You will have to log into your Access Point to view active client connections.   I suggest you use WPA security, so you do not have to worry about someone hijacking your connection.  I could help you further if you provide me a make and model of your access point\n\nScottsdale, Arizona Computer Repair & USA Phone support\nhttp://www.AFFIRMATIVE-COMPUTER-TECHNICIAN.NET\nAffirmative Computer Services \n*Quality* Computer Repair Services

You could log onto the routers maintanence page and see wh ois connected to it, and see fi it has a logging function you can use to see who logged on previously.\n\nThe best way to stop other people to use it is to change the "SSID" name to one only you know, connect up your laptop and the turn "SSID Broadcast" to "off" so nobody can see yoru signal unless they know what it is called.\n\nUsing security like WEP etc. will also help stop unwanted people

If you have the machine they are downloading from then you can just do a netstat to see where the connections are coming from.\n\nIf you do not know where they are downloading from then you will need to get a program like ethereal (packet analyzer) and set it up on a port on your switch that sees all local traffic.  It will record all of the traffic and provide analysis to show where the traffic is coming from.

I take it you are on a wireless network. You need to adjust your security settings on your computer.

You can check to see how many addresses are being handed out if you AP provides DHCP service.  Even if your AP doesnt provide DHCP and someone is just associated to the AP then there should be a screen or some sort of log that shows you who is connected.  It will show you the MAC address unless you have some other sort of authentication set up.\n\nIf your AP provides firewall service also, then you can check all outgoing connections as they are being built to see where they are going.

Yes, there is. Install an application like nagios (freeware) or Look@Lan (freeware). Have that monitor the IP address of your router.\nBut it's usually not easy to understand all traffic that is going on in your network.

Go to Start>Connect To>Show all connections. Then right click on either the Local Area Connection or the Wireless Connection (if you're computer is connected to the internet through a wire, right click on local area connection, otherwise do so to the wireless connection). Click on properties. Then, check the box that says "show icon in notification area when connected." Click OK.

Nortornis to secure ur computer. But if u have wireless modem other wireless user will certainly be able to see ur network. So you will have set up for the wireless modem. Better call ur ISP tech support n ask them to enable security on the modem. U can email me at..nithujns@yahoo.co.in

If they know their static IP or happen to know what their dynamically allocated IP is(highly unlikely), they can use the 'ping' command from the command line editor of Windows.  \n\nMost firewalls drop ping requests, so if you're behind one, it's not likely that they would know if you're online.  If you aren't, however, and they know the IP, they would get a positive response and discover you are online.

It sounds like your wireless connection is secured. You need to login to the wireless router and look for the password or passphrase section. See router website for details on this.

If you are using a router it should have a log capability.  Log onto the router and check the log.\n\nIn addition the previous answer mentioned keyloggers and goggling.  However I suspect they would be detected by an antivirus.\n\nI would also suggest that you look for any thing spying on your machine.  Kids are pretty smart.

I suggest you LOOK@LAN it's a very good network scanner. It deeply scan your LAN and list all computers with all active services on them.

Yes, make a secure connection or use a program like Anonymizer that encrypts the wireless.

Go to Start - Control Panel - Network and Internet Connections - Network Connections.\nif you have a network card it will show it, whether is wired or wireless you will see it in there.

If you log into your router, you can look at the lan configuration and see what computers are using the network, but if you are using WEP encryption, it should not be an issue anyway.

In a direct connection, your "buddy's" IP address is visible. Check your computer's network activity coming from your chatting application and you'll be able to find it.
