Who's Connected to My TP-Link Wi-Fi? All the Ways to Check

Have you noticed your internet has slowed down and your data usage is unusually high? Perhaps unauthorized devices have connected to your Wi-Fi. Routers TP-Link offer several ways to track active network users—from the standard web interface to mobile apps and specialized utilities. In this article, we'll explore all available methods, including hidden features of some models, and explain how to not only see connected, but also block unwanted guests.

It is important to understand that there are different models TP-Link (For example, Archer C6, TL-WR841N or Deco M5) may have differences in the interface, but the general testing principle remains the same. If you're using a dual-band router, be sure to check both frequency bands— 2.4 GHz And 5 GHz — separately. Also note that some devices (such as smart light bulbs or IP cameras) may appear under non-obvious names.

Before testing, make sure you're connected to the same network as your router—either via cable or Wi-Fi. If you're trying to test the network remotely (for example, via mobile data), access to the settings will be blocked for security reasons.

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

The web interface is your router's control panel, accessible through a browser. Here you can see not only a list of connected devices, but also their MAC addresses, IP, and connection time. To get there:

1. Open any browser (Chrome, Firefox, Edge) and enter in the address bar 192.168.0.1 or 192.168.1.1If none of the addresses work, check the sticker on the back of the router - it contains the correct IP address.
2. Enter your login and password (usually by default admin/admin, if you haven't changed it). If you forgot the data, reset the router using the button Reset (hold for 10 seconds).
3. Go to the section DHCP → DHCP Clients or Wireless Mode → Wireless Mode Statistics (the name may differ depending on the model).

In the table, you'll see all devices connected to the network. Note the following columns:

• 🔹 Host name — the name of the device (if configured). Often displayed as the model of a smartphone or laptop (e.g., iPhone-12-Pro or Xiaomi-11T).
• 🔹 MAC address — a unique device identifier. This can be used to block access.
• 🔹 IP address — a local address on your network (for example, 192.168.0.103).
• 🔹 Rental time - shows how long the device has been using your Wi-Fi.

If there are any unknown devices in the list, write them down. MAC addresses — they will be needed for blocking. Some routers TP-Link allow you to immediately lock the device directly from this menu (button Block or Block).

Change your Wi-Fi password to a more complex one (at least 12 characters) -->

⚠️ Attention: Some devices (such as smart speakers or cameras) may connect to the network automatically and appear under technical names like ESP_123456 or Home-AssistantBefore blocking, make sure it is not your gadget.

2. Using the Tether mobile app

Application TP-Link Tether (available for Android And iOS) simplifies router management from your smartphone. It displays a list of connected devices in real time and allows you to quickly block unwanted users. To use it:

1. Download TP-Link Tether from App Store or Google Play.
2. Launch the application and log in using the login/password from the router (the same as for the web interface).
3. Select your router from the list (if there are several).
4. Go to the section Devices or Clients (depending on the application version).

IN Tether Devices are displayed with icons (smartphone, laptop, TV, etc.), making them easier to identify. To block a device:

1. Click on the unknown gadget in the list.
2. Select an option Block or Block.
3. Confirm the action.

The application also allows you to install traffic limits For individual devices or time restrictions (for example, turning off a child's internet after 10:00 PM). This feature is not available on all router models.

⚠️ Attention: If you are using a mesh system TP-Link DecoTo manage devices, you need to download a separate application Deco, and not TetherIt offers broader functionality, including the ability to create a "guest network" with limited access.

3. Viewing via the command line (for advanced users)

If you have access to a computer running Windows, macOS or LinuxYou can use the command line to scan your network. This method won't show devices connected to the router via cable, but it will help identify all those using Wi-Fi.

For Windows:

arp -a

This command will list all devices on the local network with their IP and MAC addresses. To filter only active connections, use:

arp -a | findstr "192.168"

For macOS/Linux:

nmap -sn 192.168.0.0/24

If nmap is not installed, it can be downloaded from the official website. The command will scan all IP addresses in the range 192.168.0.1–192.168.0.255 and will show active devices.

To identify a device manufacturer by MAC address, use the first 6 characters (e.g. B8:27:EB - This Raspberry Pi, 78:31:C1 — Apple). For this, you can use online services like MAC Vendor Lookup.

4. Third-party network monitoring programs

If standard methods don't work, you can use specialized utilities. They not only display connected devices but also analyze their activity, data usage, and even geolocation (if it's a smartphone). Popular apps:

• 🖥️ Wireless Network Watcher (free, for Windows) - scans the network and displays all devices with manufacturer, IP, and MAC address. You can export the list to .csv.
• 📱 Fing (For Android/iOS) — identifies devices on the network, checks for open ports and vulnerabilities. It also provides notifications about new connections.
• 🌐 GlassWire (For Windows/macOS) — monitors traffic in real time and shows which devices consume the most data.
• 🔍 Angry IP Scanner (cross-platform) - quickly scans the local network and displays a list of hosts with additional information.

The advantage of third-party programs is that they often show hidden devices, which aren't displayed in the router's web interface (for example, if an attacker has spoofed the MAC address). However, be careful: some utilities require administrator rights and may conflict with antivirus software.

Sample report from Wireless Network Watcher:

Device Name     | IP Address      | MAC Address       | Network Adapter Company
----------------|-----------------|-------------------|--------------------------
DESKTOP-123     | 192.168.0.101   | 00-1A-79-XX-XX-XX | Dell Inc.
iPhone          | 192.168.0.103   | A4-83-E7-XX-XX-XX | Apple
Unknown | 192.168.0.105 | 78-31-C1-XX-XX-XX | Apple (possibly Apple TV)

⚠️ Attention: Some programs (eg Fing) may recognize devices as "unknown," even if they belong to you. This happens because the manufacturer's information is missing from the database. In this case, check the MAC address manually.

5. How to block other people's devices on the TP-Link network

If you find a suspicious device, there are several ways to block it. The most reliable is MAC address filteringTo do this:

1. Go to the router's web interface (192.168.0.1 or 192.168.1.1).
2. Go to the section Wireless Mode → MAC Filtering (or Wireless → Wireless MAC Filtering).
3. Activate filtering by selecting the option Turn on.
4. Add the MAC address of the unwanted device to the blacklist and save the settings.

Alternative methods:

• 🔄 Changing your Wi-Fi password — the easiest way to kick out all strangers. Use a complex password (for example, K7#pL9!mQ2@xY4) with letters, numbers and symbols.
• 🌐 Hiding the SSID - disable network name broadcasting in the settings (Wireless → Wireless Settings → Hide SSID). This won't protect you from experienced hackers, but it will stop random connections.
• 🛡️ Guest network - create a separate network for guests with limited access to local resources (settings in the section Guest network).

If an attacker has spoofed the MAC address of one of your devices, MAC blocking won't help. In this case, the only reliable solution is to change your Wi-Fi password and enable WPA3 encryption (if supported by your router).

6. Why do unknown devices appear in the list?

An unknown device on the network isn't always a hacker. Often, it's:

• 📱 Smart gadgets - light bulbs Yeelight, sockets TP-Link Tapo, robotic vacuum cleaners Xiaomi are often connected automatically and displayed under technical names.
• 🖥️ Old devices - a forgotten laptop that hasn't been used for a long time, but remains online.
• 🎮 Game consoles — PlayStation, Nintendo Switch or Xbox can be displayed as Unknown Device.
• 📡 Neighboring routers - If you have a weak password, neighbors may connect automatically (especially if the network has a standard name like TP-Link_1234).

To identify your device:

1. Disconnect all your gadgets (smartphones, laptops, TV) from the network.
2. See what devices are left in the list.
3. Turn on your devices one by one and see which name appears on the list.

If the unknown device remains, try pinging its IP address:

ping 192.168.0.105

If the answers come (for example, Reply from 192.168.0.105), the device is active. If not, it might be a "dead" IP address that the router hasn't released yet.

What to do if an unknown device cannot be pinged?

This may mean that:

1. The device has disconnected from the network, but the router has not yet updated the list (wait 5-10 minutes and check again).

2. This is a "sleeping" gadget (for example, a smartphone in power saving mode) that does not respond to requests.

3. The attacker uses tools to hide activity (for example, by disabling ping responses).

In the latter case, it is recommended to change the Wi-Fi password and enable WPA3 encryption.

7. How to prevent unauthorized connections in the future

To minimize the risk of re-invasion, follow these guidelines:

1. Use WPA3 - if your router supports this standard (available on models Archer AX, Deco X etc.), enable it in the security settings (Wireless → Security Settings → WPA3-Personal).
2. Disable WPS This feature simplifies connection, but is vulnerable to hacking. It can be disabled in the section Wireless Mode → WPS Settings.
3. Update your firmware — Manufacturers regularly patch vulnerabilities. Check the latest version in the section System Tools → Firmware Update.
4. Turn on notifications — in the appendix Tether or through third-party utilities (for example, Fing) set up notifications about new connections.

Also useful:

• 🔧 Change your password regularly — at least once every 3–6 months.
• 📡 Disable guest network, if it is not used.
• 🛡️ Use a VPN on a router (if supported) for additional traffic protection.

If you suspect that your router has been hacked (for example, the settings have been changed without your intervention), perform a full reset to factory settings (button Reset for 10 seconds) and set it up again.

FAQ: Frequently asked questions about connected devices in TP-Link

Is it possible to see what websites connected devices are visiting?

No, routers TP-Link do not provide this feature in the standard firmware. Third-party software (e.g., OpenWRT with installed ntopng) or setting up a proxy server. Please note that intercepting traffic may violate privacy laws.

Why is my router showing up in the list of connected devices?

This is normal - the router may appear as a device with an IP 192.168.0.1 or 192.168.1.1. Also, duplicate entries may appear in the list if you have enabled DHCP server and devices receive dynamic IP addresses. To clear the list, reboot the router.

How do I find out how much traffic each device is consuming?

In the web interface TP-Link go to the section Advanced → Traffic Statistics (or Advanced → Traffic Statistics). Here you can see the volume of downloaded and sent data for each device. In the mobile app Tether This feature is available in the section Devices → Details.

What should I do if I can't access my router settings (192.168.0.1 won't open)?

Possible causes and solutions:

• 🔌 Check the physical connection - if you are using a cable, make sure it is plugged into the port LAN (Not WAN).
• 🌐 Make sure your computer gets an IP address automatically (the network adapter settings should be in automatic mode) DHCP).
• 🔄 Try a different browser or clear your cache.
• 📡 Check your router's IP address via the command line (ipconfig For Windows or ifconfig For macOS/Linux) - look for the line Main gateway.

If nothing helps, reset the router using the button Reset.

Is it possible to block a device permanently?

MAC address blocking remains in effect until you reset the router or manually delete the rule. However, an experienced user can spoof their device's MAC address and bypass the blocking. For reliable protection, it is recommended to combine several methods: complex password + WPA3 + disabling WPS.
