Who's connected to my D-Link Wi-Fi router? Check in 30 seconds.

To use the application:

• 📱 Download D-Link Wi-Fi from App Store or Google Play (Free, no extra fluff). Make sure your router model is supported—the list of compatible devices is in the app description.
• 🔗 Connect your smartphone to the router's network (Wi-Fi or via a cable with an adapter). The app will automatically find your D-Link in the local network.
• 🔑 Enter your control panel login and password (the same as for the web interface).
• 📊 Go to the section Devices (Devices) or Net (Network). A list of all connected gadgets with their names will be displayed here, MAC addresses and connection type.

The app also shows traffic usage graph by device, which will help identify bandwidth-hungry devices. For example, if an unknown device consumes 80% of the bandwidth, this is a clear sign of an unauthorized connection. Newer versions of the app include this feature. Guest network, which allows you to isolate suspicious devices from the main network.

3. Checking via the command line (for advanced users)

If you have access to a computer running Windows, macOS or LinuxYou can scan your local network using standard network utilities. This method doesn't require access to the router's control panel, but it will only show currently active devices.

For Windows follow these steps:

1. Open Command line (Win + R → enter cmd → Enter).
2. Enter the command to view ARP tables (list of IP and MAC addresses of devices with which your PC communicated):

   arp -a

   As a result, you will see a list like this:

   192.168.0.1 ff-ff-ff-ff-ff-ff dynamic
   192.168.0.100 00-1a-2b-3c-4d-5e dynamic

3. To get a more complete list, first ping the entire local network range (for example, if your router issues an IP from 192.168.0.1 to 192.168.0.254):

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

   Then re-run arp -a — now the table will contain all the devices that responded.

For macOS/Linux use the command:

nmap -sn 192.168.0.0/24

It will scan the network and list hosts with MAC addresses and names (if available). Utility nmap may not be installed by default - it needs to be installed via the package manager (brew install nmap for macOS or sudo apt install nmap for Linux).

⚠️ Attention: Some devices (such as smartphones in power saving mode) may not respond to ping requests and may not appear in ARP tableFor a full scan, use specialized programs like Advanced IP Scanner or Angry IP Scanner.

4. Third-party network monitoring programs

If the router's built-in tools or command line seem insufficient, you can use third-party utilities. They offer advanced features: real-time traffic monitoring, notifications about new devices, scheduled blocking, and even geolocation of connected devices (based on a database). MAC addresses).

Here are the top 3 programs for different platforms:

Example of working with Fing:

1. Install the application and open it.
2. Click Scan — the program will automatically detect your network.
3. After 10-20 seconds, you will see a list of devices indicating:
   • 📱 Name (if available).
   • 🔗 MAC addresses and the manufacturer.
   • 📡 Wi-Fi signal (for wireless devices).
   • ⚡ Traffic consumption (in the premium version).

⚠️ Attention: Some antiviruses (for example, Kaspersky or ESET) may block network scanning, interpreting it as an attack. Disable network protection in your antivirus settings while scanning.

Write down its MAC address and name (if any)

Check if it belongs to your guests or IoT gadgets

Try disabling it through the router control panel.

Change your Wi-Fi password if you have too many connections

Enable MAC address filtering-->

5. How to block other people's devices on a D-Link router

Found a strange device on your network? Don't rush to change your Wi-Fi password—you can first block just that device by MAC addressThis is convenient if you don't want to disconnect all users (for example, in an office or a large family). Here's how:

1. Log in to the router control panel (instructions in Section 1).
2. Go to Advanced settings (Advanced) → Security (Security) → MAC address filtering (MAC Filtering).
3. Enable filtering by selecting the option Allow only specified (Allow Only Listed) or Block specified (Deny Listed).
4. Add MAC address Add the unwanted device to the list and save the settings. Example address: 00:1A:2B:3C:4D:5E.
5. Restart your router for the changes to take effect.

If filtering by MAC If this doesn't work (some devices can spoof addresses), use alternative methods:

• 🔒 Change your Wi-Fi password complex (at least 12 characters, with numbers and special characters). Use generators like LastPass or 1Password.
• 🔄 Disable WPS — this function is easy to hack even without a password. Find the option in the section Wi-Fi Protected Setup and deactivate it.
• 🛡️ Enable guest network For temporary users (guests, smart devices). It is isolated from the main network and has a separate password.

For models D-Link with support 802.11ac (For example, DIR-882 or DIR-1960) the function is available Temporary access (Schedule). It allows you to restrict Wi-Fi access according to a schedule—for example, turning off the internet at night when everyone is asleep, thereby blocking unauthorized connections.

6. Hidden Connections: How to Find Invisible Devices

Sometimes the list of connected devices doesn't show all gadgets. This can happen for several reasons:

• 🕵️ The device is connected but inactive (for example, a smartphone in sleep mode).
• 🔌 The gadget uses a static IP not obtained via DHCP.
• 👻 Hacker software disguises its presence on the network.

To identify such connections, use one of the methods:

1. View DHCP clients:
   • In the router control panel, go to LAN → DHCP Server → DHCP Clients List.
   • This will display all devices that the router has assigned an IP address to, even if they are currently turned off.
2. Router log analysis:
   • In the section System tools (System Tools) find Logs (Logs).
   • Search for posts with Associated (connected) or Disassociated (disabled). Example line:

     [Wi-Fi] STA 00:1A:2B:3C:4D:5E Associated

6. Port scanning:
   • Use the program Zenmap (graphic version nmap) to scan the local network for open ports.
   • Unexpected open ports (eg. 22, 3389) may indicate the connection of hacker tools.

If you detect suspicious activity (for example, a device with MAC address manufacturer TP-Link, although you don’t have such gadgets), we recommend:

• 🔍 Check your router for malware using D-Link Firmware Checker (available on the official website).
• 🔄 Update your router firmware to the latest version (in the section System tools → Software update).
• 🛡️ Install an antivirus with network protection on all your devices (for example, Bitdefender Total Security).

7. Prevention: How to protect Wi-Fi from unauthorized access

The best way to combat unauthorized connections is to prevent them. Here's a checklist for setting up your router. D-Link For maximum safety:

Use WPA3 encryption (or WPA2 if WPA3 is not supported)

Disable SSID broadcast (hide network name)

Enable MAC address filtering for known devices

Update your router firmware to the latest version

Disable Remote Management

Change the default IP address of the router (for example, to 192.168.10.1)-->

Additional protective measures:

• 🔐 Change your Wi-Fi password regularly (Once every 3-6 months). Use password managers to generate complex combinations.
• 📡 Set up a separate guest network for friends and smart devices. Limit its speed and access to local resources (printers, network drives).
• 🕒 Use a Wi-Fi schedule, if the Internet is needed only during certain hours (for example, from 7:00 to 23:00).
• 🔄 Enable automatic firmware updates (if available). This closes vulnerabilities that hackers could exploit.

For models D-Link with support AiProtection (For example, DIR-X1560) additional functions are available:

• 🛡️ Defense against attacks: blocking password guessing attempts, protection from ARP-spoofing.
• 📊 Traffic monitoring: alerts about suspicious activity (for example, downloading torrents by an unknown device).
• 👤 Parental control: restricting access to certain websites for individual devices.

If your router does not support modern security protocols (for example, an outdated model DIR-300), consider upgrading. New routers D-Link (series EXO or COVR) are equipped with a built-in antivirus and intrusion detection system (IDS).
