How to Check Who's Connected to My Wi-Fi Router Online: 7 Working Methods

Have you noticed your internet has slowed down and your data usage is depleting faster than usual? Perhaps unauthorized devices have connected to your Wi-Fi—neighbors, guests who forgot to disconnect, or even hackers. Checking connected devices Accessing your router online takes just a few minutes, but it helps identify and block unwanted devices. In this article, we'll cover all the current methods—from standard router tools to specialized apps and commands for advanced users.

You don't have to be an IT specialist to figure this out. Most modern routers (TP-Link, ASUS, Keenetic, MikroTik and others) provide user-friendly web interfaces where a list of connected devices is displayed in real time. And if you don't have access to the control panel, mobile application or even Windows/Linux command lineThe main thing is to know where to look and what to pay attention to.

It is important not only to detect “outsiders”, but also to understand how they connected: through a vulnerability in the password, a function WPS, or someone just peeked at yours Wi-Fi keyAt the end of the article we will give recommendations on how Permanently block access to outsiders and protect the network from repeated intrusions.

1. Checking via the router's web interface (the most reliable method)

Every router has a built-in control panel accessible through a browser. Here you can see a complete list of devices connected to your network—both wired and wireless.Ethernet), and by Wi-FiThe instructions are universal for most models, but we will point out some nuances for popular brands.

To access settings:

1. Find out Router IP address. Usually it is 192.168.0.1 or 192.168.1.1You can check it via the command line:

   ipconfig (for Windows)
   ifconfig (for Linux/Mac)

   Look for the line Main gateway (Default Gateway).

2. Enter this address into the address bar of your browser (for example, http://192.168.0.1).
3. Enter your login and password. By default, this is often admin/admin or admin/emptyIf it doesn't fit, check the sticker on the back of the router.

The further path depends on the model:

• 🔹 TP-Link: Go to Wireless Mode → Wireless Mode Statistics or DHCP → DHCP Client List.
• 🔹 ASUS: Open Network map - all devices are displayed here with the indication IP, MAC addresses and name.
• 🔹 Keenetic: Chapter Devices in the main menu. You can even see your connection history here.
• 🔹 MikroTik: IN IP → DHCP Server → Leases or Wireless → Registration Table.

In some routers (for example, Xiaomi or Tenda) The list of devices is not updated in real time, but with a delay of 1-2 minutes. If you suspect that someone has just connected, refresh the page in F5.

2. Using mobile apps to monitor Wi-Fi

If you are too lazy to go into the router settings or don’t have access to a computer, you can use mobile applicationsThey scan the network and display all connected devices, sometimes even indicating their model. The main advantage is that you don't need to enter router passwords.

Top 3 verified apps:

• 📱 Fing (Android/iOS) - scans the network, shows IP, MAC, device name, and even open ports. There's a notification feature for new connections.
• 📱 WiFi Guard (Android) - compares current devices with a "white list" and signals about unknown gadgets.
• 📱 NetScan (iOS) - a simple scanner with the ability to export a list of devices.

How to use (using example) Fing):

1. Connect to your Wi-Fi network.
2. Launch the app and click Scan.
3. In 10-20 seconds, you will see a list of devices. Click on any of them to learn more (manufacturer, MAC, IP).
4. Unknown devices can be blocked directly from the app (if your router supports this feature).

Try disabling it through the router control panel|

Change your Wi-Fi password if you suspect hacking-->

Please note: Some applications (eg. WiFi Guard) require root rights on Android to block devices. Without them, they'll only show a list but won't be able to block anything.

Why might apps show "extra" devices?

Sometimes the list shows gadgets that have already been disabled, but they IP address hasn't been released yet (DHCP lease). Devices from neighboring networks may also appear if they use the same Wi-Fi channel. To avoid false positives, refresh the scan 2-3 times at one-minute intervals.

3. Checking via the command line (for Windows, Linux, Mac)

If you prefer to work without a graphical interface, you can use command lineThis method is suitable for all operating systems and does not require the installation of additional software.

For Windows:

1. Open Command line (Win + R → enter cmd → Enter).
2. Enter the command:

   arp -a

   You will see a table with IP And MAC addresses all devices on the local network.

3. To filter only active connections, use:

   arp -a | findstr "dynamic"

For Linux/Mac:

1. Open Terminal.
2. Enter:

   nmap -sn 192.168.0.0/24

   (replace 192.168.0.0 to your subnet, if it is different).

3. For detailed scanning (indicating device models):

   sudo nmap -O 192.168.0.0/24

Scan results can be saved to a file for further analysis:

arp -a > wifi_devices.txt  (Windows)
nmap -sn 192.168.0.0/24 > wifi_scan.txt  (Linux/Mac)

4. How to distinguish your device from someone else's: MAC address analysis

In the list of connected devices you will see MAC addresses — unique identifiers for each gadget. These can be used to identify the device's owner, even if it hides its name. Here's how:

Every MAC address consists of 6 pairs of characters (for example, 00:1A:79:4F:2B:1C). The first 3 pairs (00:1A:79) indicate the manufacturer. You can check them using special services:

• 🌍 MAC Vendor Lookup (https://macvendors.com) - enter MAC and recognize the brand (Apple, Samsung, Xiaomi, etc.).
• 🌍 Wireshark OUI Lookup (https://www.wireshark.org/tools/oui-lookup.html) - a more detailed base.
• 🌍 Arul John (https://aruljohn.com/mac.pl) - shows not only the brand, but also the model of the device (if known).

Examples of transcription:

If you see a device with MAC address from Apple, but you don't have equipment from this brand—that's a reason to be wary. The same applies to unknown manufacturers like Shenzhen Bilian or TP-Link Technologies (if you don't have devices of this brand).

5. Online services for remote Wi-Fi testing (with caveats)

You can find services online that promise to show connected devices "online" without access to the router. For example, Who Is On My WiFi or Advanced IP ScannerHowever, there are important nuances here:

Advantages of online services:

• 🔍 No need to install programs.
• 🔍 Quick scan (1–2 minutes).
• 🔍 Some services show the geolocation of devices (albeit with a large margin of error).

Disadvantages and risks:

• ⚠️ Most services require installation of their software. (which may be unsafe).
• ⚠️ They only scan your local network, not your router directly, so they may miss devices.
• ⚠️ Which websites collect data about your network (it’s better to use offline tools).

If you still want to give it a try, here are some relatively safe options:

• 🖥️ Advanced IP Scanner (installed on PC, but does not require registration).
• 🖥️ Angry IP Scanner (open source, no spyware).
• 🖥️ LANScan (for Mac).

Why do online services often lie?

They scan the network from your computer, not from the router. If a device is connected to Wi-Fi but not active (for example, a smartphone in sleep mode), the service won't see it. They also don't show devices connected via cable (Ethernet), if your PC is not in the same subnet.

6. How to block other people's devices: step-by-step instructions

If you find unfamiliar devices on the network, you need to disable and blockHere's how to do it:

Method 1: Through the router control panel (most reliable)

1. Go to the router's web interface (see Section 1).
2. Find the section with devices (for example, DHCP → Client List or Wireless Mode → Statistics).
3. Select an unknown device and click Block or Disable.
4. In some routers (ASUS, Keenetic) can be added MAC address blacklisted (MAC Filter).

Method 2: Change your Wi-Fi password

If you suspect that someone has learned your password, change it:

1. Go to your router settings → Wireless mode (or Wi-Fi).
2. In the field Password (Password, Key) enter a new key (at least 12 characters, with numbers and special characters).
3. Save the settings. All devices will be disconnected and will need to reconnect.

Method 3: Disabling WPS

Function WPS (Wi-Fi Protected Setup) allows you to connect to the network without a password—just press a button on the router. It's convenient, but unsafe:

• Go to your router settings → WPS.
• Disable the feature or install PBC mode V Disabled.

7. How to protect your Wi-Fi from future hacking

To prevent anyone from connecting to your network without permission, follow these guidelines:

1. Use a strong password

• 🔐 Length: 12+ characters.
• 🔐 Combination: uppercase and lowercase letters, numbers, special characters (!@#$%).
• 🔐 Do not use personal information (dates of birth, names).

2. Enable WPA3 encryption

Outdated WPA2 vulnerable to attacks like KRACKIn the router settings, select:

Wireless Mode → Security → Authentication Mode: WPA3-Personal

3. Disable remote router management

If there is an option in the settings Remote access (Remote Management) — turn it offThis will prevent hacking through vulnerabilities in the web interface.

4. Update your router firmware

Manufacturers regularly release updates that patch vulnerabilities. Check the latest version in the section System or Software update.

5. Create a guest network

If you have frequent guests, set up a separate network with limited access:

Wireless → Guest Network → Enable

This will protect the main network from outside connections.

FAQ: Frequently asked questions about Wi-Fi testing

Is it possible to check who is connected to my Wi-Fi if I'm not at home?

Yes, but for this you need:

1. Have access to the router control panel via the Internet (function Remote control must be enabled).
2. Use the mobile app from the router manufacturer (for example, TP-Link Tether or ASUS Router).

If none of this is configured, remote verification is not possible.

What to do if there are many unknown devices in the list MAC addresses?

Possible reasons:

• Smart devices (light bulbs, cameras, speakers) that you forgot.
• Neighbors using your Wi-Fi (especially if the network is open or the password is weak).
• Viruses on your devices that create "shadow" connections.

Recommendations:

1. Disconnect all your devices from Wi-Fi and see which ones are left.
2. Check it out MAC addresses through MAC Vendor Lookup.
3. Change your password and enable WPA3.

Can someone connect to my Wi-Fi if I use a hidden network (hidden SSID)?

Yes. Hiding the network name (SSID) does not protect against hacking - an experienced hacker can find it using a scanner (for example, Kismet or Airodump-ng). A hidden network only makes it more difficult for legitimate users to connect.

Better use it strong password And WPA3, rather than rely on concealment SSID.

How do I find out which device is consuming the most traffic?

Some routers (ASUS, Keenetic, MikroTik) show traffic statistics by device in the section Monitoring or TrafficIf there is no such function, use:

• 📊 GlassWire (Windows) - Shows traffic for each device on the network.
• 📊 NetCut (Android) - analyzes who is using the most network resources.

What's happened MAC spoofing and how to protect yourself from it?

MAC spoofing - this is a substitution MAC addresses devices to bypass the blocking. For example, a hacker can "spoof" MAC your smartphone and connect to the network.

Protection:

• Use static IP to MAC binding (in settings DHCP).
• Turn on WPA3 - it is more difficult to hack than WPA2.
• Change your Wi-Fi password periodically.
