How to See Which Devices Are Connected to My Wi-Fi on an Android Phone: A Complete Guide

Do you suspect that someone else is using your Wi-Fi? Or do you just want to control which devices are using your internet? Smartphone on Android can become a powerful tool for monitoring your home network—without having to connect to the router via a computer. In this article, we'll explore all available methods: from built-in functions Android to specialized applications that will show not only a list of devices, but also their activity, IP addresses, and even models.

Many users mistakenly believe that access to the router's admin panel is required to check connected devices. In fact, Most modern smartphones running Android 10+ can scan a local network without a router password., using standard protocols ARP or PingHowever, there are some nuances: some methods require superuser rights (root), while others only work with certain firmware versions. We'll examine each option in detail so you can choose the best one for your situation.

Before you begin checking, make sure your phone is connected to the same Wi-Fi network you want to scan. This is a requirement for all the methods described below. Also note: some routers (especially from providers like Rostelecom or Beeline) may block network scanning by third-party devices - in this case, only access to the router's web interface will help.

1. Android's Built-in Tools: Browse the Network Without Apps

Starting from Android 9 PieThe system has integrated basic functions for local network analysis. While they won't display a complete list of devices like specialized utilities, they will help identify the most active devices. Here's how to use them:

Open Settings → Network & Internet → Wi-FiTap on your network name (not the switch!). In the window that opens, select Network management or Additionally (The name of the item depends on the firmware). A section may be displayed here Connected devices — it contains a list of gadgets that have recently exchanged data with the router.

This method has significant limitations:

• 🔹 Shows only active devices (those that have transmitted data in the last 5-10 minutes). Sleeping gadgets (for example, smart bulbs that are turned off) will not be displayed.
• 🔹 No information about IP-addresses, MAC-addresses or models of devices - only their names (which can be faked).
• 🔹 On some firmware (for example, MIUI from Xiaomi or ColorOS from Oppo) this section may be missing or require additional permissions.

If in your version Android If there's no such section, don't worry—that's normal. Manufacturers often simplify the interface by removing unnecessary features. In this case, proceed to the next method.

2. Network Scanning Applications: TOP-5 Utilities

Specialized applications from Google Play Offer much more functionality: from displaying a complete list of devices to blocking suspicious devices. We've tested dozens of programs and selected the best in terms of functionality and security.

Here are the key criteria we used to evaluate the utilities:

• 🛡️ Security: no requests for access to SMS, contacts or geolocation (such permissions are not needed for network scanning!).
• 📊 Detailing: display MAC-addresses, device manufacturers, connection history.
• 🚀 Speed ​​of work: time for a full network scan (ideally less than 10 seconds).
• 💰 Monetization: no hidden fees for basic features.

For most users we recommend Fing or Network AnalyzerThey combine ease of use with deep analytics. For example, Fing can not only display a list of devices, but also scan them for vulnerabilities (such as open ports that hackers can exploit).

Make sure the app has over 1 million downloads and a rating above 4.0|

Check permissions (there should be no access to SMS or calls)|

Install only from the official Google Play-->

Important: Some applications (eg. IP Tools) may request root rights for advanced features. They will work without them, but with limitations. If you're not ready to root, choose utilities that don't require it (like Fing).

3. Manual scanning via terminal (for advanced users)

If you prefer to do without third-party applications, you can scan the network manually via Android terminalThis method requires knowledge of basic commands, but gives you full control over the process. You'll need any terminal application, such as Termux (available in Google Play And F-Droid).

Here are the step-by-step instructions:

1. Install Termux and open it.
2. Enter the command to install the required packages:

   pkg install nmap

3. Find out your local IP address (you will need it for scanning):

   ifconfig

   Look for a line like this inet 192.168.x.x (usually in the section wlan0).

4. Run a network scan (replace 192.168.1.0/24 to your subnet):

   nmap -sn 192.168.1.0/24

After a few seconds, the terminal will display a list of all devices on the network with their IP And MAC-addresses. Example output:

Nmap scan report for 192.168.1.1
Host is up (0.045s latency).
MAC Address: AA:BB:CC:DD:EE:FF (TP-Link Technologies)

Nmap scan report for 192.168.1.100
Host is up (0.002s latency).
MAC Address: 11:22:33:44:55:66 (Samsung Electronics)

By MAC-the address can be used to identify the device manufacturer. For example, the prefix AA:BB:CC belongs TP-Link, A 11:22:33 — SamsungA full list of prefixes can be found on the website. IEEE (organization distributing MAC-addresses).

How to decipher a MAC address?

The first 6 characters (3 bytes) of a MAC address are called the OUI (Organizationally Unique Identifier) ​​and are assigned by the manufacturer. For example:

- B8:27:EB — Raspberry Pi

- 78:31:C1 — Apple (iPhone/iPad)

- 00:1A:79 — Sony (PlayStation)

The remaining symbols are unique to each device.

This method is the most accurate, but it takes time to set up. Also, some routers block ICMP-packets (used for ping), which may prevent some devices from being displayed. In this case, scanning via ARP-table:

cat /proc/net/arp

4. Checking via the router's web interface

If the previous methods didn't provide a complete picture, the most reliable way is to log into the router's admin panel. It displays all connected devices, including those in sleep mode. The instructions are universal for most routers (TP-Link, Asus, Keenetic, MikroTik and others).

Steps to log in:

1. Find out IP- your router's address. Usually it's 192.168.0.1, 192.168.1.1 or 192.168.8.1The exact address can be found on the sticker on the back of the device.
2. Enter this address into the address bar of your phone's browser (connected to Wi-Fi).
3. Enter your login and password. By default, this is often admin/admin or admin/passwordIf you changed them, use your data.

The interface below may vary depending on your router model. Look for sections with the following names:

• 📋 DHCP Clients List (List of DHCP clients)
• 🖥️ Connected Devices (Connected devices)
• 🌐 Network Map (Network map)
• 🔌 LAN or Wireless

Interface example TP-Link:

Here you will see:

• 🔢 IP address each device
• 🖧 MAC address (unique identifier)
• 📱 Device name (if assigned)
• ⏱️ Connection time
• 📶 Connection type (Wi-Fi or cable)

In most routers you can do this here block suspicious device by MAC-address or change the Wi-Fi password. For example, in Keenetic this is done in the section Home Network → Devices → Block.

⚠️ Attention: Some providers (eg MTS or Beeline) block access to router settings if it's rented. In this case, contact support or use the alternative methods in this article.

5. Traffic analysis: who is consuming your internet?

Not only a list of connected devices but also traffic analysis helps detect "outsiders" on the network. If a device is consuming a suspicious amount of data (for example, 10 GB in an hour), this could be a sign of hacking or that your Wi-Fi is being used for mining, torrents, etc.

The following are suitable for traffic monitoring:

• 📊 Built-in router tools: in the admin panel, look for the section Traffic Monitor or BanditFor example, in Asus This Traffic analysis.
• 📱 Applications: GlassWire (shows traffic by device), Data Usage Monitor (monitors consumption in real time).
• 🖥️ PC utilities: Wireshark (for deep packet analysis, requires skills).

Sample report from GlassWire:

Please note:

• 📈 Sudden traffic surges during non-working hours (at night).
• 🌍 Suspicious geolocations: if the traffic goes to servers in China or the USA, and you don’t use them.
• ⚡ High ping to certain devices (may indicate a DDoS attack).

If you find any anomalies:

1. Check it out MAC-address of the suspicious device via ARP-scanning.
2. Try disconnecting it from the network (change the Wi-Fi password or block it MAC in the router).
3. If the traffic continues, your router may be infected with malware. A factory reset may help.

6. How to detect hidden devices (IoT, smart home)

Modern homes are filled with smart gadgets: cameras, light bulbs, outlets, speakers. Many of them connect to Wi-Fi, but they don't always show up in standard network scanners. For example, a camera Xiaomi Mi Home can use the protocol MQTT and not answer ping-requests.

To find such devices:

1. Use specialized IoT scanners, such as IoT Scanner or Thingful.
2. Check the list ARP-cache in the router (via terminal or web interface).
3. Disconnect all known devices from the network and see which ones IP-addresses remained active.

Typical signs of IoT devices on the network:

• 🔌 Unusual hostnames: esp8266, sonoff, tuyasmart.
• 📡 Constant exchange of packets with cloud servers (for example, aws.amazon.com For Alexa).
• 🔄 Regular scheduled connections (for example, smart plant watering).

If you detect an unknown IoT device:

⚠️ Attention: Some "smart" gadgets (especially cheap ones with AliExpress) may have vulnerabilities that allow hackers to penetrate your network. If you don't recognize the device, it's best to disconnect it from Wi-Fi and check for firmware updates.

To manage IoT devices, we recommend:

• 🔒 Create for them separate guest network in the router (this will limit their access to other gadgets).
• 🔄 Update firmware regularly (via the manufacturer's official apps).
• 🚫 Disable unnecessary features (for example, remote access from the Internet).

7. Security: How to protect your Wi-Fi from strangers

Detecting thieves is half the battle. Preventing reconnections is also crucial. Here are some proven protection methods:

Basic router settings:

• 🔐 Change your Wi-Fi password to a complex one (at least 12 characters, with numbers and special characters). An example of a good password: Wifi@Home_2026!Kot.
• 🔄 Disable WPS (This is a vulnerable protocol that can be hacked in a few hours).
• 📡 Hide SSID (network name) is not a panacea, but it will reduce the number of accidental connections.
• 🔒 Enable MAC filtering (allow only known devices to connect).

Additional measures:

• 🛡️ Install VPN on a router (For example, OpenVPN or WireGuard). This will encrypt all traffic.
• ⚡ Update your router firmware (outdated versions often contain critical vulnerabilities).
• 📱 Set up notifications about new devices (for example, through Fing or NetScan).

For maximum security, consider using firewall on the router. For example, in Keenetic there is a built-in IDS/IPS (intrusion detection system) that blocks suspicious activity.

If you suspect your router has already been compromised (for example, the password is incorrect, or the settings are resetting themselves), perform a hard reset:

1. Click the button Reset on the back panel of the router (hold for 10-15 seconds).
2. Reset your router from scratch (do not restore a backup!).
3. Change administrator password (don't leave the default one admin).

8. Common mistakes and how to avoid them

When checking Wi-Fi devices, users often encounter common issues. Here's how to solve them:

Problem 1: The application shows an incomplete list of devices.

• 🔌 Cause: The router is blocking ARP-scanning or devices are sleeping.
• 🔧 Solution: Use the router's web interface or wake up devices (for example, turn on a smart light bulb).

Problem 2: Unknown devices appear and disappear.

• 👻 Cause: These could be neighbors with the same network name or gadgets connected to your guest network.
• 🔍 Solution: Check your guest access settings and change your network name (SSID).

Problem 3: After changing the password, old devices still connect.

• 🔄 Cause: The router saves MAC-addresses in the white list or the function is used WPS.
• 🔧 Solution: Reset your router to factory settings and set it up again.

Problem 4: The application requests root rights.

• 📱 Cause: Some features (such as deep traffic analysis) require advanced permissions.
• 🔒 Solution: Use alternative applications (eg. Fing works without root).

If none of these methods help identify all devices, the problem may be with the router itself. Some models (especially budget ones) have a limit on the number of clients displayed in the web interface. In this case, the only solution is to replace the hardware.

⚠️ Attention: Router interfaces and app features may change depending on updates. If any section in the admin panel is missing, check the documentation for your model on the manufacturer's official website.

FAQ: Answers to frequently asked questions

Is it possible to find out which devices were connected to my Wi-Fi a week ago?

Most home routers don't store connection history for longer than 24 hours. Long-term monitoring requires specialized systems (for example, PRTG Network Monitor) or enterprise-class routers (for example, Ubiquiti or MikroTik), which keep logs.

Alternatively, you can set up Automatic export of device list through Fing or NetScan (for example, send a report by email once a day).

How do I block a device by MAC address if I have a router from my ISP?

Even if your router is provided by an ISP (e.g., Rostelecom or Beeline), you can usually still block devices by MAC address. Here’s how:

1. Log in to the router’s web interface (usually 192.168.0.1 or 192.168.1.1).
2. Look for sections like MAC Filtering, Access Control, or Parental Controls.
3. Add the suspicious device’s MAC address to the blacklist.
4. Save the settings and restart the router.

If these options are missing, your ISP may have restricted access. In this case, contact their support or request a router unlock.

Can my neighbor connect to my Wi-Fi even if I set a strong password?

Yes, there are several ways to bypass protection:

• 🔍 Password selection: If the password is weak (for example, 12345678), it can be hacked using brute force.
• 📡 WPS attack: A vulnerability in the WPS protocol allows you to connect in a few hours, even if WPS is disabled in the settings.
• 🕵️ PhishingA scammer can create a fake network with the same name and intercept your traffic.
• 🔌 Router vulnerabilities: Old firmware may contain vulnerabilities (for example, KRACK in the protocol WPA2).

To minimize risks:

• Use WPA3 instead of WPA2 (if the router supports it).
• Turn it off WPS And UPnP.
• Update your router firmware regularly.

How can I distinguish my device from someone else's in the list of connected devices?

Here are some ways to identify your gadgets:

• 📱 By name: Most devices are displayed with a model (eg. iPhone-12-Pro, Galaxy-S22).
• 🔢 By MAC address: The first 6 characters indicate the manufacturer (e.g. Apple, Samsung). The full list can be found on the website MAC Vendors.
• 📡 By IP address: Remember the range DHCP your router (for example, 192.168.1.100–192.168.1.200) - static IPs are usually allocated outside this range.
• ⚡ By activity: Disconnect all your devices from Wi-Fi and see which ones are still online.

If the device is unknown, but its MAC starts with B8:27:EB - This Raspberry Pi, 78:31:C1 — Apple, 00:1A:79 — Sony.
