PROPER INSTRUCTIONS

Check what devices are connected to your home network: proper instructions

Seeing the devices on your home network is useful when you have a new router, an unfamiliar device appears, or Wi-Fi is slow. The most reliable place to look is the router or mesh system’s own administration page: it sees devices connected by both Wi-Fi and Ethernet. A phone app can be convenient, but do not assume its list is complete unless it is the app supplied by your router or mesh manufacturer.

What you need

Do this from your own network. If you are renting, do not reset or reconfigure equipment that belongs to the landlord or internet provider without permission.

Method 1: use the router or mesh device list

  1. Connect your computer or phone to the home network you want to inspect. Turn off mobile data temporarily on a phone if it keeps switching away from weak Wi-Fi.
  2. Open a browser and visit the router’s local address. Common addresses are 192.168.0.1, 192.168.1.1, 10.0.0.1, and 192.168.1.254. The address may be printed on the router label, in its manual, or shown as “Router” or “Gateway” in your network settings.
  3. Sign in using the administrator credentials. If you have never changed them, check the router label or the provider’s setup material. Do not repeatedly guess: some routers temporarily block login attempts.
  4. Look for a section named Connected devices, Device list, Clients, Network map, DHCP leases, or similar. On a mesh system, select the main network rather than a guest network if the app has separate views.
  5. Record the useful columns: device name, connection type, IP address, MAC address, manufacturer, and last-seen time. An IP address such as 192.168.1.37 is temporary and can change; a MAC address is generally a better way to distinguish a particular network interface.
  6. Match the obvious entries first. Your phone, laptop, television, printer, games console, smart speaker and wired desktop may identify themselves clearly. A device with “Apple”, “Samsung”, “Espressif”, “Raspberry Pi”, or a network-card manufacturer may need more checking.
  7. Rename recognised devices in the router interface if it supports labels. Use names such as Kitchen speaker or Alex laptop Ethernet, not just the person’s name. Clear labels make later checks faster.
  8. Open the details for anything unknown. Note whether it is connected now, when it was last seen, which Wi-Fi band it uses, and whether it is on Ethernet. A device last seen months ago is different from one actively transferring data.

Method 2: identify an unknown entry safely

  1. Count the entries and compare them with your expected equipment. Remember that one physical device can have several entries: a phone may use a different private Wi-Fi MAC address on each network, and a mesh node has several radios.
  2. Turn off Wi-Fi on one known device, wait a minute, then refresh the router list. The matching entry should change to offline or disappear. Turn Wi-Fi back on and refresh again. Repeat for a few uncertain devices, one at a time.
  3. For a wired device, unplug its Ethernet cable briefly only if doing so will not interrupt important work, calls, security equipment, or storage. Refresh the list and observe which entry goes offline.
  4. Check the device’s own network settings for its Wi-Fi MAC address and compare it with the router entry. Modern phones often use a private address; look for the address assigned specifically to your home network, not the factory hardware address.
  5. If an entry has no recognisable name, use its MAC-address manufacturer only as a clue. It can identify a network-chip vendor rather than the product. Do not treat “unknown” as proof of an intruder.

Confirmation and follow-up

You have a dependable inventory when every active entry is either recognised, intentionally isolated on a guest network, or documented for further checking. Test your labelling by turning off Wi-Fi on one known device and confirming that the label you gave it changes state. Revisit the list after a day: battery-powered and sleeping devices may only appear intermittently.

If an active device remains genuinely unknown, first change the Wi-Fi password to a long unique passphrase and reconnect your own devices. Also change the router administrator password, disable remote administration unless you deliberately use it, install offered router firmware updates, and remove or block the unknown client if the router allows it. A password change is more reliable than blocking one MAC address, because MAC addresses can be changed and the entry might simply be misidentified.
