neighbors using my WI-fi?

Question

i think my nieghboor is using my wi fi how can i tell

Answer 1

check your router to see what DHCP addresses have been handed out. If it's more that the number of computer you have then someone is using it.

While you are in there secure it....

Answer 2

You can just secure your wireless connection.
Your access point / wireless router should come with simple instructions to set up security, and if you've lost the papers it came with, the manufacturer's website will have instructions.

If you get a choice, set up WPA, if it doesn't have that, set up WEP or mac address filtering. If it doesn't have that, password protect it for the moment, then go out, and buy a new one.

While using other people's bandwidth could get you sued, it's still exceptionally common. Actually, some trusting people leave their wireless access open to be friendly. There are whole neighborhoods in New York where you can wander happily with a laptop. (If you're interested in doing that, please post a question about setting up security and allowing guest wireless access.)

Answer 3

Your wireless router setup usually has a sections showing connections. Most common connection in a browser are http://192.168.1.1 or http://192.168.0.1 (check your documentation.
If you have not secured your router and you have computing neighbors, you are probably sharing your Internet connection. They may not even know they are using yours. An Internet search will reveal many articles on securing a wireless network.
Finally, your computer must have security software loaded--firewall, antivirus, and antispyware. If someone connects to your wireless network, he is networked with your computer inside of the router firewall! As a computer tech, 90% of my work is cleaning or reloading unsecured computers.

Answer 4

Simple. Check the recently used IPs, and to check the ones you have go to Start, Run, type in ipconfig. This will tell you yours. If the ones you've used appear with others you havent on the list, then someone else did. In this case change the encryption on your network. Refer to router manual for all the IP lists and encryption changing.

Answer 5

This problem is in your PC?? o in your Internet Connection?? You can enter on your rooter and search that! (in the case that your question was "Internet Connection"), your router can tell you all the PCs (for LAN and wireless connection) that are connected at your LAN and Internet Connection. In this case only put a password (if you have now a password, change it! and put a bestial password! more that 20 digits, OK? this will put end to your problem).

But if the problem is in your PC (you think that the people connected at your PC via wireless), your card PCMCIA (in laptop), PCI (PC normal), or integrated wireless (in laptop too), you can go START/control panel/red connexions and change options in your WIRELESS CONNECTION (password, etc.), and go to "My places of red or My Network Places??" I don't now exactly the names in English windows, and click "see all workgrops" OK? and look other computers, if appear PCs that you haven't, you have there to your "neighbor", but this is a possibility of hundreds them! OK?? investigate these things a more, OK??

Luck!!
