How to Check Which Devices Are Connected to Your Wi-Fi

Most people only think about who is on their Wi-Fi when something feels wrong: a film buffers for no clear reason, the connection slows down every evening, or a data allowance disappears faster than expected. In many cases the explanation is sitting quietly in your router’s device list, a phone you forgot, a TV updating itself, a neighbour who still has your old password, or occasionally a device nobody in the house recognises.

Checking which devices are connected to your Wi-Fi is not difficult, and you do not need any special training to do it. Your router already keeps a live list of everything using the network. This guide shows you how to find that list on a computer, on a phone, and through common router apps, how to tell your own devices apart from strangers, and what to do if you spot something that should not be there.

What Your Router’s Device List Actually Shows

Every device that joins your network gets a local IP address, usually something like 192.168.0.12 or 192.168.1.105, handed out automatically by the router’s DHCP service. Alongside that address, the router records the device’s MAC address, a hardware identifier such as 3C:7A:9F, and often a hostname like Sarahs-iPhone, Living-Room-TV, or something unhelpful like android-8f42.

The list normally shows both wired and wireless connections, and it may split them by band, so you can see which devices are on 2.4GHz and which are on 5GHz. Some routers also show how long a device has been connected and how much data it has used. That extra detail is gold when you are investigating: a device using gigabytes overnight is very different from one that has sent almost nothing.

One warning before you panic at the size of the list: modern homes have more connected devices than most people realise. Phones, laptops, TVs, streaming sticks, consoles, smart speakers, bulbs, plugs, doorbells, and printers all count. A list of 25 devices in a family home is not unusual.

Method 1: Check Through the Router Admin Page

The admin page gives the most complete and reliable list, because it comes straight from the router itself.

1. Connect to your home network. Use a laptop or phone that is already on your Wi-Fi, or plug a computer into the router with an Ethernet cable.
2. Find the router’s address. On Windows, open Command Prompt and type ipconfig, then look for Default Gateway. On a Mac, open System Settings, go to Wi-Fi, and check the details of your network. Common addresses are 192.168.0.1, 192.168.1.1, and 192.168.1.254.
3. Log in. Type that address into your browser and sign in with the router’s admin username and password. These are not always the same as the Wi-Fi password; they are often printed on a sticker on the router if you have never changed them.
4. Open the device list. The exact menu name varies. On TP-Link routers look for Advanced, then System Tools, then Statistics, or check DHCP Clients List. On Netgear, look for Attached Devices. On many ISP routers it is simply Connected Devices, My Network, or Devices on the home page.
5. Note anything you cannot identify. Write down its MAC address, IP address, and hostname before you change anything.

If you have never logged in before, take your time and explore the menus without changing anything. Getting comfortable with the admin page will make future jobs, from password changes to firmware updates, much less stressful.

Method 2: Use Your Router’s Phone App

Most modern routers and mesh systems are managed from an app instead of a web page. TP-Link uses Tether or Deco, Netgear uses Nighthawk or Orbi, Google uses Google Home, and many broadband providers have their own app tied to your account.

The steps are usually simpler than the web version. Open the app, sign in, tap your network, and look for Clients, Devices, or Connected Devices. Apps present the information in a friendlier way, with icons for phones, TVs, and computers, and some let you rename a device so it appears as Kitchen Speaker instead of a string of numbers. Many can also notify you when a new device joins, an easy security habit to switch on.

The trade-off is detail. Some apps hide MAC addresses, so for a serious investigation the web admin page is still the better tool.

Method 3: Check From Windows or With a Network Scanner

If you cannot get into the router, a scanner on your own computer can give you a good second opinion. On Windows, the ipconfig command confirms your own address and gateway, and the command arp -a shows other devices your computer has recently talked to on the local network. It is not a complete list, but it is a quick sanity check. Microsoft explains these networking commands in its official guide to fixing Wi-Fi connection problems in Windows, which is also useful when a device shows as connected but has no internet.

Free scanner apps for phones do a similar job by pinging every address on your network and listing what answers. They are handy, but treat their device labels with caution: a scanner guesses brands from MAC address prefixes, and it can be wrong. Always confirm a suspicious device in the router’s own list before acting.

How to Tell Your Devices From a Stranger’s

This is the part people skip, and it is where most false alarms happen. Work through it methodically:

• Count and name your own devices first. Walk room to room and list everything with Wi-Fi, including the easy-to-forget items: the printer, the TV box, the smart meter display, a child’s tablet, and the work laptop in a bag.
• Match MAC addresses. On an iPhone, check Settings, General, About, Wi-Fi Address. On Android, check Settings, About Phone, Status. On Windows, ipconfig /all shows the Physical Address. Compare these with the router list.
• Turn things off and watch the list. Switch off a doubtful device, wait a minute, and refresh the router page. If the entry goes offline, you have identified it.
• Watch out for randomised MAC addresses. Modern phones use a private or randomised Wi-Fi address per network, so the same phone may appear with an address that does not match the one printed in its settings for other networks. This feature, explained in Google’s Android help pages on Wi-Fi MAC randomisation, is good for privacy but can make one phone look like a mystery device.
• Check the data usage and connection time. A neighbour streaming films leaves a very different footprint from a smart plug that sends a few kilobytes a day.

What to Do If You Find an Unknown Device

If, after checking properly, a device still makes no sense, treat it as a security problem and act the same day. Change the Wi-Fi password to a long, unique one using WPA2 or WPA3 security, which will disconnect every device, including the intruder. Reconnect only your own devices. Then change the router’s admin password too, because anyone who guessed one password might try the other. Finally, check for firmware updates in the admin page and install them.

Once the password is changed, blocking becomes much easier to manage. The natural next step is learning how to block a specific device from your Wi-Fi network using the deny list and MAC filtering tools covered in our companion guide.

Common Mistakes and Useful Tips

• Panicking over the guest and offline lists. Many routers show previously connected devices as well as live ones. Check whether the list says online, active, or connected before worrying.
• Forgetting wired devices. A desktop, TV, or console on a cable still appears in the list and still counts as a connected device.
• Naming nothing. Rename devices in the app or admin page as you identify them. Ten minutes of labelling today saves an hour of detective work later.
• Checking once and never again. Make it a monthly habit, or turn on new-device notifications and let the router do the watching for you.
• Sharing the new password widely. After a clean-up, give the password only to people who need it, and use a guest network for visitors.

Conclusion

Your router already knows exactly what is using your Wi-Fi; you just need to look. Whether you use the admin page at 192.168.0.1, the manufacturer’s app, or a quick scan from your computer, five minutes of checking tells you whether your network is clean or crowded with freeloaders. Identify each device calmly, label what you own, and if a genuine stranger appears, change the password, update the firmware, and reconnect only the devices you trust. Do that a few times a year and your network will stay yours.

Frequently Asked Questions

Can I see who is on my Wi-Fi without logging in to the router?

You can get a partial view with a network scanner app or the arp command on a computer, but only the router shows the complete, authoritative list, including which band each device uses and how much data it has consumed.

Why does my router show more devices than I own?

Usually because of forgotten smart devices, wired equipment, and phones using randomised MAC addresses. Some routers also keep recently disconnected devices visible for a while. Work through your home room by room before assuming anything is wrong.

Can I kick a device off my Wi-Fi from the device list?

Many apps and admin pages have a block, pause, or deny option next to each device. On routers without one, changing the Wi-Fi password disconnects everything at once, and only people with the new password can rejoin.

How often should I check my connected devices?

Once a month is a good habit, and immediately whenever your connection slows down unexpectedly or your data use spikes. If your router supports new-device alerts, enable them and you will not need to remember.

Does a device on my network mean my data has been stolen?

Not automatically. An unknown device might be a neighbour using an old shared password just for browsing. It is still a risk worth removing, because anyone on your network is inside your home’s digital front door.
