A slow internet speed or intermittent connection interruptions are often the first signs that an unauthorized user has connected to your home network. Equipment owners TP-Link Users can easily check the current connection status through the built-in web interface, which provides detailed information about each active client. Modern cybersecurity requires constant monitoring, as even a well-known password can be compromised or shared with third parties without your knowledge.
The verification process does not require in-depth knowledge of network technologies and takes only a few minutes. You will be able to see IP addresses, MAC addresses and the names of all devices currently consuming your data. This allows you to quickly identify "uninvited guests" and block their access, restoring stable internet service at home.
Let's take a step-by-step look at how to access your router settings, where to find the client list, and what to do if you detect suspicious activity in your equipment logs.
Login to the router's web management interface
The first step to conducting a network audit is logging into the device's administrative panel. To do this, connect a computer or smartphone to the router. TP-Link by any available means: through Wi-Fi connection or with the help of LAN cable, which is usually included in the package. A wired connection is preferable, as it ensures a stable connection even if the wireless channel is congested.
Open any modern browser (Chrome, Firefox, Safari) and enter the default gateway IP address in the address bar. Most often, this is 192.168.0.1 or 192.168.1.1. The exact address, as well as the domain name (for example, tplinkwifi.net) are always indicated on a sticker located on the bottom of the router. The factory login and password are also located there.
⚠️ Important: If the default address doesn't open, check your computer's network card settings. The address must be obtained automatically (DHCP), otherwise you won't be able to see the router on the network.
After entering your login credentials, the main control panel page will open. The interface may differ depending on the firmware version: older models feature a classic menu on the left, while newer models feature a graphical interface with icons. We're interested in the section responsible for network status or wireless mode.
Finding a list of connected clients (Wireless Statistics)
In the router interface TP-Link Information about connected devices can be found in different sections depending on the model. In the classic green interface, go to the menu Wireless (Wireless mode) and select the item Wireless Statistics (Statistics) - This displays a table with the MAC addresses of all active wireless clients.
In more modern firmware versions, often referred to as the "blue" interface or Tether OS, the path may look different. You should look for the tab Basic (Basic settings) -> Wireless (Wireless mode) or a separate icon Map (Network Map), which visually displays all connected devices. Here you can see not only the MAC address but also the device name (Hostname), if it's being transmitted correctly.
The number of connected devices is usually displayed at the top of the page or in the status bar. If the number of clients exceeds the number of your personal devices, this is a reason to analyze each MAC address in detail.
Identifying devices by MAC address
The most difficult part of checking is understanding the exact device behind the string of numbers and letters in the MAC address column. Each network adapter has a unique identifier consisting of 12 hexadecimal characters separated by colons or hyphens. The first six characters (OUI) indicate the hardware manufacturer, such as Samsung, Apple, or Intel.
For ease of comparison, it's recommended to make a list of all your gadgets in advance. Go to the Wi-Fi settings on your smartphone, tablet, laptop, or smart TV. Samsung or LG, game consoles, and write down their MAC addresses. By comparing this list with the data in your router, you can easily identify the intruder.
If your list includes devices with names like "Unknown" or strange letter designations that aren't on your list, check their manufacturer using the first three pairs of characters using online OUI lookup services. This will help you determine the device type: camera, phone, or computer.
| Manufacturer (Example) | MAC Prefix (OUI) | Probable device | Status |
|---|---|---|---|
| Apple, Inc. | 00:1B:63 | iPhone / iPad / Mac | Mine |
| Samsung Electronics | 00:1A:2B | TV / Smartphone | Mine |
| Intel Corporate | 00:24:D6 | Laptop Wi-Fi adapter | Mine |
| Unknown vendor | XX:XX:XX | Suspicious gadget | Check! |
What is MAC address promiscuous mode?
Modern smartphones (iOS 14+, Android 10+) can use a randomized MAC address to enhance privacy. This can cause the device to appear new to the router, even if it's your phone. Disable this feature in your phone's Wi-Fi settings for the specific network so the router sees the real address.
Using the TP-Link Tether mobile app
For users who find it inconvenient to work with the browser version, the company TP-Link developed a free application Tether for iOS and Android. This is one of the fastest ways to check who is connected to your WiFi router. After installing the app and linking the router to your TP-Link ID account, you can access network management from anywhere with internet access.
The app's main menu includes a "Clients" section, which displays all connected devices in real time. The app automatically sorts them by type (mobile, computer, other) and allows you to give them user-friendly names. If you see a device you don't recognize, you can block it with the tap of a button.
The advantage of the mobile method is instantaneous Push notificationsYou can set up an alert for every new connection, allowing you to respond to network intrusions immediately, even when you're away from home.
☑️ Security check via Tether
Block unwanted devices and protect your network
If you discover a foreign device during the scan, you must immediately restrict its access. This can be done in the web interface using the Wireless MAC Filtering (MAC address filtering). You need to copy the MAC address of the intruder and add it to the Deny/Blacklist.
However, MAC address filtering is not a panacea, as an experienced user can clone the address of an authorized device. The most reliable method is to change the password for the wireless network. Go to Wireless -> Wireless Security and set a new, complex password. Encryption is recommended. WPA2-PSK or WPA3, since older WEP standards are easily cracked.
After changing your password, all devices will be automatically disabled. You'll have to re-enter the new access key on all your devices, but the "outsider" will lose connection forever if they don't know the new password.
⚠️ Caution: Changing your Wi-Fi password or filtering settings may cause your computer to lose connection to the router if you configured it wirelessly. Be sure to save your settings carefully.
Additional security measures and guest network
To minimize risks in the future, it is recommended to activate the function Guest network (Guest Network). This creates a separate SSID (network name) with its own password, which you can share with friends or acquaintances. The main advantage is that guests only have internet access and cannot see your personal files, printers, or other devices on the local network.
Also worth paying attention to is the function WPS (Wi-Fi Protected Setup). Despite the convenience of push-button connection, WPS technology has vulnerabilities that allow attackers to brute-force the PIN code. In the router settings TP-Link (chapter Wireless) It is better to disable this function (Disable).
Regularly updating your router firmware closes security holes that could allow hackers to access your client list or admin panel. You can check for updates in the section System Tools -> Firmware Upgrade.
Can my neighbor see my internet without a password?
Connection without a password is impossible if you have encryption enabled (WPA2). However, if the router is new and you haven't configured it, it may be operating in open mode or with a factory password, which is often written on the router and known to many.
Why is the device called "Unknown" in the client list?
This occurs if the device doesn't broadcast its hostname or the router can't recognize the manufacturer by its MAC address. This is often the case with IoT devices (smart light bulbs, sockets) or gadgets with MAC randomization enabled.
How often should I change my WiFi password?
It's recommended to change your password every 3-6 months, or immediately if you suspect someone may have discovered it. Passwords should also be changed when employees leave or when someone who knew the password leaves.
Does the number of connected devices affect the speed?
Yes, the Wi-Fi channel is shared among all active users. If someone is downloading large files or watching 4K videos, the speed on other devices may drop significantly, even if it's your own device.
