The Devices Quietly Connected to Your Wi-Fi

Your home Wi-Fi may have more guests than you realise. Phones, tablets, and laptops are obvious, but televisions, printers, streaming boxes, smart speakers, and other connected gadgets can remain on the network long after you have forgotten about them.
Most routers have a way to view connected devices, either through an app, a web interface, or information provided by your internet service provider. The exact process varies, but the list can be surprisingly revealing.
You might recognise everything immediately. Then again, you may see an old tablet, a television you no longer own, or a device with a name that tells you absolutely nothing.
Do not panic when you see an unfamiliar name. Some devices identify themselves using technical names or model numbers rather than something obvious like “Mike’s TV.” Before disconnecting anything, look at the device list alongside the equipment you actually have at home.
Old devices are particularly worth noticing. If you gave away a phone, sold a streaming box, or replaced a printer, make sure the old device is no longer connected to your network. Ideally, it should also have been removed from your accounts before you passed it on.
If you discover a device you genuinely cannot identify, change your Wi-Fi password and reconnect only the equipment you recognise. This is more disruptive because you will need to reconnect your household devices, but it gives you a clean starting point.
While you are there, look at the router’s administrator settings too. The password used to manage the router is different from the Wi-Fi password, and it should not be left at an easily guessed default.
You do not need to become an expert in home networking. Think of it like looking through the list of people who have keys to your house. Most will be perfectly legitimate, but it is useful to know who is still there.
Once or twice a year, spend a few minutes reviewing the connected-device list. Your home network should reflect the devices you actually use, not every gadget that has passed through your front door over the years.
