Which device is this?
Our check or the Windows app may show a number like 192.168.1.20. Here is how to work out what it is.
The numbers are the device's address on your home network. Here are three easy ways to find out which gadget it is.
1. Look at your router's list
Sign in to your router and look for a list called Connected Devices, Attached Devices, Client List or DHCP Clients. It usually shows each device's name and address. Find the address from our report. In a phone app such as eero or Google Home, look at the list of devices.
2. Use the unplug test
Unplug or switch off the device you suspect, wait a minute, and run the check again (or the Windows app). If the warning is gone, you found it.
3. Look at the device's own settings
Cameras, TVs and printers often show their address in their settings or in their phone app, under Network or About.
What the names mean
- A name with a brand in it (like Samsung or Roku) is usually a TV or streaming box.
- Names that are only letters and numbers can be a camera, a printer, a smart plug or a phone.
- If you truly cannot place it, ask someone you trust to look at your router's list with you.
Not comfortable doing this? That is okay.
You do not have to do this alone. You can ask a family member, call your internet company, or take your router to a local computer repair shop. Take your time and ask for help instead of guessing.
