How to See How Many Devices Are Connected to Your Wi-Fi: A Complete Guide (2026)

Have you ever noticed that your internet suddenly starts to slow down, even though you haven't changed your data plan? One possible cause is network congestion due to too many connected devices. Perhaps yours Wi-Fi neighbors connected, or old gadgets remained online after a router update. In this article, we'll look into all available verification methods, including hidden router features, mobile apps, and even a command line for advanced users.

It's important not only to identify "extra" devices, but also to understand how they impact the speed and security of your network. For example, Budget routers (up to 3,000 ₽) often limit the stable operation of 10–15 devices simultaneously, and each additional device can reduce speed by 5-15%. We'll also tell you how to disable unwanted "guests" and optimize network load.

Why is it important to monitor the number of devices on Wi-Fi?

Many users aren't even aware that their network may be overloaded. Here are three key reasons why it's important to regularly check your connected devices:

• 📉 Speed ​​dropEach device uses up some of your bandwidth. For example, a smartphone might be downloading updates in the background, or a smart speaker might be streaming music even when you're not using it.
• 🔒 Data leak: Third-party devices can intercept your traffic (especially if the network is not secure) WPA3). This is a risk of password or banking data leakage.
• 💡 Inefficient use of resources: Old devices (eg. printers or IP cameras) can continuously send requests to the network, even in standby mode.

According to the study Kaspersky By 2023, at least one unauthorized connection was detected in 40% of home networks. Most often, these are neighbors' devices that connected by mistake (for example, to a network with a similar name) or intentionally—if the password is too simple.

Method 1: Checking via the router's web interface

The most reliable and accurate method is to access your router settings. These instructions apply to most models: TP-Link, ASUS, Keenetic, Zyxel, MikroTik and others. The main thing is to know your router's IP address and login information.

1. Open your browser and type in the address bar 192.168.0.1 or 192.168.1.1 (if it doesn't fit, check the sticker on the back of the router).
2. Enter your login and password (by default it is often admin/admin or admin/password).
3. Go to the section with the device list. The paths may vary:
   • 🔹 TP-Link: Basic → Network Map or DHCP → DHCP Clients List
   • 🔹 ASUS: Network Map → Devices
   • 🔹 Keenetic: Devices → Device List

In the table you will see:

⚠️ Attention: If the list contains devices with unfamiliar names (for example, android-123456 or Unknown) is a cause for concern. But first, check whether they belong to your guests or smart gadgets (lamps, outlets, vacuum cleaners).

Check the MAC address using Google search (sometimes you can determine the model)

Disconnect the device from the network temporarily and observe the reaction.

Method 2: Mobile apps for network monitoring

If you're too lazy to access your router settings or your router is too complex, you can use dedicated apps. They scan your network and display all connected devices. Here are the top three proven tools:

• 📱 Fing (iOS/Android) — the most popular app with a simple interface. It displays not only the number of devices but also their manufacturers (by MAC address) and open ports.
• 📱 WiFi Analyzer (Android) — in addition to the list of devices, it analyzes channel load and helps you choose the optimal one for your router.
• 📱 NetScan (iOS) - suitable for advanced users, can save scan history and compare changes.

How to use (using example) Fing):

1. Install the application and open it.
2. Click "Scan" and the program will automatically detect your network.
3. After 10-20 seconds, you will see a list of devices indicating their types (smartphone, TV, printer, etc.).

The advantage of apps is that they work even if you don't have access to the router (for example, when visiting or at the office). However, they don't always show exact device name — only the manufacturer by MAC address.

Method 3: Command Prompt (for Windows)

If you prefer "classic" methods, you can use built-in tools WindowsThis method does not require installing additional programs, but it does require some technical skills.

Open Command line (Win + R → enter cmd → Enter) and run the command:

arp -a

You'll see a table with the IP and MAC addresses of all devices that have recently interacted with your computer. For a more complete list, first send ping to the broadcast address of your network (for example, 192.168.0.255), and then run it again arp -a.

⚠️ AttentionThis method will only show devices that have been actively communicating with your PC in the last few minutes. "Sleeping" devices (such as powered-off smartphones) may not be displayed.

For a more detailed analysis, you can use the command:

net view

It will show devices on the local network, but it does not work in all versions. Windows (depending on network discovery settings).

Method 4: Special programs for PC

If the command line seems too complicated, you can use free network scanning programs. They offer more features than mobile apps and often have advanced functions (such as device blocking).

Example of working with Advanced IP Scanner:

1. Download and install the program from the official website.
2. Start scanning (Scan button).
3. In a few seconds you will receive a list of all devices with IP, MAC addresses and names (if available).
4. Right-click on a suspicious device to block it (if your router supports this feature).

How to block a device through a router

1. Find its MAC address in the list of connected gadgets.

2. Go to the router settings section Wireless → MAC Filter (or similar).

3. Add the MAC address to the blacklist and save the settings.

4. The device will automatically turn off when you try to connect.

Method 5: Checking via smart speakers and voice assistants

If you have smart speaker (For example, Yandex Station, Google Nest or Amazon Echo), it can also help with network monitoring. Voice assistants are often integrated with routers and can display a list of devices.

Example commands:

• 🎤 «Alice"Show me the devices on my network" (for speakers) Yandex with support Yandex.Router).
• 🎤 «Okay, Google."How many devices are connected to my Wi-Fi?" (if the speaker is connected to Google Wi-Fi).

This method is the simplest, but it does not work with all router models. For example, Yandex.Router supports this function, and TP-Link Archer C6 — No. Also, voice assistants usually don't show MAC addresses, which makes it difficult to identify unknown devices.

How to reduce Wi-Fi load if there are too many devices

If you find yourself with more than 20 devices connected to your network, here are a few ways to optimize it:

• 🔄 Divide the networksCreate a separate network for guests (in your router settings) with a speed limit. This will prevent your main devices from being overloaded.
• ⏳ Set up a schedule: Turn off Wi-Fi on smart devices (eg. robot vacuum cleaner or coffee maker) at night, when no one is using them.
• 📡 Update your router: If your model is older than 5 years, it may not be able to handle modern workloads. Routers with support Wi-Fi 6 (For example, ASUS RT-AX88U) better distribute traffic between multiple devices.
• 🔒 Enable QoS: Function Quality of Service In the router settings, you can prioritize traffic (for example, give maximum speed to your smartphone instead of a smart light bulb).

It's also worth checking if there are any devices connected to your network that haven't been used for a long time. For example, an old laptop, lying in the closet, or fitness bracelet, which you no longer wear. They can be safely removed from the list of connected gadgets.

Common mistakes and how to avoid them

When checking devices online, many users make common mistakes that lead to false conclusions. Here are the most common:

1. Ignoring "sleeping" devices: For example, MacBook In sleep mode, it may remain online but not be visible in some scanners. To see it, wake up the device or use ping.
2. IPv6 ConfusionSome routers show the same device twice—as both IPv4 and IPv6. This is normal and does not indicate duplication.
3. MAC address misinterpretation: The first 6 characters of the MAC address indicate the manufacturer (e.g. B8:27:EB — Raspberry Pi). But this doesn't always help identify the device, as many Chinese gadgets use "gray" MAC addresses.

Another common problem is unupdated router firmwareOutdated software may display the device list incorrectly or not show some connections at all. Solution:

1. Check the firmware version in the router settings (section System Tools → Firmware Upgrade).
2. Download the latest version from the manufacturer's official website.
3. Update the firmware (do not turn off the router during the process!).

⚠️ Attention: If after updating the firmware the router starts to work unstably (for example, Wi-Fi disappears), perform a factory reset (button Reset on the back panel). This will solve the problem in 90% of cases.

FAQ: Answers to frequently asked questions

Is it possible to find out which websites a device is visiting on my network?

Yes, but this requires special tools, for example, Wireshark (for advanced users) or routers with the function Traffic Monitor (For example, Keenetic). However, tracking other devices' traffic may violate privacy laws if you don't own those devices.

Why do unknown gadgets with names like "Direct-TV" appear in the list of devices?

These could be:

• Your neighbors' smart TVs that have connected to your network by mistake (if you have a weak password).
• Devices of the type Chromecast or Apple TV, who are looking for networks for streaming.
• Viruses on one of your devices that create "phantom" connections (check your gadgets with an antivirus).

What is the maximum number of devices that can be connected to one router?

The theoretical limit is 254 devices (due to protocol peculiarities DHCP). However, in practice:

• Budget routers (TP-Link TL-WR840N) work stably with 10–15 devices.
• Middle segment (ASUS RT-AC68U) — up to 30–50 devices.
• Flagships (Netgear Nighthawk RAX200) - 100+ devices thanks to Wi-Fi 6 and a powerful processor.

When the limit is exceeded, the speed drops due to overload of the router's processor.

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

The exact location cannot be determined, but you can roughly estimate the distance to the router based on the signal level (in dBm). To do this:

1. Use the app WiFi Analyzer (Android) or NetSpot (Windows/macOS).
2. Find the device in the list and look at the value RSSI:
• -30 dBm - a device next to the router.
• -60 dBm - in another room.
• -90 dBm - at the edge of the coverage area or behind a wall.

If the signal is weak, but the device is active, it may be a neighbor connecting to your network.

How to protect your network from unauthorized connections?

Here is a minimum set of measures:

1. Change your default Wi-Fi password to a complex one (at least 12 characters, with numbers and special characters).
2. Turn it off WPS (This is a vulnerable protocol that can be easily hacked).
3. Turn on WPA3 instead of WPA2 (if the router supports it).
4. Hide network name (SSID) is pointless - it doesn't protect against hacking, but only complicates the connection of legitimate devices.
5. Set up MAC filtering (but remember that MAC addresses can be spoofed).
