Security alert: How to make sure unauthorized devices aren't on your Wi-Fi network

You keep your device’s operating systems updated. You’re using internet security software. You're pretty savvy about not falling for online scams.

Even so, malware and cybercriminals can still get through. Run this free check to see if your router has been hacked by criminals giving them open access to all your files, passwords, and more.

Your security arsenal includes a firewall. Here’s a free test to make sure that your firewall is blocking access to bad actors and bots.

How many devices are connected to your home’s wireless network? A handful? Dozens? As time goes on and you add new gadgets, it's easy to lose track of everything connected, or worse, notice things that don't belong.

Here’s how to determine what’s on your network and prune anything that shouldn’t be:

Get into your router’s admin page

This is a relatively simple way to get an idea of who's using your network. Bonus: It's free! Log into your router to see an up-to-date list of connected devices. Your computer has a unique IP address or Internet Protocol address.

To get started, you’ll need your computer’s IP address. Tap or click here to learn how to find it.

Then, type the IP address into your browser’s address bar. This will open your router menu. Log in with the custom username and password for your router or the default information if you never set one. Here are directions to find and change the password if you don’t know it.

Once you’re in, check for a list that says DHCP Client or Connected Devices. From there, you’ll see a list of devices currently using your network. If you spot something you don’t recognize, it’s time to take action.

Change your Wi-Fi password and reconnect only the devices you trust. It’s a pretty lengthy process, but one worth doing.

UTILITY LIST: Here are all the best free Windows utilities in one place.

Use Advanced IP Scanner
