Do you feel that your high speed connection is bogged down, and you are getting a creepy feeling that someone’s stealing your bandwidth on your Wi-Fi network.
Wireless network connections have become popular in past years, thanks to an increasing number of devices that utilize wireless connections. But there is a problem associated with it, or more precisely with the securing of wireless routers and devices to block unauthorized access: The device needs to use proper encryption to block third parties from accessing it. Many users do not know the differences between WEP or WPA encryption, or which of the encryption schemes they should select for best security.
That could leave their wireless routers open for unauthorized access, especially if no encryption or weak encryption is configured.
The best option here is to use the strongest encryption possible. That however may not be always possible, if devices that need to connect to the wi-fi router do not support that.
However even after taking all precautionary measures to prevent unauthorized access one can’t guarantee their wireless network will be safe. Here are some cool apps which lets you to detect all computer names, Mac and IP addresses using your wireless network.
Wireless Network Watcher is a small utility from Nirsoft that scans your wireless network and displays the list of all computers and devices that are currently connected to your network. For every computer or device that is connected to your network, the software provides the IP address, MAC address, the company that manufactured the network card, and optionally the computer name.
You can also export the connected devices list into html/xml/csv/text file, or copy the list to the clipboard and then paste into Excel or other spreadsheet application.
There is an option to make Wireless Network Watcher periodically perform background scans to see if any new devices have joined the network. If new devices are found the software will sound a short beep to alert the user.
This is another free application that scans your WiFi network at regular intervals pinging IP addresses for replies. If a connected device is found the programs alerts the user of the intruder. If the device is known to you, there is an option to mark it so. This way the program won’t alert you when it finds the device in future.
SoftPerfect WiFi Guard provides less information than Wireless Network Watcher about connected devices but is enough for most purposes.
