Who's connected to my Wi-Fi? How to see a list of devices on the network in 5 minutes

Do you suspect someone is accessing your Wi-Fi? Has your internet speed suddenly dropped, and is your data draining out of control? Checking the list of connected devices — the first step to solving the problem. In this article, we'll cover all the working methods for finding out who's using your network: from standard router tools to mobile apps and the command line.

It doesn't matter what kind of router you have - TP-Link, ASUS, Keenetic or MikroTik — the verification principles are the same. And if you rent an apartment or live in a dorm, these methods will help you identify the "freeloaders" hogging your bandwidth. The key is to act systematically and not miss a single suspicious device.

But before you block everyone, make sure the problem is truly caused by unrelated connections. Sometimes lag and low speeds are caused by an overloaded router, outdated firmware, or issues with your ISP. Check your network first — it might not be your neighbor's fault, but your own smartphone, which is downloading updates in the background.

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

Any modern router keeps a log of connected devices. To view it, go to admin panel via a browser. The login address is usually located on a sticker on the back of the device (e.g. 192.168.0.1 or 192.168.1.1). The default login and password are often admin/admin or admin/password.

After logging in, look for a section with a name like:

• 🔍 DHCP clients (list of devices to which the router automatically assigned an IP)
• 📱 "Wireless Network" → "Client List" (active Wi-Fi connections)
• 🌐 "Local Network" → "Devices" (all gadgets, including those connected via cable)

In the table you will see:

• 🖥️ IP address devices (for example, 192.168.0.103)
• 📌 MAC address (a unique identifier that can be used to determine the gadget model)
• 🕒 Connection time (helps to identify "guests" who sit at night)
• 📶 Host name (sometimes the phone or laptop model is displayed)

If there are unknown devices in the list, don't rush to block themFirst, check:

⚠️ Attention: Some routers list not only active devices but also recently connected devices (for example, within the last 24 hours). Check this in the settings or reboot the router to see only current connections.

2. How to determine the device model by MAC address

A MAC address is like a gadget's "passport." The first 6 characters (for example, B8:27:EB) indicate the manufacturer. To find out whose device it is, use free services:

• 🔗 MAC Vendors Lookup (Enter the address and the service will show the brand)
• 🔗 Arul John’s MAC Address Lookup (more detailed database)

Examples of transcription:

If the service showed Xiaomi, and you don't have devices of this brand—this is cause for concern. But remember: MAC addresses can be spoofed (spoofing), so this method does not provide 100% guarantee.

By the way, in some routers (for example, ASUS RT-AX88U) has a built-in device traffic analysis. It shows not only the device model but also how much data each device consumes.

3. Mobile apps for Wi-Fi monitoring

If you're too lazy to dig into your router settings, use smartphone apps. They scan your network and display all connected devices. Popular options include:

• 📱 Fing (Android/iOS) — identifies device models, checks ports, tests speed.
• 📱 WiFi Analyzer (Android) - shows channels, signal strength and a list of clients.
• 📱 NetScan (iOS) - scans the local network and saves connection history.

How to use (using example) Fing):

1. Connect to your Wi-Fi network.
2. Launch the app and click "Scan".
3. Wait for the verification to complete (it will take 10–30 seconds).
4. Browse the list of devices - the application will automatically detect the manufacturer.

Advantages of mobile applications:

• ✅ No need to go into router settings.
• ✅ You can check the network remotely (if the router supports cloud management).
• ✅ Some apps notify you about new connections.

But there are also disadvantages:

⚠️ Attention: Apps only see devices that are active at the time of scanning. If a "guest" connects overnight and then disconnects, you won't notice. For complete control, it's best to combine this method with checking the router logs.

4. Checking via the command line (for Windows and macOS)

If you prefer "manual" methods, you can use command lineThis method works on PCs and laptops connected to the same network.

For Windows:

1. Click Win + R, enter cmd and press Enter.
2. Enter the command:

   arp -a

   It will show the ARP table (IP to MAC address mapping).

3. Compare the IP addresses with those issued by the router (from the first method).

For macOS/Linux:

1. Open Terminal.
2. Enter:

   nmap -sn 192.168.0.0/24

   (replace 192.168.0.0 to your subnet, if it is different).

3. Wait for the results - the program will show all active hosts.

These commands will give you raw data. To decrypt it, you'll have to manually Google MAC addresses or use scripts. For example, on Linux, you can install macchanger for analysis.

A critical detail: if your network uses IPv6, the arp -a command may not show all devices. In this case, it's better to use specialized utilities like Wireshark.

How to find your subnet for the nmap command

Open Terminal and type ifconfig (macOS/Linux) or ipconfig (Windows) Look for the line inet with an address of the type 192.168.x.x — this is your subnet. For example, if IP 192.168.1.100, then the subnet is 192.168.1.0/24

5. How to identify a "freeloader" by their online behavior

Even if you find an unknown device, how can you tell it's definitely not yours? Pay attention to:

• 🕒 Activity time: If the gadget appears at night or in your absence, it’s suspicious.
• 📊 Traffic consumptionSome routers display how much data each device is using. If an unknown device is downloading 10 GB a day, that's a clear sign.
• 🔄 Connection frequency: If the MAC address appears and then disappears, it may be a neighbor who connects from time to time.

In routers Keenetic And ASUS There are built-in traffic monitoring tools. For example, in Keenetic go to: Statistics → Traffic → By Device

Here you will see graphs of consumption per day/week/month.

If your router doesn't support detailed statistics, you can use third-party programs:

• 🖥️ GlassWire (Windows/macOS) - shows which programs are consuming traffic.
• 📊 NetWorx — keeps a log of internet usage by device.

What should you do if you're sure someone else has connected to your Wi-Fi? Blocking — isn't always the best solution. Sometimes it's enough:

⚠️ Attention: If you live in an apartment building and a neighbor accidentally connects to your network (for example, because they have the same SSID), try changing the Wi-Fi name and password first. They might not even know they're using your channel.

6. How to block an unknown device

If you've identified an "intruder," there are several ways to disable it:

Method 1: Blocking by MAC address

1. Go to your router settings (as in the first method).
2. Find the section MAC Address Filtering or Access Control.
3. Add unknown MAC to blacklist.
4. Save the settings and reboot the router.

Method 2: Change your Wi-Fi password

The simplest and most effective method:

1. In the router panel, 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 WPA2-PSK or WPA3 (if supported).
4. Save and reconnect your devices.

Method 3: Hiding the network (SSID)

This won't protect you from experienced hackers, 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 changes.
3. Now your network will not be displayed in the list of available ones, but you can still connect to it if you know the name.

After blocking, check the network again in 10-15 minutes. If the unknown device disappears, the problem is solved. If not, you may have a more serious vulnerability (for example, your router is infected with malware).

7. Additional security measures

To minimize the risk of unauthorized access, follow these tips:

• 🔐 Disable WPS - This feature makes connection easier, but it is easy to hack.
• 🔄 Enable guest network For friends, it is isolated from the main one and does not provide access to local devices.
• 📡 Reduce signal strength, if your router supports this feature. This will reduce your Wi-Fi "blur" outside your apartment.
• 🔍 Set up notifications about new connections (if the router supports it).

For advanced users:

• 🛡️ Configure a firewall on the router to block suspicious requests.
• 🔗 Use a VPN for your router (for example, through DD-WRT or OpenWRT).
• ⏱️ Activate the Wi-Fi schedule (for example, turning off the Internet at night).

If you frequently encounter connections from strangers, consider purchasing a router that supports AI defenses (For example, ASUS AiProtection or TP-Link HomeCare). These systems automatically block suspicious activity.

FAQ: Frequently asked questions about connected devices

Is it possible to find out who is connected to Wi-Fi without logging into the router?

Yes, using mobile apps (eg. Fing or NetScan) or command line (commands arp -a or nmap). However, these methods will only show active devices, unlike router logs, which show the connection history.

What should I do if my device list contains many unknown gadgets with Cyrillic names?

These are most likely devices from your provider (for example, an IPTV set-top box or a telephony module). Check your contract or call support—they can tell you which devices should be connected by default. They could also be smart gadgets (lamps, sockets) that you forgot to configure.

Is it possible to track the physical location of a device on my network?

It's impossible to pinpoint your location, but you can roughly estimate the distance based on your signal strength (RSSI). For this, use apps like WiFi Analyzer (Clients tab). The weaker the signal (for example, -80 dBm), the further away the device is. However, this method only works for devices connected via Wi-Fi and does not provide precise coordinates.

Why does the unknown device reappear after changing the password?

Possible reasons:

• 🔄 The password is saved on the device (for example, in the TV or printer settings).
• 🕵️ Someone has physical access to your router and resets the settings.
• 🦠 The router is infected with malware that opens a "back door".

Solution: Reset your router to factory settings (hard reset), update the firmware and set everything up again.

Can my neighbor connect to my Wi-Fi if I hide the SSID?

Yes. Hiding the network name (SSID) does not protect against connection—it's merely a cosmetic measure. An experienced user can connect with the network name and password. For true protection, use WPA3, turn it off WPS and change your password regularly.
