What is this traffic?

I'm new to wireless. I just set up a new Buffalo wireless router,
model WHR-HP-G54 using an ethernet cable. And I have some strange
traffic between my computer and the router that I need to
understand.

Sorry, I hit Send by mistake.

Anyway, it appears to be once each second, and bringing up Status of
the internet gateway shows it's 30 packets sent, and 24 received,
each time. In Netstat I don't see any established connections that
would account for this activity.

I've disabled the radio completely in the router, in an attempt to
isolate the source of this traffic, but that didn't make any
difference. I also tried putting the SB5120 cablemodem into
standby mode, but that didn't change it either. So it's between the
computer and the router, but with no established connection that's
shown in Netstat.

Is this a periodic handshake between the two devices to make sure
they are still there? Is there any way I can turn it off?

My guess is that it's UPnP, a service on your computer that allows you
to configure your Router from your computer without going to the web
interface.

you could download a protocol sniffer like EtherDetect
and see what the traffic looks like....
That's what I use when things look weird around the router LEDs.
Maybe some kind of monitor was installed & is running ?

If XP, try the ctrl-alt-del and take a look at the activity.
