If your internet is slow and you are not sure if someone else could be on it then you can use this app to find out

Not only could this slow you down, but you do not want someone snooping around and accessing your files or infecting you with malware.

Windows users can download a free, portable program called Wireless Network Watcher (scroll down to the Zip download link below “Feedback” to get it), and Mac users can download a free, slightly more complex program called Who Is On My WiFi from the Mac App Store. Both tools will provide a list of every device currently connected to your network, so you can identify the ones that belong to you.

To use Wireless Network Watcher, just launch the program, and it will immediately begin scanning your network. This will take a minute or two—you’ll know it’s working if the bottom-left corner reads “Scanning…” Once it’s done, that message will disappear, and you’ll be presented with a full list of connected devices.

The resulting list may look a little cryptic, especially if you aren’t super tech-savvy, but don’t worry. You can ignore the IP address and MAC address listings for now. If you’re using Wireless Network Watcher, just focus on the “Device Name” and “Network Adapter Company” columns.

To use Who’s On My WiFi, launch the program and choose “Yes, set up continuous automatic scanning” from the popup. Click Proceed on the next window, and the app will begin scanning your network for devices. You’ll see the “Scanning” message in the upper-right-hand corner when it’s working, so just give it a minute to do its thing.
