I have done numerous searches and have found little if any help. I was capturing packets with etherreal on my suse/i686 box. I have a cable modem connected to a Linksys WRT54g with the sveasoft firmware upgrade. I have noticed there are numerous STP packets spewing forth from the router every couple of seconds all of which appear to be identical. Just a couple of questions - 1: Is this normal 2: Is this necessary if no other routers or switches are part of the LAN
