Spot unknown devices on your WiFi network
Who Is On My Wifi is a focused Windows utility for checking which devices are connected to your wireless network. Its main appeal is simple: if you suspect neighbors, guests, or forgotten devices are using your connection, it gives you a clearer view of what is currently on the network.
The basic workflow is straightforward. Open the program, use the guided mode if needed, and start a network scan. After a few minutes, it returns a fairly detailed list of connected devices. This makes it useful not only for spotting possible intruders, but also for keeping track of phones, laptops, smart TVs, and other household hardware that may be affecting bandwidth or data use.
One of its better everyday features is scheduled scanning. Instead of checking manually every time, you can set the software to rescan at regular intervals, from every 2 to 10 minutes. There is also an event log, which helps you review activity over time rather than relying only on a single scan result. For users who want ongoing awareness without constantly watching their router settings, this is a practical touch.
That said, the software is not as friendly as it could be. The interface looks dated, with a color scheme that can be distracting, and some parts of the layout are not especially intuitive. Devices may need to be manually changed from unknown to known, which adds extra work during setup. Notifications can also feel excessive because they may combine Windows pop-ups with voice alerts. The lack of help files makes the rougher parts of the interface more noticeable.
Overall, Who Is On My Wifi is best for users who want a dedicated tool for monitoring connected devices and do not mind a plain, slightly awkward interface. It does its core job well, but it is more practical than polished.
