This is really strange.

I have been using my AV1000 Lan adapters for a few years now.  I have used them with a wireless router and for almost a year with my Deco Mesh system.  I have the lan line from the cable model to 1 Deco on the line in and a lan line from the Deco to an adapter.   From that adapter it feeds the house power lines to other adapters. 

Now all of the sudden,  every adapter has the red blinking light.  My 2 tvs can not connect to the internet but my media server still can connect to the Internet. 

I have tried pluging the adapters into other sockets and they still blink red.

Any thoughts?  Could something have happened to my home power lines or something with the Deco?  ( we did try rebooting the Deco too)
