Cable modems constantly ping the network so you'll always get what appears to be constant traffic in the form of router/modem lights blinking. Nothin to to worry bout.

Activity lights on the modem and router are fine, even with no "real" activity. It's just the modem talking to the other ship.

Try this out. Disable wireless and turn off all networked devices. $5 the modem activity light still blinks.

The nature of DHCP and networking in general depend on broadcasts. There are a multitude of possibilities on what generates non user specific traffic. They could range from the router/modem pinging, arp broadcasts, snmp traffic and so on.

If you have any doubts, download and install ethereal/wireshark and take a look at the traffic.

Yes its fine, the modem is constantly sending QOS data back to the CMTS its also constantly broadcasting to the router and polling it as well this is all normal, I'd personally worry more if it stopped blinking myself lol. But yes like I said cable modem's tend to generate what appears to be a ton of there own traffic on a network.

^^^JermemyFr along with others are hitting the nail on the head. Also remember that cable is a always on connection, so blinking lights is good.
