the times? Go for Huawei (lol :D) but never go for Meraki.
Probably no DHCP on the PoE port ? Have you test by connecting to the port with a laptop to see if it can grab an IP? Note each MR16 will require 10.5 W hence it should work for 1 or 2 AP? Probably Power not enough? (If DHCP IP able to grab from a laptop) I recommend you to try on a pure PoE Switch instead.
