How to See Who's Connected to Your Wi-Fi: A Complete Guide with Instructions

Have you noticed your internet has slowed down even though your plan hasn't changed? Or has your router started rebooting frequently for no apparent reason? Perhaps unauthorized devices have connected to your Wi-Fi network—neighbors, guests who forgot to disconnect, or even hackers exploiting security vulnerabilities. According to research KasperskyEvery fifth router in Russia has weak passwords or outdated encryption protocols, making them an easy target for unauthorized access.

In this article you will find 7 proven methods, how to find out who is connected to your Wi-Fi - from simple methods through a mobile app to advanced tools like arp-scan And nmapWe will also tell you how block other people's devices and protect your network from repeated intrusions. These instructions are suitable for routers. TP-Link, ASUS, Keenetic, Zyxel, MikroTik and other popular brands.

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

The most reliable way is to access your router's control panel. This doesn't require any additional software, just a browser and access to your local network. The steps are the same for most models, but the paths to the sections may vary slightly.

First, open your browser and enter your router's IP address in the address bar. This is usually:

• 🔹 192.168.0.1 - For TP-Link, D-Link, Tenda
• 🔹 192.168.1.1 - For ASUS, Zyxel, Netis
• 🔹 192.168.8.1 - for some models Huawei
• 🔹 my.keenetic.net — for routers Keenetic

If the standard addresses don't work, you can find out the exact IP address using the command line:

1. Click Win + R, enter cmd and press Enter.
2. Enter the command ipconfig and find the line Main gateway - this is the IP of your router.

After logging into the control panel (usually you need to enter your login and password, by default it is admin/admin (Or indicated on the router sticker), find the section with connected devices. It may be called:

• 📡 DHCP Clients List (at TP-Link)
• 📡 Clients or Devices (at Keenetic)
• 📡 Network Map (at ASUS)
• 📡 Connected Devices (at Netgear)

2. Using mobile apps (for quick checking)

If you need to quickly check connected devices without logging into the web interface, use the official apps from router manufacturers. They are free and available for Android And iOS.

Here are the most popular apps:

• 📱 Tether (For TP-Link) — displays a list of devices, traffic consumption speed, and even allows you to block suspicious gadgets.
• 📱 ASUS Router — displays a network map with IP addresses, MAC addresses and host names.
• 📱 Keenetic — has a built-in network scanner and parental control function.
• 📱 WiFi Master Key (from Linksys) - scans the network and shows all connected devices, even if they are hidden.

The advantage of mobile applications is a user-friendly interface and the ability to receive notifications about new connections. For example, in Tether You can set up alerts if an unknown device connects to the network.

However, this method has its disadvantages:

• ⚠️ Not all routers support official apps (especially older models).
• ⚠️ Some applications require registration and linking to the manufacturer's account.

3. Windows Command Prompt: Who's Connected to Wi-Fi Without Programs

If you don't have access to the router's control panel (for example, you're not a network administrator), you can use the built-in tools. WindowsThis method will show the devices that are active on your local network, but will not provide information about those connected to the router via Ethernet or other Wi-Fi networks (if the router has multiple SSIDs).

Open Command Prompt (Win + R → cmd) and execute the commands sequentially:

arp -a

This command will display the ARP (Address Resolution Protocol) table, which will list the IP and MAC addresses of devices your computer has recently interacted with. Look for lines with IP addresses from your subnet (e.g., 192.168.1.x).

For a more complete list, use:

nbtstat -a [IP address]

Replace [IP address] to a specific address from the list arp -aThis command will attempt to determine the name of a device on the network. Windows (if it discloses it).

For advanced users, this utility is suitable ping paired with arp:

1. Do it ping 192.168.1.255 (replace 192.168.1 to your subnet).
2. Immediately after this, enter again arp -a - now all active devices on the network will appear in the list.

What is a MAC address and why is it important?

A MAC (Media Access Control) address is a unique identifier assigned to a network interface at the factory. It appears as six pairs of hexadecimal numbers, such as 00:1A:2B:3C:4D:5EKnowing the MAC addresses of legitimate devices (smartphones, laptops, smart speakers), you can block all others in your router settings using MAC filtering. However, this method isn't foolproof, as MAC addresses can be spoofed.

4. Special programs for network scanning

If you need to not only see connected devices but also analyze their activity (for example, which devices are consuming the most traffic), use specialized programs. These are suitable for experienced users and small network administrators.

For most home users it will be enough Angry IP Scanner or FingThese programs do not require installation (there are portable versions) and show:

• 🔍 IP and MAC addresses of devices
• 🔍 Hostnames (if allowed by the device)
• 🔍 Network card manufacturer (by MAC address)
• 🔍 Device status (online/offline)

Example of using Angry IP Scanner:

1. Download the program from the official website angryip.org (the free version will do).
2. Run a scan of your network's IP range (e.g. 192.168.1.1-192.168.1.255).
3. In a few seconds you will see a list of all active devices.
4. Export the report to CSV for further analysis.

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

If you detect a foreign device on your network, you need to block it. This can be done in several ways, depending on your router model.

Method 1: Filtering by MAC address

1. Go to the router's web interface (instructions in first section).
2. Find the section MAC Filtering (or MAC address filter).
3. Add the MAC address of the suspicious device to the blacklist.
4. Save the settings and reboot the router.

Method 2: Change your Wi-Fi password

The easiest and most effective method is to change your network password. To do this:

1. In the router control panel, find the section Wireless Settings (or Wi-Fi settings).
2. In the field Password (Password) Enter a new complex password (we recommend using at least 12 characters with numbers, letters and special characters).
3. Select encryption type WPA2-PSK or WPA3-PSK (if supported).
4. Save the changes - all devices will be disconnected and will need to reconnect.

Method 3: Disabling DHCP for a specific IP

If the attacker uses a static IP, you can block them by binding:

1. In the section DHCP Reservation (DHCP Reservation) find the IP address of someone else's device.
2. Bind it to a non-existent MAC address (eg. 00:00:00:00:00:00).
3. Save the settings - the device will not be able to obtain an IP address from the router.

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

Even after blocking other people's devices, it's important to take steps to prevent further intrusions. Here 5 Key Recommendations From cybersecurity experts:

• 🔒 Use WPA3 - if your router supports WPA3-PSK, turn it on. This protocol is harder to hack than the outdated one. WPA2.
• 🔒 Disable WPS — function Wi-Fi Protected Setup has vulnerabilities that allow someone to guess a PIN code in a few hours. Disable it in your router settings.
• 🔒 Hide your SSID - Disable the option in the Wi-Fi settings Enable SSID BroadcastYour network won't be visible in the list of available networks, but you can still connect to it manually.
• 🔒 Update your firmware — Manufacturers regularly release patches for vulnerabilities. Check for updates in the section Firmware Upgrade.
• 🔒 Enable guest network If you have frequent guests, create a separate network with limited access to local resources.

Important: If your router is older than 5 years, consider replacing it. Older models (e.g., TP-Link TL-WR740N or D-Link DIR-300) often have unfixable vulnerabilities in the firmware.

For additional protection you can use:

• 🛡️ VPN on a router - some models (for example, ASUS RT-AX88U) support the installation of a VPN server, which encrypts all traffic.
• 🛡️ Firewall on the router — In the security settings, enable the built-in firewall and block suspicious ports.

7. Common Mistakes and Myths About Wi-Fi Security

Many users follow advice that not only doesn't help, but can actually worsen security. Let's address the most common misconceptions:

⚠️ Attention: Using a complex password like 12345678 or qwertyuiop does not protect against hacking. Modern brute force programs (Aircrack-ng, Hashcat) can be used to generate such combinations in just a few minutes. The password must be at least 12 characters long, including mixed case, numbers, and special characters.

Myth 1: "Hiding the SSID makes the network invisible to hackers."

In fact: A hidden SSID does not protect against scanning. Any network analyst using Wireshark or Kismet can detect your Wi-Fi even if it's not broadcasting. Hiding the SSID only makes it more difficult for legitimate users to connect.

Myth 2: "MAC address filtering is reliable protection"

In fact: MAC addresses are easy to spoof (this is called MAC-spoofing). A skilled attacker can "spoof" your device's MAC address and gain access to the network.

Myth 3: "If the internet is fast, it means no one is connected."

Fact: Modern hackers can use your Wi-Fi to hidden mining, DDoS attacks or traffic proxying, without overloading your channel. Check the network even if the speed is stable.

Myth 4: "Updating your router's firmware is not necessary."

In fact: Manufacturers regularly discover critical vulnerabilities. For example, in 2023, a vulnerability was discovered CVE-2023-1389 in routers TP-Link, allowing remote code execution. Updates close such vulnerabilities.

⚠️ Attention: If you are using a router from a provider (for example, Rostelecom or MTS), its firmware may be blocked from updating itself. In this case, request an update from technical support or replace the device with a neutral one.

FAQ: Answers to Frequently Asked Questions

Is it possible to find out who is connected to my Wi-Fi if I'm not the network admin?

Yes, but with limitations. You can scan your local network using Angry IP Scanner or Fing, but you'll only see devices on the same subnet as your computer. If your router separates networks (for example, primary and guest), you won't see devices from other subnets. You also won't be able to block someone else's device without access to the control panel.

How to determine what kind of device it is with an unknown MAC address?

By the first three bytes of the MAC address (for example, 00:1A:2B) you can determine the manufacturer of the network card. To do this:

1. Copy the MAC address.
2. Go to the website MAC Vendors Lookup.
3. Paste the address into the search bar - the service will show the manufacturer (for example, Apple, Samsung, Xiaomi).

This won't give you the exact model of your device, but it will help you figure out whether it's a smartphone, a laptop, or, for example, a smart light bulb.

Can my neighbor connect to my Wi-Fi if I use WPA3?

Theoretically possible, but extremely unlikely. WPA3 eliminates major vulnerabilities WPA2 (for example, attacks KRACK). However:

• If the password is weak (for example, 1234567890), it can be selected by brute force.
• If your router is outdated, its WPA3 implementation may have bugs (such as a vulnerability Dragonblood in earlier versions).
• If an attacker has physical access to the router, they can reset it to factory settings.

For maximum security, combine WPA3 with disabling WPS, regular password changes And monitoring of connected devices.

What should I do if my router has been hacked and its settings have been changed?

If you can't access the control panel (the password doesn't work or the router's IP address has changed), follow these steps:

1. Reset your router to factory settings - To do this, press and hold the button Reset (usually it is recessed into the body and requires a paper clip) within 10-15 seconds.
2. Connect to the router via cable - After the reset, Wi-Fi will be disabled, so use Ethernet.
3. Go to the control panel via standard IP (see first section) with default login/password (usually admin:admin).
4. Update your firmware immediately and change your Wi-Fi and control panel passwords.
5. Check your network for viruses - some malicious programs (for example, Mirai) can infect routers and use them for attacks.

If your router is unstable after a reset, its firmware may be corrupted. In this case, you'll need to reflash the device manually (instructions are available on the manufacturer's website).

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

No, from the router data you can only find out:

• Device MAC address;
• IP address in the local network;
• Host name (if disclosed);
• Network card model (by MAC).

Determine the physical location (e.g. a neighbor's apartment) from this data impossibleThis requires specialized law enforcement tools that track signals by triangulating access points (and even then, the accuracy is tens of meters).

If you suspect your Wi-Fi is being used for illegal activities (such as distributing pirated content), contact your ISP. They can help identify the perpetrator from their logs.
