I bought a 2 pack of the W3600 Deco unit, and one of my Deco's won't finish the startup process and become discoverable for WiFi setup. I was able to get one connected and setup, and I following the steps listed on the app for setting up an additional Deco but I'm unable to connect for the WiFi network portion.

The light stays yellow for approximately 1-2 minutes, goes to pulsing blue for 10 seconds, then solid blue for 10 seconds, then it goes back to yellow and repeats the cycle. I've tried to connect during the entire process but I haven't had any luck. 

I've tried all the essential steps, e.g. turning it off and on again, reset button, change location, and I changed the power cords around. 
I hope I didn't get a faulty device and assume there's an easier explanation for why it's being difficult.
