Find out who is using your wireless network

Do you suspect that someone is wrongfully using your wireless network connection? Maybe your wireless connection is slow these days and you suspect that someone has hacked into it. Well, there are several free tools available which can help you detect who is using your connection illegally. I am covering two tools here, but if you know of any more, please do share below in the comments.

Wireless Network Watcher is the 3rd new tool released by Nirsoft, this month. It is a small utility that scans your wireless network and displays the list of all computers and devices that are currently connected to your network.

It will display the following information for each connection:

1. IP address
2. MAC address
3. Manufacturer of the network card
4. Computer name
5. Device Name.

The tool also allows you to export the list of connected devices and save it as an html,xml, csv or a text file.
Another utility for sniffing if someone else is using your wireless network is Zamzom.

Zamzom Wireless Network Tool lets you see all  the users that are using your wireless network. There are two scan options but only the Fast Scan is available in the free version, but that should be good enough for most, I suppose. Once the scan is completed, it displays the IP address and MAC address.
