Nirsoft Wireless Network Watcher

Wireless Network Watcher doesn’t require you to install or add dll files at all. To start using Wireless Network Watcher, you just need to extract the WNetWatcher.exe executable file and run it.

If you wish, you can also download the WNetWatcher version with full installation support (wnetwatcher_setup.exe), with which you will have a Wireless Network Watcher program shortcut to be able to launch it from the Start menu.

After running WNetWatcher, it will automatically locate the wireless adapter and scan your local network. After a few seconds, you should be able to see the list of computers currently connected to the network.

If for some reason, WNetWatcher fails to scan and locate the network, you can try manually selecting the network adapter by pressing F9 (Advanced Options) and selecting the correct network to scan.

MAC Address : The MAC address of the network adapter.

Network Adapter Company : Manufacturer of network adapter. This column can help you detect the type of device or computer. For example, if the company name is Apple, this connected device could be Mac, iPhone or iPad.

By default, this utility uses the internal MAC address database stored inside the .exe file, but not always the latest MAC addresses. You can manually download the latest MAC address file from http://standards.ieee.org/develop/regauth/oui/oui.txt and then place the oui.txt file into the same directory as the file. WNetWatcher.exe. Then, if you run WNetWatcher , the program will automatically use the external oui.txt file instead of the internal MAC address database.

Device Information : This column displays ‘Your Computer’ if the device is the computer you are using. The column will show ‘Your Router’ if the device is a wireless router.

User Text : You can assign a text content to any device detected by WNetWatcher. By default, this field displays the name of the device. To change User Text, just double click on it and type the desired text.
