How to See Who's Connected to Your Wi-Fi on Your Phone: A Step-by-Step Guide

Have you noticed your internet has slowed down, and your data usage is unusually high? Perhaps unauthorized devices have connected to your Wi-Fi network—neighbors, guests who forgot to disconnect, or even hackers. Checking the list of connected devices from your phone is the first step to securing your network.

In this article you will find 5 working methodsHow to check who is using your Wi-Fi using just your smartphone Android or iOSWe'll explore built-in router tools, mobile apps, and even hidden operating system features. No computer or complicated setup required—it's all done in 2-3 minutes!

Important: If you detect unknown devices, don't panic. There are instructions at the end of the article on how to do this. block other people's gadgets and protect your network from repeated connections. We'll also explain how to distinguish legitimate devices (such as smart light bulbs or TVs) from potential "sprays."

1. Checking via the router's web interface from your phone

The most reliable way is to log in router control panel via a browser on a smartphone. This method works for any brands of routers: TP-Link, ASUS, Keenetic, D-Link, Zyxel and others. You'll only need the login and password for the admin panel (usually found on a sticker on the router body).

Instructions:

• 📶 Connect your phone to your Wi-Fi (if already connected, skip this step).
• 🌐 Open your browser (Chrome, Safari, Firefox) and enter in the address bar 192.168.0.1 or 192.168.1.1If it doesn't work, try 192.168.8.1 (For TP-Link) or my.keenetic.net (For Keenetic).
• 🔑 Enter your login and password (by default it is often admin/admin or admin/empty).
• 🔍 Find the section with connected devices. It's usually called:
  • TP-Link: Wireless → Wireless Statistics or DHCP → DHCP Clients List
  • ASUS: Network map or Local Network → Client List
  • Keenetic: Devices (in the main menu)

In the list you will see all the devices with their MAC addresses, IP addresses and names (if assigned). Unknown gadgets can be identified by manufacturer - the first 6 characters of the MAC address indicate the brand (for example, 00:1A:79 — Samsung, 3C:5A:B4 — Google).

⚠️ Attention: If you have never changed the password for the router admin panel, do so immediately after checking. Standard combinations (admin/admin) are known to hackers and allow them to gain complete control over your network.

2. Using mobile applications for network analysis

If accessing your router settings is inconvenient, you can use specialized apps. They scan the network and display all connected devices, sometimes even indicating the device model. The best options are:

Example of working with Fing:

1. Download the app from App Store or Google Play.
2. Connect your phone to your Wi-Fi.
3. Run a scan and the app will show all devices on the network.
4. Click on an unknown device to see its MAC address and manufacturer.

Important: Applications do not show devices connected via cable (Ethernet) unless they are active on the local network. For a complete analysis, it is better to combine this method with checking through a router.

Check the MAC address by searching on Google (e.g. "MAC 00:1A:79")

Compare with your list of gadgets (TV, printer, smart bulbs)

Try disabling it temporarily through the router (section "Parent Control" or "Blocking")

Change your Wi-Fi password if your device is unrecognized-->

3. How to identify "friend" and "foe" devices on the network

Not all unknown devices on the list are hackers or neighbors. Users often forget about connected gadgets:

• 📺 Smart TVs (Samsung Smart TV, LG WebOS, Android TV)
• 💡 Smart Home: light bulbs (Xiaomi Yeelight), sockets (TP-Link Tapo), thermostats
• 🎮 Game consoles (PlayStation, Xbox, Nintendo Switch)
• 🖨️ Printers and MFPs with Wi-Fi Direct support
• 📱 Old phones, which have not been used for a long time, but remain online

How to identify your devices:

1. Check MAC addresses: they are usually indicated on the stickers of the gadgets or in their settings (for example, in Settings → About phone → Status on Android).
2. Use the device name: Many routers allow you to assign user-friendly names to devices (for example, "TV_room").
3. Disable suspicious gadgets one by one and check if the device disappears from the list.

If the device is not recognized, but does not interfere with the network, you can leave it under observation. However, if it consumes a lot of traffic (this is visible in some routers or applications like Fing), it is better to block it.

How do hackers disguise their devices?

Some Wi-Fi hacking programs allow you to spoof MAC addresses, mimicking devices from popular brands (such as iPhones or Samsung). If a "second" device with the same MAC address appears on the network, this is a sure sign of an attack. In this case, you should immediately change your Wi-Fi password and the router's admin panel password.

4. Checking via Android settings (without third-party apps)

On phones with Android 10 and newer versions have a hidden feature that displays a list of devices on the local network. It doesn't provide as much information as dedicated apps, but it can be helpful in emergency situations.

Instructions:

1. Open Settings → Network & Internet → Wi-Fi.
2. Tap on the name of your network (the one you are connected to).
3. Scroll down and find the section Devices on the network or Local devices (may be absent on some firmware versions).
4. Android will display a list of devices with their IP addresses. Unfortunately, MAC addresses are not displayed here.

This method does not work on all phones. For example, on Samsung Galaxy with shell One UI the section may be called Device management, and on Xiaomi (MIUI) it's not there at all. If you can't find it, try other methods.

5. Traffic analysis: who is "eating" your internet?

If the goal is not just to find out who is connected, but to identify "parasite"If you're using a device that's slowing down your network, you need to analyze your traffic consumption. This can be done:

• 📊 Via a router: many models (ASUS, Keenetic) show traffic statistics by device in the section Traffic Monitor or Statistics.
• 📱 Through applications: GlassWire (Android/iOS) or NetGuard (Android only) tracks which devices are active and how much data they consume.
• 🖥️ Via computer: programs Wireshark or Microsoft Network Monitor (for experienced users).

Signs of a "parasite":

• The device consumes traffic even at night when everyone is sleeping.
• The MAC address belongs to an unknown manufacturer (checked through services like MAC Vendors).
• The router statistics show connections to suspicious IP addresses (for example, in other countries).

If you have found such a device, block him immediately through the router settings (section Parent Control, Access Control or Blacklist).

⚠️ AttentionSome smart devices (such as CCTV cameras) can transmit data to cloud servers 24/7. Before blocking a gadget, make sure it's not yours.

6. How to block other people's devices and protect Wi-Fi

Finding the "parasite" is half the battle. Now we need to block him And protect the network from repeated connections. Here's a checklist of actions:

Change your Wi-Fi password to a complex one (at least 12 characters, with numbers and special characters)

Disable the WPS function (it is vulnerable to hacking)

Enable MAC address filtering (Wireless MAC Filter section)

Update your router firmware to the latest version

Change the password for the router admin panel (do not leave it as admin/admin) -->

More details about each point:

1. Changing your Wi-Fi password:
   • Go to your router settings (see Section 1).
   • Find the section Wireless → Wireless Security (or Wireless Network → Security).
   • Select encryption type WPA2-PSK or WPA3-PSK (don't use outdated WEP!).
   • Create a strong password. Example: K7#pL9!vR2$qM1.

Disabling WPS:

Function WPS (Wi-Fi Protected Setup) allows you to connect to the network using a PIN code that is easy to guess. Disable it in the section Wireless → WPS or Wireless Network → WPS.

MAC address filtering:

Whitelist only the MAC addresses of your devices. This won't provide 100% protection (MACs can be spoofed), but it will make it harder for hackers. The setting is in Wireless → MAC Filter.

After the changes reboot the router and reconnect all your devices. If anyone was trying to use your Wi-Fi, they will be disconnected.

7. Common Mistakes and Myths About Wi-Fi Testing

When diagnosing a network, users often encounter false positives or incorrect conclusions. Let's look at the most common errors:

Another common myth: "My neighbors can't connect to my Wi-Fi because the signal is weak."In fact, even with a weak signal, an experienced user can use directional antennas or amplifiers to pick up your network. Password protection and encryption — is the only reliable way.

FAQ: Answers to Frequently Asked Questions

Is it possible to find out who is connected to Wi-Fi if I'm not the network admin (for example, in an office or cafe)?

No. Only the network administrator can view the list of connected devices through the router settings. Apps like Fing will only show devices in your local subnet, but will not provide information about other users of the shared network.

I found an unknown device with a MAC address 00:1A:79:...How do you know whose gadget it is?

The first 6 characters of the MAC address (in your case 00:1A:79) indicate the manufacturer. Check them through the service MAC Vendors. For example, 00:1A:79 belongs SamsungIf it's not your gadget, block it.

Is it possible to track the physical location of a device connected to my Wi-Fi?

It is impossible to determine the exact location, but the distance can be roughly estimated:

1. In some routers (ASUS, Netgear) there is a function Signal Strength - it shows the signal level of the device.
2. Apps like WiFi Analyzer (Android) plots a signal strength graph. The closer the device is to the router, the higher the signal strength (for example, -30 dBm - near, -80 dBm - far).

However, this method only works for devices connected over the air (not via cable).

I changed my Wi-Fi password, but the unknown device reappeared. What should I do?

Possible reasons:

• The device is connected via WPS (disable this feature in your router).
• A hacker broke into the router's admin panel and reset the password. Change your admin panel password immediately. and update the firmware.
• You have it turned on Guest access with a separate password (check in the router settings).

If the problem persists, please do the following: resetting the router to factory settings (button Reset on the body) and configure it again.

Could my actions to block devices break the law?

No, if it is your personal networkYou have every right to manage connections to your router. However, if you're on a corporate or public network (such as an office or cafe), blocking devices without the administrator's consent may be considered a violation of internal rules.
