How to Check How Many Devices Are Connected to Your Wi-Fi: A Complete Guide with Instructions

Have you noticed that your internet has become slower and pages are loading slowly? One possible cause is network congestion due to a large number of connected devices. Perhaps yours Wi-Fi neighbors connected, or old gadgets remained connected after the password was updated. In this article, we'll look into all available methodsHow to find out how many people (or devices) are using your Wi-Fi—from standard router tools to advanced methods for experienced users.

Some methods are universal for all router brands, while others depend on the model and firmware. We'll cover instructions for popular brands: TP-Link, ASUS, Keenetic, MikroTik, and we'll also show you how to check connections through smartphone (Android/iOS) or computer (Windows/macOS/Linux). If you rent a place or share an internet connection with neighbors, these methods will help you manage your network load and prevent unauthorized use.

It is important to understand the difference between active And inactive Connections. Some devices (such as smart bulbs or speakers) may remain in the router's client list even if they're turned off. We'll teach you how to distinguish real traffic from "dead" connections and give tips on clearing the device list without resetting the settings.

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

The most reliable way is to log into your router's control panel. This method works on all brands, but the path to the required section may differ. You will need:

• 🌐 IP address of the router (usually 192.168.0.1 or 192.168.1.1)
• 🔑 Login and password for entry (by default, often admin/admin)
• 💻 Any device connected to this network (PC, laptop, smartphone)

Instructions for most routers:

1. Open your browser and enter your router's IP address in the address bar. If you don't know the address, look it up on the sticker on the device or run the following command in the Windows command line:

   ipconfig

   — the required address will be in the “Default gateway” line.
2. Enter your login and password. If you haven't changed them, try the standard combinations (admin/admin, admin/empty or admin/1234).
3. Go to the section with the list of connected devices. This is usually called:
   • DHCP → DHCP Clients List (on English firmware)
   • Local Network → Devices (in Russian)
   • Wireless → Wireless Statistics (for wireless clients)

In the table you will see:

• 📱 Device name (if it passes Hostname, for example, iPhone-12-Pro)
• 🔢 MAC address (unique identifier, for example, 00:1A:2B:3C:4D:5E)
• 📡 IP address (local, for example, 192.168.0.103)
• ⏱️ Connection time or activity status

2. Instructions for popular router brands

Manufacturers often change the location of partitions in firmware, but we've compiled the current paths for the latest software versions. If your interface looks different, use the settings search (usually there's a search bar at the top).

On routers ASUS And Keenetic There's a convenient "Network Map" feature that visually displays all connections, including wired devices (via LAN ports). This helps distinguish devices connected via cable from wireless clients.

3. Checking via mobile apps

Router manufacturers release official apps that simplify network management. They're perfect for quickly checking connected devices without logging into the web interface. A key benefit is notifications about new connections.

Popular apps:

• 📱 Tether (For TP-Link) - shows a list of devices indicating the traffic consumed.
• 📱 ASUS Router — there is a “Family Protection” function that blocks unknown gadgets.
• 📱 Keenetic - automatically classifies devices (e.g. "Phone", "Laptop", "Camera").
• 📱 WiFi Man (third-party) - scans the network and displays all connected devices, even without access to the router.

How to use (using example) Tether):

1. Download the app from App Store or Google Play.
2. Register or log in with your account TP-Link ID (if the router supports cloud management).
3. Select your network from the list. The app will automatically pull data from your router.
4. Go to the "Devices" or "Clients" section. Here you will see:
• 🔹 Active and inactive connections (marked "Offline")
• 🔹 Device type (according to the app database)
• 🔹 Real-time traffic consumption rate

What should I do if the app doesn't find the router?

1. Make sure your smartphone is connected to the Wi-Fi of this network.

2. Check if cloud management is enabled in the router settings (section TP-Link Cloud or similar).

3. Update your router firmware to the latest version—older versions may not support mobile apps.

Third party applications like Fing or NetScan Scan your local network and display all devices, even if you don't have access to the router. These are useful for renters or guests, but have limitations:

• ❌ Does not show connection history (only current devices).
• ❌ Devices with disabled ping response (some IoT gadgets) may not be detected.
• ❌ They don't block other people's devices - they just inform them.

4. Command line: for advanced users

If you prefer to work through the terminal, you can get a list of connected devices using standard tools. Windows, Linux or macOSThis method does not require access to the router, but will only show devices on your local network.

For Windows:

1. Open Command line (Win + R → enter cmd).
2. Run the command to scan the network:

   arp -a

   You will see a list of IP and MAC addresses of devices your PC has recently interacted with.

3. For a more complete list, use:

   for /L %i in (1,1,254) do ping -n 1 192.168.0.%i

   (replace 192.168.0 to your subnet, for example, 192.168.1).

For Linux/macOS:

1. Open Terminal.
2. Perform a network scan using nmap (need to be installed via sudo apt install nmap):

   nmap -sn 192.168.0.0/24

   This command will show all active hosts on the network with their MAC addresses and manufacturers.

Critical detail: network scanning may be blocked by your router's firewall or antivirus software. If the command returns an empty list, check your security settings.

5. How to distinguish your devices from others

You've received a list of connected gadgets—but how do you know which ones are yours and which belong to your neighbors or unknown individuals? Here's the verification process:

1. Check device names:
   • 📱 Smartphones usually have names like iPhone-14-Pro, Samsung-Galaxy-S23.
   • 💻 Laptops: MacBook-Pro, DELL-XPS-15.
   • 🎮 Consoles: PS5-1234, Xbox-Series-X.
   • 💡 Smart devices: Yeelight-78A1, Mi-Home-Device.
2. Check MAC addresses:
   • On Android: Settings → About phone → Status → Wi-Fi MAC address.
   • On iPhone: Settings → General → About → Wi-Fi Address.
   • On Windows: run in command line

     ipconfig /all

     and find the line "Physical Address".

Use inventory apps:

• 📱 Fing - shows the device manufacturer by MAC address (for example, Apple, Samsung, Xiaomi).
• 📱 NetAnalyzer — builds a graph of traffic activity for each device.

If there are devices with unknown MAC addresses in the list, check them using online services like MAC Vendors or WiresharkFor example, the address B8:27:EB:... belongs Raspberry Pi, A 78:31:C1:... — devices Apple.

6. How to block other people's devices

If you detect unwanted devices on your network, you can block them in several ways. The method you choose depends on your access rights to your router and its features.

Method 1: Blocking by MAC address (whitelist)

1. Go to the router's web interface (instructions in first section).
2. Find the section Wireless Network → MAC Filter (or Wireless MAC Filtering).
3. Select the " modeAllow only specified» (Whitelist).
4. Add MAC addresses to the list only your devices.
5. Save the settings and reboot the router.

Method 2: Change your Wi-Fi password

The simplest, but radical method:

1. In the web interface, go to Wireless Network → Security Settings.
2. Change your password to a complex one (at least 12 characters, with numbers and special characters).
3. Select encryption type WPA3-Personal (if supported) or WPA2-PSK.
4. Save and reconnect your devices.

Method 3: Hiding the network (SSID)

This won't protect against advanced users, but it will reduce the number of accidental connections:

1. In the Wi-Fi settings, find the option Hide SSID (or Hide SSID).
2. Activate it and save the settings.
3. Now the network will not be displayed in the list of available ones, but you can still connect to it if you know the name and password.

7. Traffic monitoring and detection of "parasites"

Some devices may connect to your network sporadically (for example, at night), so a one-time check isn't always effective. For ongoing monitoring, use:

Built-in router tools:

• 📊 Connection log (System Tools → Journal) - shows the login history.
• 📈 Traffic Monitor — consumption graphs by devices (available in Keenetic And ASUS).

Third-party programs:

• 🖥️ GlassWire (Windows/macOS) - Tracks which devices consume the most traffic.
• 📱 NetGuard (Android) - Blocks background traffic from unknown applications.
• 🌐 PRTG Network Monitor — a professional tool for network analysis (there is a free version).

Signs that strangers have connected to your network:

• ⚠️ A sharp drop in speed at normal times (in the evening).
• ⚠️ Unknown devices in the client list with high traffic (for example, consuming >100 Mbps).
• ⚠️ Online activity when everyone is sleeping (at night).
• ⚠️ Connection attempts with unknown MAC addresses appear in the router log.

8. Common mistakes and how to avoid them

When checking connected devices, users often encounter serious problems. We've compiled a list of the most common errors and solutions.

Error 1: The router does not show all devices

Reasons and solutions:

• 🔌 Some devices are connected via cable (LAN) — check the "Local network" or "DHCP clients" section.
• ⏳ The device is inactive but remains in the DHCP list - refresh the page or reboot the router.
• 🔄 The "Guest Network" mode is enabled in your router - check the separate list for it.

Error 2: Unknown devices reappear after blocking

This means that:

• 🔄 The attacker changed the MAC address of his device (this is easily done on Android/PK).
• 📡 A neighbor's smart device (for example, a Wi-Fi extender) connects to your network.
• 🔑 The Wi-Fi password was too simple and was hacked using brute force.

Solution: Use complex password (example: k7#pL9!vQ2$mN5) and turn it on WPA3 (if supported).

Error 3: Network scanning app can't find the router

Check:

• 📶 The device is connected to the same network as the router.
• 🔒 "Client Isolation Mode" is enabled in your router settings - disable it.
• 🛡️ Your router's firewall is blocking scanning - temporarily disable it in the section Security → Firewall.

Why are there duplicates in the device list?

It is normal for one device to have multiple network interfaces. For example:

- A laptop with Wi-Fi and Ethernet connections will be displayed twice.

- A smartphone with an enabled USB terminal (for debugging) can have two MAC addresses.

- Some IoT devices (such as smart speakers) create virtual network interfaces.

Error 4: Old devices remain connected to the network after changing the password

This happens because:

• 🔄 Devices maintain a connection cache (e.g. Windows can automatically connect to known networks).
• 📱 The "Auto-connect" option is enabled on your smartphone. Disable it in the Wi-Fi settings.
• 🔌 The router did not update the list of DHCP clients - please reboot it.

⚠️ Attention: If you use Mesh system (For example, TP-Link Deco or Google Nest WiFi), the device list may be duplicated on different nodes. In this case, check clients through the main device (usually marked in the app as "Primary Router").

FAQ: Answers to Frequently Asked Questions

Is it possible to find out how many devices are connected to Wi-Fi without access to the router?

Yes, but with limitations. You can:

• Use mobile apps like Fing or NetScan - They scan the local network and show active devices.
• IN Windows execute a command

  arp -a

  - It will display a list of IP and MAC addresses that your PC has interacted with.
• On Android (with root rights) use Termux with the team

  nmap -sn 192.168.0.0/24

  .

However, these methods will only show devices that active at the time of scanning, and will not provide information about inactive clients or those connected to another node of the Mesh system.

How do I find out who is connected to my Wi-Fi by device name?

Device names (Hostname) often contain clues:

• iPhone-..., iPad-... — devices Apple.
• Galaxy-..., SM-... - smartphones Samsung.
• Mi-..., Redmi-... - gadgets Xiaomi.
• DESKTOP-... — PC running Windows.
• esp8266, Sonoff — smart devices (sockets, sensors).

If the name is not informative (for example, android-123456), check the MAC address through services like MAC Vendors - they will show the chip manufacturer (for example, Broadcom For Apple, Qualcomm For Android).

What should I do if my router doesn't show a list of connected devices?

Possible causes and solutions:

1. Outdated firmware - update the router software in the section System Tools → Update.
2. DHCP server is disabled - check that DHCP is enabled in the local network settings (section LAN → DHCP Server).
3. Restrictions on Rights - If you are not an administrator (for example, on an office network), you may not have access to this section.
4. Hardware failure If the router overheats or resets, the client list may not update. Try resetting the settings to factory defaults.Reset button for 10 seconds).

If the problem persists, try alternative methods (mobile apps or command line).

Is it possible to find out the history of Wi-Fi connections?

It depends on the router model:

• 📅 Routers with a log (ASUS, Keenetic, MikroTik) save the connection history in the section System log or LogThere you can see the connection/disconnection time and MAC addresses.
• ⏳ Budget models (TP-Link Entry-level) usually do not keep a log - they only show current connections.
• 📊 Third-party programs like PRTG or Zabbix can keep a log if configured to monitor the network.

If your router doesn't support logging, the only way is to keep track of it manually (for example, by periodically saving screenshots of the device list).

How do I block a device by MAC address if my router doesn't support this feature?

If your router does not have MAC filtering, use the following workarounds:

1. Changing your Wi-Fi password — the simplest solution, but it will block all devices, including yours.
2. Setting up static IP:
   • Bind your devices' MAC addresses to fixed IP addresses in the section DHCP Reservation.
   • Disable the DHCP server and manually assign IP addresses only to trusted devices.
3. Using a guest network:
   • Create a separate network for other people's devices with limited speed.
   • Leave only your gadgets on the main network.

Third-party firewalls:

• Set up rules on PC with Windows Firewall or iptables (Linux) to block traffic from specific MAC addresses.

If nothing helps, consider purchasing a router with support MAC Filtering (For example, ASUS RT-AX88U or TP-Link Archer C4000).
