How can I monitor what my WiFi connection is sending?

I'm intrigues why the wireless connection window shows that I'm
"sending" a lot more data than I am receiving? I'm mostly accessing
internet sites and occasionally downloading but can't understand what
my computer is sending, even when I remain inactive?
Does anybody know if there is a way to monitor the activity and see
what is actually being sent? I fear that I may be sending data that I
don't want to be sent?
Many thanks for any help and insight or programs that would help me
monitor what is going on.

The sloppy way is to open an MSDOS window and use Netstat to see whom
you're connected with:
start -> run -> cmd <enter>
netstat -n (faster. no names)
netstat (slower. resolves names)

A neater way to do the same thing is TCPView:

However, this does not give you any control over outgoing connections.
That requires one of the Personal Firewall solutions. ZoneAlarm,
Kerio, Norton Security, McAfee, Black Ice Defender, etc. Each will
allow you to configure which programs are calling out.

If you have substantial outgoing mail (port 25) background traffic,
you probably have a Trojan Horse that is being used to distribute
spam, viruses, and what not. I suggest you update and run your virus
scanner. If it shows nothing or doesn't function, try one of the
online virus scanners:

Once the name of the trojan is identified, you can download and use a
dedicated removal tool.

For monitoring at pretty much the lowest level, you can watch all the
packets being sent and received over your network interface. A free
Windows program for that is Ethereal:
