How do I detect someone is using my wireless internet equipment?
Answers:
log into your router and veiw who is connected.
You can check your router. It will display the DHCP clients it has assigned IP address to.
If you have DHCP enabled on the router you can go to the router direction screen (usually by going to http://192.168.0.1 or http://192.168.1.1 in the browser) and vista the DHCP client list. This will tell you the ip address that your router has assigned. Some routers also have a log wallet of recent activity that you can examine.
As others have indicated, you may know how to determine IF anyone is stealing your bandwidth, but determining WHO is another story. It also has no effect on what will happen tomorrow, or the subsequent ten minutes, for that matter.
Instead, why not harden your framework before you need to? Here are my recommendation.
Because routers differ as to details, I can't be specific about how to accomplish these steps, but they're almost all done from inside the router's administration pages.
1. Change your SSID (Network Name) from the evasion. Hackers know that routers come with default SSIDs and look for them.
2. Turn sour the SSID broadcast from the router. There's no need to advertise your network's presence. You're not running a hotspot; everyone who should be on your make friends should know its name.
3. Set up encryption with an encryption push button. The longer, the better.
4. Limit access to only the computers you want on the network via MAC filter. (MAC refers to unique NIC (Network Interface Card) addresses, not Macintosh computers, and not IP address.) This isn't a defense against hardcore freeloaders -- it's possible to fake MAC addresses -- but it keep out casual interlopers.
5. Change the range of and/or restricted the number of automatically assigned IP addresses (DHCP) to reduce the destiny of extra users. Again, hackers know what ranges routers come from the factory with. Changing them makes it for a time harder to hop on board.
6. Deactivate wireless access to your router's administration trellis pages so only a computer connected via an Ethernet cable can conquer them. Even if you don’t want to leave a computer connected via a cable, leave the cable nearby for when you need it. Here are some the horror stories of some who didn't:

That should go far toward harden your wireless network.
Open the command prompt, (type cmd after clicking run in the start menu). Then type "arp -a". With a space between arp and -a. This will display all ip address connected to your network.
