I have not opened up in innards of the laptop yet... but I will if you need 
the information.

Sorry that I didn't include it before...

Heh, I know more about networking than this : )  My Linksys broadband router 
is a switch, which is why I bought the 4 port hub... which I should beable to 
sniff from. To describe my setup another way...

The 4 port hub has 3 connections to it:
1. Laptop trying to sniff - 192.168.1.14
2. Desktop pinging (or otherwise being noisy) to my router/switch 
	- 192.168.1.13
3. Router/switch (connected via uplink port) - 192.168.1.1

So I should beable to see any traffic between the desktop and any other 
computer in the house (or Internet) because it all passes through the hub, 
which the laptop is connected to.

Thank you,
