How to See Which Devices Are Connected to Your Wi-Fi from Your Computer: A Complete Guide

• Enter the router's IP address into the browser's address bar.
• Enter your login and password (by default it is often admin/admin or indicated on the router sticker).
• Find the section with connected devices:

  The path may vary depending on your router model. Here are examples for popular brands:

  Router manufacturer	Path to the list of devices
  TP-Link	Advanced Settings → Statistics → Wireless Mode
  ASUS	Network Map → Clients or Local Network → DHCP Server
  Keenetic	Devices → Device List
  MikroTik	IP → DHCP Server → Leases or Wireless → Registration Table

On most routers you will see:

• 🔹 Device name (if it transmits it according to the protocol mDNS or NetBIOS).
• 🔹 MAC address — unique identifier.
• 🔹 IP address (can be dynamic or static).
• 🔹 Connection type (Wi-Fi 2.4 GHz / 5 GHz / Ethernet).
• 🔹 Connection time and the volume of data transferred.

⚠️ Attention: If the list contains devices with unfamiliar MAC addresses or names (for example, android-123456), but you are not sure that these are your gadgets, we recommend temporarily disabling them using the function Blocking or Parent Control in the router. Do not block devices with MAC addresses starting with 00:00:00 or FF:FF:FF - these may be business addresses.

4. Specialized programs for monitoring Wi-Fi networks

If you need to not only view a list of devices but also monitor their activity in real time, analyze traffic, or receive notifications about new connections, it's worth using third-party programs. They offer advanced features not available in standard tools. Windows.

Top 5 programs for Wi-Fi network analysis:

• 🛡️ Wireless Network Watcher (from NirSoft) is a free utility that scans the network and displays all connected devices, indicating the manufacturer (by MAC address), IP, and time of first detection.
• 📊 Angry IP Scanner — a cross-platform scanner that checks the availability of IP addresses and ports. Supports plugins for advanced analysis.
• 🔍 Advanced IP Scanner — allows you not only to scan the network, but also to remotely control devices (for example, to shut down a PC over the network).
• 📈 GlassWire — monitors traffic in real time and shows which devices consume the most data.
• 🔒 Fing — available for both PCs and smartphones. In addition to network scanning, it can check for open ports and vulnerabilities.

Example of working with Wireless Network Watcher:

1. Download the program from official website (portable version does not require installation).
2. Launch WNetWatcher.exe (administrator rights may be required).
3. Click Start Scanning - in a few seconds you will see a full list of devices.
4. To save the report, select File → Save As.

Advantages of specialized programs:

• 🔹 Detect hidden devices that do not respond to ping.
• 🔹 Ability to customize notifications about new connections.
• 🔹 Traffic analysis by device (who "eats" the internet).
• 🔹 Export data to CSV or XML for further analysis.

5. How to identify unknown devices on the network

If you spot an unfamiliar MAC address or hostname in the list of connected devices, don't rush to block it. It might be one of your devices that wasn't automatically detected. Here's how to check:

Step 1: Check your gadgets

• 📱 On Android: go to Settings → About phone → General information → Wi-Fi MAC address.
• 🍎 On iPhone/iPad: Settings → General → About → Wi-Fi Address.
• 💻 On MacBook: System Preferences → Network → Advanced → Ethernet/Wi-Fi → MAC Address.
• 🖥️ On Smart TV or set-top boxes: usually the MAC address is indicated in the menu Network → Wi-Fi Settings.

Step 2: Use manufacturer databases

The first 6 characters of the MAC address (eg. B8:27:EB) indicate the manufacturer. Check them through:

• Website MAC Vendors Lookup.
• Team in Linux/macOS terminal:

  curl "https://api.macvendors.com/B8:27:EB"

Step 3: Analyze device behavior

If your device is actively consuming traffic (for example, downloading data), this may be a sign of:

• 🔹 A virus on one of your devices (for example, a smartphone connected to a torrent client).
• 🔹 A neighbor's device that connected to your network due to a weak password.
• 🔹 Smart device (for example, IP cameras or router in repeater mode), which you forgot to set up.

If a device seems suspicious, but you're not sure it's yours, temporarily disable it through your router and check if anything has disappeared from your network (for example, a smart light or camera has stopped working).

6. How to block unauthorized devices on a Wi-Fi network

If you detect an unauthorized device on your network, you need to block it. This can be done in two ways: through the router settings or using specialized software.

Method 1: Blocking by MAC address in the router

1. Go to the router's web interface (instructions in Section 3).
2. Find the section Security, MAC address filter or Parent Control.
3. Add the MAC address of the suspicious device to the blacklist.
4. Save the settings and reboot the router.

Method 2: Change your Wi-Fi password

If blocking by MAC address doesn't help (some devices can spoof MAC addresses), the most reliable way is to change your Wi-Fi password:

1. In the router's web interface, go to Wireless Mode → Security Settings.
2. Select encryption type WPA2-PSK or WPA3-PSK.
3. Create a complex password (at least 12 characters, with numbers and special characters).
4. Save the settings - all devices will be disconnected and will need to reconnect.

Method 3: Using a firewall (for advanced users)

If a third-party device is already connected to your network, but you want to block its access to the Internet, you can set up rules in Windows Firewall or on the router:

• 🔹 On the router: in the section Firewall Add a rule that blocks traffic for a specific IP or MAC address.
• 🔹 On PC: in Windows Firewall Create an outgoing rule that blocks connections from suspicious IP addresses.

⚠️ Attention: MAC address blocking isn't foolproof—an experienced user can change their device's MAC address. For maximum security, combine changing your Wi-Fi password with disabling this feature. WPS and enabling MAC filtering.

7. Automatic network monitoring: setting up notifications

To avoid manually checking the list of connected devices, you can set up automatic monitoring. This is especially useful for office networks or homes with a large number of smart devices.

Option 1: Setting up in the router

Some routers (eg. ASUS, Keenetic) support sending notifications about new connections:

1. In the web interface, find the section Notifications or System tools.
2. Enable the option Send notifications by email or Push notifications.
3. Enter your email or link your account Telegram/Slack (if supported).
4. Enable the option Notify about new devices on the network.

Option 2: Programs with a monitoring function

Programs like GlassWire or Fingbox (for routers) allow:

• 🔹 Receive notifications about new devices on the network.
• 🔹 Monitor unusual activity (such as traffic spikes).
• 🔹 Block suspicious devices automatically.

Option 3: Script for automatic scanning (for IT specialists)

If you are familiar with PowerShell or Bash, you can write a script that will scan the network and send a report to email. An example of a simple script for Windows:

$devices = arp -a | Select-String "dynamic"
$devices | Out-File -FilePath "C:\network_scan\devices_$(Get-Date -Format 'yyyy-MM-dd').txt"

To automate the launch, add a script to Windows Task Scheduler with a frequency of, for example, once an hour.

8. Common errors and problems when checking devices

Users often encounter difficulties when trying to view the list of connected devices. Let's look at common issues and their solutions:

Problem 1: Team arp -a shows few devices

Solution: The ARP cache stores data only about devices your PC has recently interacted with. To update the cache:

1. Do it arp -d (clear cache).
2. Scan the network with the command ping (as in Section 2).
3. Repeat arp -a.

Problem 2: I can't access the router's web interface.

Possible reasons:

• 🔹 Incorrect router IP address (check via ipconfig).
• 🔹 The router is not responding (reboot it with the button) Reset on the back panel).
• 🔹 Your firewall or antivirus is blocking access (temporarily disable them).
• 🔹 The router's IP address has changed (try 192.168.0.1, 192.168.1.1, 192.168.8.1).

Issue 3: Ghost gadgets appear in the device list

Sometimes devices that have been offline for a long time may appear in the list. This is due to:

• 🔹 Caching data in the router (reboot it).
• 🔹 Statically assigned IP addresses (check settings DHCP reservations).
• 🔹 Devices in sleep mode (some routers keep them in the list until the IP lease expires).

Problem 4: Network scanning programs do not work

Solution:

• 🔹 Run the program as administrator.
• 🔹 Temporarily disable your firewall and antivirus.
• 🔹 Check that your PC is connected to the network via Wi-Fi, not Ethernet (some programs only scan the current adapter).

⚠️ Attention: If, after all these steps, unknown devices remain on the network and changing the password doesn't help, your router may be compromised (for example, through a firmware vulnerability). In this case, we recommend resetting the router to factory settings (Reset) and update the firmware to the latest version.
