JUst unboxed the router and started the installation.

Downloaded te deco app. App identified the router, connected to the native wireless. 

It then startes with detecting internet connection and give this error.

I get an error an error " It looks like Deco is not properly connected.

1. Check if the Ethernet cable is plugged in properly"

The cable is fine . When I connect it back my old router (netgear) it works fine. After this error message the blue light becomes solid for a few minutes and then starts blinking again.
