A nifty tool to check who’s using your network

It’s not uncommon to find that a lot of people are using your Wi-Fi network without your permission. Just because it isn’t uncommon doesn’t mean it’s not frustrating to have to share your Wi-Fi. With that said, it’s important to make sure that you’re keeping a close eye on who’s using your Wi-Fi. Even if you’re not trying to weed out Wi-Fi leeches, knowing who’s using your Wi-Fi can help you keep track of Internet speeds and data usage. Who Is On My Wifi by IO3O LLC is a utility tool that lets you check who’s using your Wi-Fi.

The Positives

This program has one job, and it does perform its purpose well. Installing the software was a painless process, so once you download the installer file and run the program, you’ll be able to use it immediately. Typically, you’ll be taken to a Wizard mode where the program will walk you through the process of using the program. 

Finding out who is on your Wi-Fi is an easy process. All you have to do is click scan now and Who Is On My Wi-Fi will scan your network for all of the devices connected. The scan takes a few minutes, but the list of results the program gets is quite comprehensive so it’s worth the wait.

The program also possesses a lot of features that users will appreciate. One such feature is being able to schedule scans. Who Is On My Wi-Fi automatically scans your network every few minutes. You can also set the frequency of these scans. You can choose to set the program to scan every 2 to 10 minutes. This is great because it allows you to check your network frequently and without having to go through a lot of trouble.

The Negatives

Probably the biggest issue with this program is the fact that the design isn’t very good. It has a dark blue and white color scheme. While that in itself isn’t bad, what’s really painful to the eye is the bright yellow highlight that they chose to use for the devices after you scan your network. Additionally, it’s a bit annoying to have to manually change the networks from UNKNOWN to KNOWN. Finally, the fact that notifications have both a Windows pop-up and a voice notification is unnecessary and frustration. All that said, none of these things are terrible enough that it would shy users away from the program. It’s still perfectly acceptable.

Good at What It Does

Who Is On My Wifi’s purpose is to help users find out who is using their Wi-Fi and it certainly performs its duties well with speed and efficiency. The design of the software could have been a little better. However, it is ultimately not terrible enough to be a deal breaker. The useful features that the program possesses more than makes up for the unfortunate design choices. If you want to keep an eye on who’s using your Wi-Fi network, go ahead and use this program. It definitely won’t let you down.
