Cannot connect Time Capsule to Brightbox 2

.....and just bought a Time Capsule (3TB). I connect it up to the WAN on the BB2.....

The correct connection would have an Ethernet cable connecting from the WAN "O" port......on the Time Capsule.....to one of the four yellow LAN <---> ports on the Bright Box.

Is this what you meant to say?

I connect it up to the WAN on the BB2 and only get the flashing orange light. No connection. Any ideas? Thanks

You are connected to the wrong port.. You cannot to one of the Yellow LAN ports.. not the RED WAN port.. that is for internet connection.

Since the BB2 is a full router you will use the TC in bridge..

So LAN BB2 to WAN TC, and if you have not yet done the setup.. full factory reset and start over.. the TC must be in bridge.

You responded to your own post.....but it appears that you now have things set up correctly.
