How to Find Out Who's Connected to My Wi-Fi: 7 Proven Methods

Have you noticed your internet has slowed down and your data usage is depleting faster than usual? Perhaps other devices have connected to your Wi-Fi. A hacked password, an accidental connection from neighbors, or forgotten guest devices—the causes can vary, but the result is the same: your network is being used by more than just you. In this article, we'll look at how to prevent this. check the list of connected devices to the router, identify unknown gadgets and block them.

Testing methods depend on the router model, operating system, and even the device firmware. We've compiled all the relevant methods—from standard web interface tools to specialized apps. You'll learn how to determine MAC address, the name of the device and even its manufacturer, as well as what to do if you find someone else's smartphone or laptop on the network.

Important: Some methods require access to your router settings. If you haven't changed the default login and password (usually admin/admin or admin/1234), they can be found on a sticker on the back of the device. If the data is lost, you will have to reset the router to factory settings.

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

The most reliable method is to access your router's control panel. The interface may vary depending on the manufacturer (TP-Link, ASUS, Keenetic, MikroTik etc.), but the general principle is the same. You will need:

• 🖥️ A computer, laptop, or smartphone connected to the same network
• 🔑 Login and password for entering the router settings
• 🌐 Browser (Chrome, Firefox, Safari)

Instructions:

1. Open your browser and enter your router's IP address in the address bar. This is usually 192.168.0.1 or 192.168.1.1You can find the address on the device sticker or via the command ipconfig (For Windows) / ifconfig (For macOS/Linux) in the terminal.
2. Enter your login and password (by default it is often admin/admin).
3. Find the section with a list of connected devices. It may be called:
   • DHCP Clients List (at TP-Link)
   • Connected Devices (at ASUS)
   • Client list or Devices (at Keenetic)
   • Wireless → Wireless Statistics (at MikroTik)

In the table you will see:

• 📱 Device name (if it is specified in the gadget settings)
• 🔢 MAC address (unique identifier, for example 00:1A:2B:3C:4D:5E)
• 📡 IP address (local, for example 192.168.0.103)
• ⏱️ Connection time

2. How to identify someone else's device in the list of connected devices

Even if you see a list of devices, it's not always easy to tell which ones are yours and which are not. Here's how to spot the "outsiders":

Method 1: Checking by MAC address

First 6 characters MAC addresses (For example, 00:1A:2B) indicate the device manufacturer. You can use services like MAC Vendor Lookup Or simply enter the address into a search engine. For example:

• 00:0A:95 — Apple
• 3C:5A:B4 — Google (pixels, nexuses)
• 78:31:C1 — Xiaomi
• 00:90:4C — EPSON (printers)

Method 2: Comparison with your gadgets

Make a list MAC addresses your devices:

• 📱 On Android: Settings → About phone → General information → Wi-Fi MAC address
• 🍎 On iPhone/iPad: Settings → General → About → Wi-Fi Address
• 💻 On Windows: run in command line ipconfig /all and find the line Physical address
• 🖥️ On macOS: System Preferences → Network → Advanced → Ethernet/Wi-Fi → Ethernet ID

How to find the MAC address of smart devices (TV, speakers, light bulbs)

It is usually indicated on a sticker on the back panel or in the instructions. For Samsung Smart TV you can go in Settings → Support → Contact Information. U Xiaomi (For example, Mi Box) - V Settings → About device → Status.

Method 3: Monitoring activity

Some routers show traffic For each device. If an unknown device is downloading gigabytes of data, this is a clear sign of an unauthorized connection. Keenetic, for example, there are graphs of traffic consumption in the section Devices → Statistics.

3. Wi-Fi network monitoring apps

If accessing your router settings is inconvenient, you can use specialized programs. They scan the network and display all connected devices directly on your smartphone or computer.

For Android and iOS:

• 📱 Fing — identifies devices, shows open ports and vulnerabilities. Free version available.
• 📱 NetScan — scans the network and saves connection history.
• 📱 WiFi Guard — sends notifications when new devices are connected.

For Windows/macOS:

• 💻 Wireless Network Watcher (from NirSoft) is a free utility without installation.
• 💻 Angry IP Scanner — scans IP addresses and shows MAC.
• 💻 Advanced IP Scanner — identifies the manufacturer by MAC address.

Example of work Fing:

1. Download the app from App Store or Google Play.
2. Connect to your Wi-Fi network.
3. Click Scan — after a few seconds, a list of devices with IP, MAC and manufacturer name will appear.
4. Unknown gadgets can be added to the blacklist directly in the app (if your router supports this feature).

Important: Some apps require root access on Android or administrator rights on Windows to function properly. Without these, they may not display MAC addresses.

4. How to block someone else's device in a router

If you detect a third-party device, there are several ways to block it. The most reliable is through the router settings.

Method 1: Blocking by MAC address

Most routers allow you to create blacklist (blacklist) or white list (whitelist) devices. Instructions for TP-Link:

1. Go to the web interface (192.168.0.1).
2. Go to Wireless → Wireless MAC Filtering.
3. Select Disable (blacklist) or Enable (white list).
4. Add MAC address someone else's device and save the settings.

Method 2: Change your Wi-Fi password

If there are a lot of unfamiliar devices or you are not sure which one is "your" one, it is easier change password from the network:

1. Find it in your router settings Wireless → Wireless Security.
2. Select encryption type WPA2-PSK (or WPA3, if supported).
3. Create a complex password (at least 12 characters, with numbers and special characters).
4. Save the changes - all devices will be disconnected and will need to reconnect.

Method 3: Disabling DHCP for a specific IP

You can bind it manually MAC address to a specific IP and prohibit the distribution of addresses to other devices:

1. Find it in your router DHCP → DHCP Reservation.
2. Add your devices with their MAC and assign IP to them.
3. Set a limit on the number of connected devices (if such a function is available).

5. Why are strangers connecting to your Wi-Fi?

The reasons can vary, from simple inattention to targeted hacking. Let's look at the most common ones:

1. Weak password

Passwords like 12345678, qwerty or password They can be cracked in seconds using specialized software. Passwords containing the following are also vulnerable:

• 📅 Dates of birth
• 👨‍👩‍👧‍👦 Family Members' Names
• 📍 Addresses or house numbers

2. Password leak

You might have accidentally:

• 📋 Write the password on a piece of paper that the guests see.
• 💬 Notify him by phone or messenger.
• 🔑 Enter on someone else's device (for example, when asked to "send a file").

3. Router vulnerabilities

Some router models have security holes, allowing you to connect without a password. For example:

• 🛠️ Outdated firmware (update in the section System Tools → Firmware Upgrade).
• 🔓 Enabled WPS (a technology that makes connection easier and easier to hack).
• 📡 Open guest network (if it is not password protected).

4. Neighbors with duplicate SSIDs

If you have a standard network name (eg. TP-Link_1234), a neighbor could accidentally connect to your router, confusing it with his own. Always change SSID (network name) to a unique one.

6. Additional measures to protect your Wi-Fi network

To minimize the risk of unauthorized connection, follow these guidelines:

1. Router settings

• 🔒 Turn it off WPS in the section Wireless → WPS.
• 🔄 Update your router firmware every 3–6 months.
• 📵 Disable remote control (Remote Management).
• 🕶️ Hide your SSID (network name) if it doesn't interfere with your devices.

2. Guest network

If you often have guests, create a separate guest network with limited access:

1. Find it in your router settings Guest Network.
2. Enable it and set a separate password.
3. Limit speed and access to local devices (such as printers).

3. Traffic monitoring

Use apps like GlassWire (For Windows/macOS) or Data Usage (For Android) to monitor unusual network activity. For example:

• 📥 A sharp jump in outgoing traffic.
• 🕒 Activity at night, when everyone is sleeping.
• 🌍 Connections to unfamiliar IP addresses (especially in other countries).

4. Two-factor authentication for the router

Some modern routers (for example, ASUS RT-AX88U or Keenetic) support login via SMS or app. This will protect your settings from being changed even if someone learns your password.

How to Check if Your Router Has Been Hacked

Go to settings and look at the section System Log or JournalIf there are suspicious entries about logging into the admin panel while you're away, the router is compromised. In this case, reset it to factory settings and install new firmware.

7. What to do if nothing helps

If you've blocked all unknown devices, changed your password, and updated your firmware, but other people's gadgets continue to appear online, it's possible:

1. The router is infected with malware

Some viruses (eg VPNFilter or Mirai) can open backdoors for remote control. Signs:

• 🔄 The router reboots spontaneously.
• 📡 Unknown open ports appear (checked via nmap or Fing).
• 🛠️ Unable to update firmware.

Solution: Reset your router to factory settings (Reset button for 10 seconds), then install the latest firmware from the official website.

2. Password leak due to cache hacking

If you've ever entered a Wi-Fi password on a public computer (like at an internet cafe), it may have been saved in your browser cache. Use password managers (KeePass, 1Password) and never save passwords in clear text.

3. Problems on the provider's side

In rare cases, your provider may allow other subscribers to access your network (for example, through a shared hotspot). Check with support to see if you have a feature like "Public Wi-Fi" or "Neighbor Network" enabled.

FAQ: Frequently asked questions about connected devices

Is it possible to find out who specifically connected to my Wi-Fi (name, address)?

No, you can only determine the MAC address or IP address device manufacturer (For example, Samsung or Apple). To identify a specific person, you will need the help of your provider or law enforcement agencies (they can track someone by IP, but only with a subpoena).

What should I do if my neighbor's router appears in the list of devices?

Most likely, you have the mode turned on Wi-Fi Repeater (repeater) or your router is connected to your neighbor's network as a client. Check the settings in the section Wireless → Bridge or Repeater and disable unnecessary features.

Can my neighbor connect to my Wi-Fi if I hide the SSID?

Yes, hiding the network name (Hide SSID) does not protect against connections. An experienced user can find your network by scanning the airwaves. This prevents accidental connections, but does not prevent targeted hacking.

How do I block a device if my router doesn't have a MAC filter?

In this case, all that remains is change password from Wi-Fi or disable DHCP and manually enter IP addresses for your devices. You can also try updating your router's firmware—sometimes new versions add missing features.

Is it true that WPA3 is more secure than WPA2?

Yes, WPA3 fixes some vulnerabilities WPA2 (for example, attack KRACK). However, not all devices support WPA3, so sometimes you have to use WPA2/WPA3 Mixed Mode. If all your devices are modern (released after 2019), feel free to switch to WPA3.

Now you know how check connected devices, identify other people's devices, and protect your network. Regular monitoring (at least once a month) will help avoid unexpected problems with traffic and internet speed. If you notice suspicious activity, don't delay blocking it and changing your password!
