How can i find out if people are using my Internet service via wireless
I guess it is called piggybacking, people via wireless 'using' your Internet service

I have two computers,both of them use a wireless adapter to connect to my modem.
I use a password to connect to my Internet service.i am wondering if anyone else may be
piggybacking off my Internet service?

i am wondering if there may be a software program that specializes in exposing

[windows 7]

thanks ahead of time for answering

Your router most likely has a page to view who is currently (and recently has been) using your connection. In my router I go to Attached Devices or Device List. On DD-WRT flashed routers, this is under the Status -> Wireless screen. You will find a list of all the IP addresses currently being used.

On my router, I found a list under the IP filtering section.

SRC: MakeUseOf

To prevent leaching:
  • Enable Encryption (WPA/WPA-2)
  • Change your router login password
  • Enable mac address filtering
  • Disable broadcasting of SSID
  • Use a WiFi portal
  • Install a firewall (I recommend Comodo) if you don't already have one
If you would like to before hand, you can have a little fun with the leacher by turning their webpages upside down while their leaching off you. As for programs to detect leaching, without going into all the cool-nerd detail, WireShark would help you most. Although rather sophisticated software, once you learn the interface you should be able to detect abnormal behavior using the filtering views built in.

What makes you think your connection is being leached? If you need help settings anything up just tell me! If you could give me your router details I'd be happy to point you to some tutorials specific to your model.

Helpful resources:
-Monitoring your security
-Hiding a wireless network
-Monitoring a network for leachers
-Check to see if your network is being piggybacked
