In case you want to play with Wireshark...
I suggest installing it on the desktop system, setting the filter to ICMP,
and then pinging from laptop to desktop and desktop to laptop. The following
screen capture:
<http://www.ownvolition.com/Wireshark%20pings.png>
shows Wireshark running on the stand-in "desktop", with a ping from "laptop"
(.101) to "desktop" (.152) - Nos. 943 & 944 - and one from "desktop" to
"laptop" - Nos. 1153 & 1154.
