How to find out how many connections are active on a TP-Link WiFi router: instructions

A sudden drop in internet speed or intermittent connection interruptions often indicate that unauthorized users have connected to your wireless network. Many router owners are unaware that neighbors or more tech-savvy friends may be using their connection for their own purposes. This not only reduces network performance but also creates potential security risks for your personal data.

Company TP-LinkAs a leader in the network equipment market, we offer several ways to monitor client activity. Whether you're using a modern model that supports the standard Wi-Fi 6 If you have an older router, information about connected devices is available in the control panel. In this article, we'll cover all the verification methods in detail and learn how to distinguish your gadgets from others.

Timely diagnostics not only help identify freeloaders but also detect forgotten old devices that continue to consume bandwidth in the background. Understanding how the client list works is the first step to building a reliable home network. We'll cover both the classic web interface and mobile apps for operational monitoring.

Using the web interface to check clients

The most reliable and informative way to get a complete list of connected devices is to access the router settings through a browser. This method provides access to advanced information, including MAC addresses and connection type, which is critical for accurate identification. You'll need any device (laptop, smartphone, or tablet) that's already connected to the router's network.

To begin, you need to open any browser and enter the router's IP address in the address bar. By default, for most models TP-Link This 192.168.0.1 or 192.168.1.1If the default address was changed earlier, you can find the current one through the Windows command line by entering the command ipconfig and find the line "Default gateway".

⚠️ Attention: If you haven't changed the administrator password and the default one (usually admin/admin) doesn't work, the settings may have been previously changed. In this case, you'll need to perform a full factory reset of the router using the reset button. Reset on the body.

After successful authorization, the interface may look different depending on the firmware version. On newer models with updated OS, the interface often has a green or blue color scheme, with the status displayed on the main screen. On older firmware versions (orange or blue and white interface), you need to navigate to specific menu tabs to find information.

Searching for a list of clients in the new interface (green/blue)

Owners of modern models such as the series Archer, they'll likely see a graphical interface with a network map. Visualization plays a key role here: the main screen often displays a diagram with the router itself as the central element, with lines extending from it to connected devices. A number next to the "Wireless" or "Clients" icon indicates the current number of active connections.

To get detailed information, click on the section Wireless (Wireless mode) or directly on the block with the image of connected devices. A window will open listing all the gadgets. It's important to pay attention not only to user-defined names (e.g., "iPhone-Ivan") but also to their technical identifiers.

The interface allows you to sort devices by connection type: wired (LAN) or wireless (WiFi). This is convenient if you want to check which devices are connected to the network and which are connected via cable. A blocking function is often available in this menu: next to each device, there may be a switch or button to deny access.

Instructions for the old interface (orange/blue)

If your router is an older model or hasn't been updated in a while, you'll be taken to the classic menu with a vertical or horizontal navigation list. The logic here is slightly different, and accessing the information you need requires several steps. Don't be intimidated by the abundance of menu items—we're only looking for one specific tab.

Find the section in the side menu Wireless (Wireless mode). A submenu will open inside it, where you need to select the item Wireless Statistics (Wireless Statistics) or Connected Devices (Connected devices). In some firmware versions, this information may be located in the DHCP -> DHCP Client List.

The table that opens will show MAC addresses, IP addresses, and lease time. Lease time is a useful parameter: if it expires in a few minutes, the device is likely active right now. If it's longer, the device may have connected a long time ago and is currently in sleep mode or out of range.

What should I do if the list is "empty" but the internet is slow?

If the counter shows zero connected devices but the speed is low, WiFi theft may not be the issue. Check your neighbors' bandwidth usage using WiFi analyzer apps or check for background updates on your own devices.

Checking via the TP-Link Tether mobile app

For users who prefer to manage their network from a smartphone, the company has developed a convenient application TP-Link TetherThis is the fastest way to check your network status without turning on your computer. The app is available for platforms Android And iOS and allows you to control most modern router models.

After installing and linking the router to an account (or logging in locally), the main screen displays a pie chart or a list of clients. The app automatically detects the device type by its icon (phone, laptop, camera) and its name. By clicking on a specific device, you can see the current connection speed and the amount of data transferred.

The app's convenience lies in its instant blocking feature. Simply click the switch next to the suspicious device, and network access will be blocked. It also features a "Guest Network" feature, which we'll cover below. Notifications about new connections can be enabled in the app settings to stay informed.

How to identify devices by MAC address

The most common problem when checking the connection list is strange names like "Unknown" or strings of numbers and letters. Device names are often not transmitted correctly or are arbitrarily entered by users. The only reliable method of identification is MAC address (physical address) which is unique for every network module in the world.

A MAC address consists of 12 characters (numbers and letters from A to F), separated by colons or hyphens (e.g. 00:1A:2B:3C:4D:5E). The first six characters (OUI) indicate the device's manufacturer. Knowing the manufacturer, you can guess what kind of gadget it is: Apple, Samsung, Intel, or Espressif (often smart plugs or light bulbs).

To check your devices, go to the WiFi settings on your phone or laptop, find the connection information, and look at the "Physical Address" or "MAC Address" line. Compare it with what you see in the router's list. Any mismatched addresses are potential candidates for blocking.

Below is a table with examples of MAC address prefixes from popular manufacturers to help you navigate the client list more quickly:

Network protection: blocking and filtering

Once you detect an intruder, you need to immediately restrict their access. The easiest way is to change the WiFi password. However, this will require reconnecting all your devices, which can be inconvenient. A more flexible method is to use Blacklist (blacklist) or Whitelist (white list) in the router settings.

In the "Wireless MAC Filtering" section, you can add the intruder's address to the blocked list. Once applied, the router will ignore connection requests from this device, even if it knows the correct password. This is an effective measure that doesn't require changing the security key.

⚠️ Attention: Be careful when enabling the "Allow only listed" (White List) mode. If you add your devices and make a mistake in one MAC address character, you'll lock yourself out and lose network access until you reset the router.

It's also recommended to enable a guest network for visitors. This will create a separate access channel with its own password, isolated from your main network, which contains computers with important data and network-attached storage (NAS). Guest access can be easily disabled at any time through the app or web interface.

Frequently Asked Questions (FAQ)

Why does the list of connected devices show more gadgets than I counted?

Modern people use a variety of gadgets: smartphones, tablets, laptops, smart TVs, watches, and speakers. Furthermore, a single physical device can create multiple network interfaces (for example, virtual Bluetooth adapters or VPN tunnels), which the router may display as separate connections. It's also worth checking whether the devices are connected via a LAN cable.

Can a neighbor guess my password?

If you have a complex password and use encryption WPA2-PSK or WPA3, it's virtually impossible to brute-force it within a reasonable time. However, if WPS (Wired Protected Setup) is enabled, attackers can exploit this protocol's vulnerability to gain access. It's recommended to disable WPS in your router's settings.

What should I do if I can't access my router settings?

Make sure you're connected to this router's network. Check the IP address in the command line. If the administrator password has been changed and forgotten, only a hard reset will help. Locate the hole on the case. Reset, press it with a paperclip for 10-15 seconds while the router is turned on. The device will reset to factory settings (the login/password will be on the sticker underneath).

Does the number of connected devices affect internet speed?

Yes, directly. The connection bandwidth is shared between all active users. If one connected device starts downloading large files or watching 4K video, the speed on other devices may drop. Furthermore, the router has a limit on the number of simultaneous connections, and if this limit is exceeded, new devices simply won't be able to connect.
