@templedf,

Glad you were able to get it figured out, the extra ports on the router from your ISP is usually an indicator that either the router can have its own wireless connection or is a more advanced modem that can handle aggregating multiple networks, or in some cases, it is just a digital phone line.

One thing to note since you mention that you have a router at the head of your network; if the device is broadcasting its own signal, you would want to enable either bridge or passthrough mode. Otherwise, you will need to use the Decos in AP mode as there will be conflicts between the addresses assigned by the deco and the router.

Out of curiosity, did the Deco only go offline when you were using devices or sending traffic from the satellite deco through the switch directly to the router? I am curious if the switches connection was attempting to reconfigure itself as having a WAN connection.
