Many users notice a sharp drop in internet speed or unstable wireless network performance without understanding the cause. Often, the culprit is unauthorized devices accessing your network without the router owner's knowledge. Equipment owners TP-Link can easily check the list of connected gadgets through the web interface or mobile app to ensure the security of their channel.
In this article, we'll detail the steps for different firmware versions, as the menu interface can vary significantly. You'll learn how to distinguish your devices from others, understand which parameters to check, and discover how to instantly disable an uninvited guest. Traffic control β this is the first step to ensuring digital security on your local network.
Before proceeding with the settings, make sure you have physical or wireless access to the router. Checking the client list is only possible if you have a connection to the device distributing Wi-Fi. If you're away from home and haven't set up remote management, remote diagnostics won't be possible.
Symptoms and signs of unauthorized access
The first sign that your Wi-Fi is being used by neighbors or passersby is usually a noticeable drop in page loading speeds and video streaming. Even with a high-bandwidth plan, the channel can become clogged if someone is downloading large files or using torrent trackers in the background. Indicators The lights on the router body may flash randomly, even when you are not using the Internet.
Another warning sign is the inability to connect to your own network due to an error message stating that an IP address could not be obtained. This occurs when the DHCP address pool is exhausted, meaning all available network slots are already occupied by other devices. In such situations, the router simply cannot assign a new address to your smartphone or laptop.
Pay attention to the behavior of connected devices: they may lose connection or take a long time to find a network. This is a classic sign. IP address conflict or overloading the radio module with extraneous traffic. If you live in an apartment building, the likelihood of signal interception is high, especially if you have a weak password or use the outdated WEP encryption method.
Preparing for testing: accessing the router settings
To begin diagnostics, you need to log in to the device's control panel. Open any browser on a computer or phone connected to the TP-Link network and enter the default gateway address in the address bar. Most often, this is 192.168.0.1 or 192.168.1.1, but the address can be changed by the user earlier. The exact IP address, username, and default password are indicated on a sticker located on the bottom of the router.
After entering the data, you will be taken to the quick setup page or the main menu, the appearance of which depends on the firmware version. Older models use an orange and green interface, while newer devices that support the standard Wi-Fi 6 and cloud features have a blue and white menu design. Please enter your password carefully, as the system is case-sensitive.
βοΈ Preparing to log into the router
If the default login details don't work, they may have been changed during a previous setup. In this case, you'll need to perform a factory reset by holding down the button. Reset on the case. Please note that after this procedure, your internet will stop working until you reconfigure your ISP's connection settings.
Checking clients in the classic interface (green/orange)
For owners of previous generation routers, such as the series Archer C20, TL-WR840N or TL-WR740N, you're probably familiar with the old interface. To find out who's connected to Wi-Fi, find the section in the left-hand menu. Wireless (Wireless mode) and select the subsection Wireless Statistics (Wireless Statistics) - This displays a table with all active connections.
In the window that opens, you'll see a list of MAC addressesβunique identifiers for network cards. The number of rows in the table corresponds to the number of connected devices. If you see more devices than you have in your hands, there are extra users on the network. For more detailed information, see the section DHCP -> DHCP Client List, where not only addresses but also device names are indicated.
β οΈ Note: On some older firmware versions, the list may not update in real time. Be sure to press the button Refresh (Refresh) to see the latest connection picture right now.
You can identify your device in the list by the MAC address specified in your phone or laptop settings. Other unknown addresses most likely belong to intruders. Write down suspicious MAC addresses so you can add them to the filtering blacklist later.
Connection Analysis in the New Interface (Blue/Cloud)
Modern models, for example Archer AX20, AX50 or AX73, use an updated operating system with a more visual network display. After logging in, the main page ("Network Map") often immediately displays the number of connected clients. For a detailed view, click on the device icon or go to the section Basic (Basic settings) -> Wireless (Wireless mode).
Here, the client list is presented in a more convenient format: the device name (for example, "iPhone-Ivan" or "Samsung-TV") is often displayed next to the MAC address. This significantly simplifies identification, as there's no need to check the numbers against the stickers on the devices. New firmware also allows you to sort devices by frequency: 2.4 GHz or 5 GHz.
Why might the device name be displayed incorrectly?
The name the router sees is transmitted by the client device itself. If a user-friendly name isn't specified in the smartphone or PC settings, the router may display a generic name like "Unknown" or "Android-1234." This isn't a router error, but a client configuration issue.
A key feature of the new interface is the ability to manage devices directly from the list. By clicking on a specific device, you can see its IP address, connection speed, and activity time. Visualization helps you instantly understand which device is consuming the resource right now.
Using the TP-Link Tether mobile app
The fastest way to check who is connected to your TP-Link router's Wi-Fi is to use the official app. Tether for Android or iOS. This method doesn't require entering IP addresses and works even if you're connected to the network via mobile data (provided remote management is enabled). The app automatically detects the router on the network and prompts you to log in with your administrator password.
The app's main menu features a "Clients" section or an icon with a picture of connected devices. Tapping it will display a full list of all devices connected to the network. The app often displays not only the name and MAC address but also the network card manufacturer (e.g., Apple, Intel, Xiaomi), which helps identify the device.
| Parameter | Web interface (PC) | Tether App (Mobile) |
|---|---|---|
| Availability | Only within Wi-Fi network | On-network and remote (4G/5G) |
| Convenience | Average (need to look in the menu) | High (all on main screen) |
| Blocking | Through MAC address filtering | One button in the list |
| Detailing | High (full logs) | Basic (name, type, status) |
The convenience of the mobile app lies in its instant response. If you see a stranger, you can block them with one tap, without having to navigate through complex settings menus. This is especially useful when you need to act quickly.
How to Block Someone Else's Device and Protect Your Network
Once you detect an intruder, you must immediately restrict their access. The most reliable method is to use MAC address filtering (MAC Filtering). In the router menu (usually the section Wireless -> Wireless MAC Filtering) You need to add the intruder's MAC address to the blocked list and enable the "Deny" rule. After saving the settings, the device will lose connection to the router.
In new TP-Link interfaces, the process is even simpler: the client list often features a "Block" or "Isolate" toggle. Clicking it automatically blacklists the address. However, this isn't complete security, as a hacker can change their device's MAC address and attempt to connect again.
Be sure to change your wireless network password to a complex one that contains mixed-case letters and numbers. Make sure that in the security settings (Wireless Security) the encryption protocol is selected WPA2-PSK or WPA3The WEP and WPA/TKIP protocols are considered obsolete and can be easily cracked with specialized software in a few minutes.
β οΈ Important: MAC address filtering does not encrypt transmitted data. An attacker within range can see your traffic unless you use strong WPA2/AES encryption. Always change your password, not just block addresses.
After all changes, it is recommended to reboot the router through the menu System Tools -> RebootThis will apply all new security rules and clear the connection cache. Check the client list regularly, especially if you live in a densely populated area.
Frequently Asked Questions (FAQ)
Can a router show the name of another device?
The router displays the name the device broadcasts to the network (Hostname). If the smartphone owner has set the hostname to "MyPhone," you'll see it. If the default "Android" or the field is empty, the router will only show the MAC address and chip manufacturer.
What should I do if I don't remember the password for my router settings?
If the password for the web interface (not the Wi-Fi one, but the admin panel password) has been changed and lost, a hard reset is the only solution. Hold the reset button for 10 seconds, and the router will return to factory settings, and the password will be the same as on the sticker.
Does the number of connected devices affect the speed?
Yes, directly. The Wi-Fi channel is shared among all active users. If you have 10 other devices connected to your network downloading updates or videos, your speed can drop to practically zero.
Is it possible to find out what websites someone else's device is visiting?
TP-Link's standard firmware doesn't have this feature. Viewing browsing history (URL filtering) requires more complex logging settings or installing third-party firmware (such as OpenWrt), but even this won't allow you to see the contents of HTTPS traffic.
