How to Check Who Is Connected to Your WiFi Network (2026 Guide)

by Sarah Chen Updated Apr 12, 2026

Check Who Is On My WiFi

Is your WiFi slower than it should be? Suspect someone is using your network without permission? Checking who is connected to your WiFi is simple and takes less than a minute. Every connected device—authorized or not—appears in your router's client list with identifying information you can use to spot intruders.

This guide shows you how to see every device on your WiFi using your router's admin panel, command-line tools, and mobile apps, plus what to do when you find unauthorized users.

Key Takeaways
  • Your router's admin panel shows every connected device with its name, IP, and MAC address.
  • You can also scan your network from the command line or a mobile app.
  • Compare the number of connected devices to the devices you own—extras may be intruders.
  • Unknown devices often display as manufacturer names (e.g., "Espressif" = smart plug, "Murata" = Nintendo).
  • If you find unauthorized devices, change your WiFi password immediately.

Method 1: Check via Router Admin Panel (Most Reliable)

Your router maintains a list of every device currently connected or recently connected to your network.

  1. Open a browser and go to your router's IP address (usually 192.168.1.1 or 192.168.0.1).
  2. Log in with the admin credentials.
  3. Look for a section called Connected Devices, Attached Devices, Client List, DHCP Client Table, or Device List.
Router BrandPath to Connected Devices
NetgearAttached Devices (main page)
TP-LinkAdvanced → Network → DHCP Client List
ASUSNetwork Map (main page, click client icon)
LinksysStatus → Local Network → DHCP Client Table
D-LinkStatus → Client Sessions
XfinityConnected Devices (main page) or xFi app
Google/Nest WiFiGoogle Home app → WiFi → Devices

Each device entry typically shows:

  • Device name (sometimes "Unknown" for IoT devices)
  • IP address (e.g., 192.168.1.105)
  • MAC address (unique hardware identifier, e.g., 00:1A:2B:3C:4D:5E)
  • Connection type (WiFi 2.4 GHz, WiFi 5 GHz, or Ethernet)

Method 2: Scan from the Command Line

You can discover all devices on your network using built-in command-line tools.

Windows

arp -a

This shows all devices the router has communicated with recently. Each entry shows an IP address and MAC address.

For a more detailed scan, use PowerShell:

Get-NetNeighbor -AddressFamily IPv4 | Where-Object { $_.State -ne "Unreachable" } | Format-Table IPAddress, LinkLayerAddress, State

Mac / Linux

arp -a

For a more thorough scan (requires nmap):

# Install nmap first: brew install nmap (Mac) or sudo apt install nmap (Linux)
nmap -sn 192.168.1.0/24

Method 3: Use a Mobile App

Several free apps scan your network and provide a user-friendly device list with manufacturer identification:

  • Fing (iOS and Android) — Most popular network scanner. Identifies devices by manufacturer and type.
  • WiFi Analyzer (Android) — Shows connected devices and WiFi channel information.
  • LanScan (Mac) — Scans local network and identifies devices.
  • Router manufacturer apps (Nighthawk, Tether, ASUS Router) — Show connected devices natively.

How to Identify Unknown Devices

Found a device you do not recognize? Here is how to identify it:

  1. Check the device name: Names like "iPhone-Sarah" or "DESKTOP-ABC123" are obvious. Names like "ESP-12F" or "Tuya" are IoT devices (smart plugs, bulbs, cameras).
  2. Look up the MAC address: The first 6 characters of a MAC address identify the manufacturer. Search the MAC at macvendors.com to identify the device maker.
  3. Count your devices: Make a mental inventory: phones, laptops, tablets, smart TVs, gaming consoles, smart speakers, smart home devices, printers. If the count matches, you are fine.
  4. Disconnect devices one by one: Turn off devices you own and watch the list. The remaining device is the mystery one.
MAC Prefix / ManufacturerUsually Is
Apple, Inc.iPhone, iPad, Mac, Apple TV, HomePod
Samsung ElectronicsGalaxy phone/tablet, Samsung TV
Espressif Inc.Smart plug, IoT device (ESP32/ESP8266 chip)
Amazon TechnologiesAlexa, Fire TV, Ring doorbell
Google, Inc.Pixel phone, Chromecast, Nest device
Murata ManufacturingNintendo Switch (WiFi chip)
Intel CorporateWindows laptop/desktop
Tuya SmartGeneric smart home device

What to Do If You Find Unauthorized Devices

  1. Change your WiFi password immediately. This is the most effective step.
  2. Block the device using MAC address filtering for an extra layer of protection.
  3. Enable WPA3 or WPA2-AES encryption if not already active.
  4. Disable WPS (WiFi Protected Setup) as it has known vulnerabilities.
  5. Set up a guest network for visitors so your main password stays private.
  6. Check regularly by bookmarking the router's connected devices page.
Security Audit Checklist:
  • Strong WiFi password (12+ characters, WPA3/WPA2)
  • Changed default router admin password
  • WPS disabled
  • Router firmware updated
  • Guest network enabled for visitors
  • Regular connected device checks
Pro Tip: Set a monthly reminder to check your connected devices list. It takes 30 seconds and is one of the simplest ways to detect unauthorized access early. Many router apps (Nighthawk, ASUS Router, xFi) can send push notifications when a new device connects.

Frequently Asked Questions

Can I see what websites people are visiting on my WiFi?

Your router may log domain names (the websites visited), but the actual content of HTTPS-encrypted websites is not visible. Most routers do not log browsing by default. Some advanced routers (like ASUS with AiProtection) provide basic traffic analytics. However, monitoring others' browsing raises privacy and legal concerns.

Why does my connected device list show more devices than I own?

Count all your devices: phones, tablets, laptops, smart TVs, gaming consoles, smart speakers (Alexa, Google Home), smart plugs, smart bulbs, robot vacuums, printers, security cameras, and doorbells. Modern homes easily have 15–30 connected devices. The "extra" devices are usually forgotten IoT gadgets.

Can someone connect to my WiFi without the password?

If WPS is enabled, a vulnerability in the WPS PIN method can allow unauthorized access. Disable WPS in your router settings. Otherwise, with WPA2/WPA3 and a strong password, unauthorized access without the password is extremely difficult.

Does my ISP know who is on my WiFi?

Your ISP can see your public IP's traffic volume but cannot see individual devices on your local network. Only you (through the router admin panel) can see the list of connected devices.

How many devices can connect to WiFi at once?

Most consumer routers support 32–64 simultaneous connections. WiFi 6 routers handle more devices efficiently using OFDMA technology. Enterprise access points can support 100+ devices. If you are hitting the limit, consider upgrading your router or offloading devices to Ethernet.

Can I get notifications when a new device connects?

Yes, if your router supports it. ASUS routers (via the app), Netgear Nighthawk, Google/Nest WiFi, and some TP-Link routers can send push notifications for new device connections. Third-party apps like Fing also offer this feature.
