My Lan always shows connection and packets being sent & rec'd, even when modem off. What's up and how do I fix? Thanks!

Kim: Why would you turn your cable modem off? The purpose of a cable connection and DSL [other than higher transmit - receive speeds] is an "always on" connection.

Anyway that is the way it is supposed to work. The ISP is pinging your connection to insure that it is available or other technical reasons.

Kim noted that her "LAN" shows packet activity even when it is not connected to the Internet via a Cable Modem.
 
This is normal as all devices on a LAN communicate among themselves via TCP/IP/UDP packet exchanges.  Connecting a cable modem to your LAN adds another source/sink for packets.

Signature: 127.0.0.1, Sweet 127.0.0.1 and I recommend all of these Anti-malware tools and Procedures. (updated May 2010)

As was said this is normal and the activity likely contains A.R.P. traffic as well.
