A slow internet connection is often the first warning sign that someone has accessed your wireless network. In the age of smart homes, where not only smartphones and laptops but also refrigerators, lamps, and robotic vacuum cleaners are connected to the internet, it's becoming increasingly difficult to keep track of every gadget. However, control of connected clients is a basic security feature that every router owner should be able to perform.
Company TP-LinkAs a leader in the networking equipment market, NETWORK provides users with intuitive tools for monitoring network activity. Whether you're using an older model of the series Archer or a modern system DecoThe principle of detecting "uninvited guests" remains similar, although the interfaces may differ. In this article, we'll examine in detail all the methods for checking a client list.
Early detection of a stolen device not only restores your internet speed but also protects your personal data from potential interception. Users often don't even realize that neighbors or passersby are using their traffic to download large files or torrents. Let's look at how to conduct a full audit of your home network.
Logging into the TP-Link router control panel
The first and most reliable way to obtain complete information about connected devices is to log into the device's web interface. To do this, your computer or smartphone must be connected to the router, either via Wi-Fi or a LAN cable. Open any browser and enter the gateway IP address in the address bar, which is the default for most models. TP-Link looks like 192.168.0.1 or 192.168.1.1.
If the default addresses don't work, check the sticker on the bottom of your router - it often contains a specific URL (e.g. tplinkwifi.net) or IP address to log in. After navigating to the address, the system will request authorization. The factory login and password are also indicated on the device label, usually admin And admin, if you haven't changed them before.
It is important to note that in new models with green or blue interface firmware, the login process may be combined with the creation of a cloud account. TP-Link IDThis provides additional protection but requires internet access. The older orange-and-white interfaces work locally and don't require mandatory registration for basic settings.
⚠️ Attention: If you changed the password for entering the router settings and forgot it, the only solution is to completely reset the device to factory settings using the button
ResetThis will delete all your current configurations, including provider settings.
Searching the client list in the new interface (blue/green)
Modern routers TP-Link are equipped with an updated interface, featuring a sleek design and easy navigation. After successful authorization, you'll be taken to the main status page, which often already displays a network map. For a detailed view, go to a section called Wireless (Wireless mode) or have a separate tab Clients (Clients) on the sidebar.
In the section Wireless Statistics (Wireless Statistics) displays a table with all active connections. Here you'll see the MAC address of each device, the current data transfer status, and the active time. This is the most accurate source of information, as it displays real-time data directly from the Wi-Fi module.
In some firmware versions, the client list is placed in a separate menu Basic → Wireless → Wireless StatisticsBy pressing the button Refresh (Refresh) will give you the current list for the current second. If a device hasn't transmitted data for a long time, it may disappear from the statistics list but remain listed as a DHCP client.
Checking connected devices in the old interface
Owners of earlier models such as TL-WR740N, TL-WR841N or the first versions Archer, you'll encounter the classic orange interface. The search logic here is slightly different, but no less effective. Find the tab in the left-hand menu. Wireless and select a subsection Wireless Statistics.
The window that opens will show a table where in the column MAC Address All addresses of connected devices are listed. A peculiarity of older firmware is that device names (Host Name) may not be displayed here, only MAC addresses and encryption status. To identify the owner, you will have to check these addresses against the stickers on phones and laptops.
Also, in the old interface, it is useful to look at the section DHCP → DHCP Client ListThis displays devices that have received an IP address from the router. The difference from Wi-Fi statistics is that it may also show devices connected via cable, as well as those that are currently idle but have not reset their IP address lease.
Don't be alarmed by the large number of rows in the table. Modern smartphones can create multiple virtual connections or have different MAC addresses for a private network, which increases the number of entries. However, if you see a clear excess of devices, it's worth conducting a more in-depth investigation.
What is MAC filtering?
MAC filtering is a network security method where the router allows only devices with pre-authorized physical addresses. Enabling this feature on older routers completely blocks access from strangers, even if they know the Wi-Fi password.
Using the TP-Link Tether mobile app
For users who prefer to manage their network from their smartphone, the company TP-Link developed an application TetherThis is one of the most convenient ways to quickly check who is using your Wi-Fi without turning on your computer. The app is available for iOS And Android and supports most modern router models.
After installing and linking the router to your account, you'll see a diagram of your network on the app's main screen. Click the icon Clients (Clients) or Devices, you'll get a complete list of connected devices with clear names and icons indicating the device type (iPhone, Windows, TV). This significantly simplifies identification compared to the tedious MAC addresses in the web interface.
A unique feature of the app is the ability to block access to an unwanted user with one click. A toggle switch or block button is often located next to the device's name in the list. This allows you to instantly disable a freeloading neighbor without having to delve into complex security settings.
| Function | Web interface | Tether app | TP-Link Deco app |
|---|---|---|---|
| View MAC addresses | Yes, in detail | Yes, in the properties | Yes |
| Blocking a client | Through filtration | In one click | In one click |
| Device names | Often no | Automatically | Automatically |
| Browsing history | No | No | Yes (in paid versions) |
Analyzing the list via DHCP clients
The section deserves special attention DHCP Server → DHCP Client ListProtocol DHCP Automatically assigns IP addresses to all devices on the network. The DHCP client list shows which devices the router has assigned an address to currently or during the lease period.
The advantage of this method is that it often displays Host Name (Hostname) of the device. You might see names like "Ivan-iPhone," "LivingRoom-TV," or "Samsung-Galaxy," making it easier to find your device. However, if you see the name "Unknown" or a suspicious name like "HUAWEI-P30" when you don't have such a phone, this is cause for concern.
Pay attention to the column Leased Time (Lease Time). This shows how long the assigned IP address is still valid. Even if the device is currently turned off or out of Wi-Fi range, it may still be listed until its lease expires. Therefore, to get a clear picture, it's best to first press the button. Clear All (Clear all) or wait for the lease to update and then check the list again.
Identifying devices by MAC address
The most complex, but also the most accurate verification method is MAC address analysis. A MAC address is a unique hexadecimal sequence (e.g., A4:5E:60:C2:1F:9B). The first three bytes (up to the second colon) are called OUI and indicate the manufacturer of the network interface.
Using online services or OUI tables, you can determine the device manufacturer. For example, if the address begins with 00:1A:2B, this may indicate Apple, A B8:27:EB - on Raspberry PiBy comparing the number of devices you know with the number of entries in the router, you can identify any unnecessary ones.
Modern smartphones based on iOS And Android Use the "Private Wi-Fi Address" feature. This means the phone generates a random MAC address for each new network. Such devices may appear as unknown in the router's list or change their addresses when reconnecting, making continuous monitoring difficult.
What to do if you spot a stranger
Discovering an unknown device in the list of connected clients requires an immediate response. The simplest, but not the most effective, method is to block it using the Blacklist (Blacklist) or MAC filtering settings. However, an experienced user can simply change their MAC address on their computer and bypass this protection.
The most radical and reliable solution is to completely change your wireless network password. Go to the section Wireless → Wireless Security and set a new complex password. It is recommended to use the encryption type WPA2-PSK or WPA3, because it is outdated WEP hacked in a few minutes.
After changing your password, all devices will be disabled. You'll have to re-enter the new password on all your devices. This will definitely lock out all unauthorized users from the network. It's also a good idea to disable this feature. WPS, which is often a loophole for unauthorized access.
⚠️ Note: TP-Link router interfaces are constantly being updated. The layout of menu items may vary depending on the firmware version. If you don't find the option described, search for a similar one or refer to the user manual on the official website.

Frequently Asked Questions (FAQ)
Why are there more devices in the client list than I have?
This is normal. Modern devices (TVs, set-top boxes, smartphones) can create multiple network interfaces or use different MAC addresses for different frequencies (2.4 GHz and 5 GHz). Furthermore, the list may still contain "dead souls"—devices that haven't renewed their IP address leases.
Can a TP-Link router automatically show the name of a connected phone?
Yes, newer models and firmware versions can recognize devices and display their names (e.g., "iPhone," "Xiaomi"). However, if this feature is enabled in the smartphone's privacy settings, the router will only see a random set of characters or the default manufacturer name.
How to permanently block access to a specific device?
The most reliable method is to use MAC address filtering in "Allow" mode. This will allow access only to devices whose addresses you manually whitelist. All others, even with the password, will be blocked.
Does the number of connected devices affect internet speed?
Absolutely. The Wi-Fi channel is shared between all active clients. If one of the connected devices starts downloading a large file or watching a 4K video, the speed on the other devices will drop significantly, even if it's your own TV.
