The enet light shows any ethernet comms activity (local side of the modem) where as the send/recieve shows activity on the cable side of the forum, hence it's perfectly normal for the enet light to blink on the modem modems.

It will though depend on the chipset and how the lights are wired up. That'll mean that because it flashes on the modern modems it might not on the older modems
