I have 3 "eeros" and another 3 "eeros pro" at home all of them in AP/bridge mode and wire connected to the router. I decided to change one of the eeros pro ubication and, suddenly, it got sutck blinking white. For almost one week I've been trying unsuccessfully everyhing: customer support by email and by phone, community help, google,...It has been very frustrating.

Finally I received and email from customer support asking for a lot of information including the power adaptor serial number. This request was unsual an, in fact, very weird for me and, then, I saw the light: eero pro needs its own power adaptor of 25W and does not work with the 15W adaptor of the standard Eero. That was the problem.

So, every eero with its own adaptor, otherwise you will have blinking white problems.
