@tsthrone,
When all three of the nodes turn to red, it usually indicates that there is an issue communicating with the outside network, such as an IP address not being set correctly, or a temporary lapse in connection from your ISP.
Something to make sure of: If you have a modem from your ISP, make sure that you have disabled any wireless functionality or any routing settings by setting the modem to operate in Bridge or Passthrough Mode. If the ISP modem is managing the network connections, it is possible that the deco network is being assigned a new address from the modem, causing the disconnect.
When the disconnect appears to occur, is the internet connection lost on both wireless and wired clients? I have seen similar behavior where the lights will flash red when the wireless network goes down, but the wired clients still have a connection.
Lastly, who is your ISP, and what modem are you connecting the decos to?
