How to See Every Device Connected to Your WiFi Network: Router Admin, Apps, and ARP Scanning Methods Compared

Most home networks have far more connected devices than their owners realize. Between phones, laptops, smart TVs, streaming sticks, smart speakers, thermostats, and security cameras, the average home now has 25 or more active WiFi clients at any given time. Knowing how to audit that list — and identify anything that shouldn’t be there — is a basic home network skill. Here are the four methods, from quickest to most thorough.

Method 1: Your Router’s Admin Panel (Most Reliable)

The router admin page is the authoritative source for connected devices because every connection must pass through the router. The list is maintained in real time by the router’s DHCP server, which assigns and tracks IP addresses for every client.

To access it, open a browser on any device connected to your network and navigate to your router’s local IP address. The most common addresses are 192.168.1.1 or 192.168.0.1. If neither works, check your default gateway: on Windows, open Command Prompt and run ipconfig — the “Default Gateway” line is your router’s address. On macOS, go to System Settings → Network → your active connection → Details → TCP/IP tab.

Log in with your admin credentials (usually printed on a label on the router itself). Then look for these sections depending on your brand:

• TP-Link Archer: Advanced → Network → DHCP Server → Address Reservation, or Advanced → Status → Client List
• ASUS (Asuswrt): Network Map → click the Clients icon in the center — use the Online, Wired, and Wireless tabs to filter
• Netgear Nighthawk: Connected Devices (in the main nav) or Advanced → Administration → Attached Devices
• eero: The admin panel at gateway.eero.com shows connected devices, though the app is easier (see Method 2)
• Linksys: Status → Local Network → DHCP Clients Table

The device list will show each client’s IP address, MAC address, and hostname (device name). Hostnames are set by the device itself and are not always descriptive — you may see entries like “android-a3f2b1c9d” or “ESP_3A2F14” alongside more readable names like “John’s iPhone.”

If you find a device you don’t recognize, don’t immediately assume it’s an intruder. Cross-reference the MAC address against a MAC OUI lookup tool (search “MAC address lookup”) — the first three octets identify the manufacturer, which often reveals whether the unknown entry is your smart TV, your neighbor’s misconnected phone, or something else. For steps on removing unauthorized devices, see our guide on upgrading your router security to WPA3.

Method 2: Your Router’s Companion App (Quickest)

Most modern routers have a smartphone app that surfaces connected devices in a cleaner interface than the web admin page. These apps often add device categorization, usage statistics, and the ability to pause or block individual devices — features the web UI buries or omits entirely.

• TP-Link Tether: Open the app, tap your router, then tap Clients or Online Clients for a live list with icons for each device type
• ASUS Router app: Tap the Clients icon on the home screen; devices are grouped by wired and wireless, with signal strength and real-time traffic for each
• Netgear Nighthawk app: Tap Connected Devices on the dashboard; you can set device names and pause internet access per device
• eero app: Tap Network → Devices to see every connected and recently connected device, sorted by active status
• Google Home app: Select your WiFi → Devices to see all clients on a Google Nest WiFi or Google Wifi network

Apps are the fastest option for a quick check, but they only see devices that are currently connected or have recently been connected. A device that was connected six hours ago and has since gone offline may show in the app as “inactive” or may have already dropped off the list entirely, depending on the app’s history window.

Method 3: ARP Scan From the Command Line

The ARP (Address Resolution Protocol) table maintained by your computer maps IP addresses to MAC addresses for every device it has recently communicated with on the local network. Running arp -a in a terminal gives you a quick snapshot — no software installation required.

Windows

Open Command Prompt (press Win + R, type cmd, press Enter) and run:

arp -a

The output lists every IP address your computer has recently communicated with on the local network. Entries in the dynamic column are active neighbors; static entries are manually configured or cached from a previous session.

macOS and Linux

Open Terminal and run:

arp -a

For a more thorough active scan on Linux (requires the arp-scan package):

sudo arp-scan --localnet

This sends ARP requests to every address in your subnet and reports all responding devices — including some that may not appear in the passive ARP table because your computer hasn’t communicated with them directly.

Using nmap for a Full Subnet Scan

nmap is the most thorough command-line option. Install it from nmap.org, then run:

nmap -sn 192.168.1.0/24

Replace 192.168.1.0/24 with your actual subnet if different. The -sn flag performs a ping scan without port scanning, so it’s quick and non-intrusive. nmap reports the IP, MAC address, and manufacturer for each responding host. This is the most complete picture available from a client device.

Method 4: Third-Party Network Scanner Apps

If you want a graphical interface without touching the router admin page, several third-party apps do active network scanning with better device identification than the ARP table alone.

• Fing (iOS, Android, Windows, macOS): The most popular option. Performs an active scan using ICMP ping and ARP, identifies device manufacturers, attempts to detect device type (phone, laptop, IoT sensor), and flags new devices that appear since your last scan. The free tier covers basic device discovery; Fing Premium adds continuous monitoring and intruder alerts.
• NirSoft Wireless Network Watcher (Windows, free): Lightweight portable app that scans your subnet and displays every responding device with IP, MAC, manufacturer, and computer name. No installation required.
• LanScan (macOS, free): Simple subnet scanner that shows IP, MAC, hostname, and manufacturer. Useful for a quick check without opening Terminal.

Third-party apps are convenient, but they require your device to be on the same network as the devices you’re scanning. They also cannot see devices that are connected via a separate VLAN — for example, if you’ve isolated your IoT devices on a separate network using a VLAN for smart home devices, those clients won’t appear in a scan from your primary network.

Why Some Devices May Not Appear

Two features in modern devices can make them harder to identify or track:

• MAC address randomization: iOS 14 and later, Android 10 and later, and Windows 10 build 1903 and later all randomize the MAC address used when connecting to WiFi networks by default. This means a single device may appear under different MAC addresses on different connections, making it harder to track across sessions. On iOS, you can see the assigned private address in Settings → WiFi → your network → Private WiFi Address.
• Devices that don’t respond to ping: Some devices have firewalls that drop ICMP echo requests, making them invisible to ping-based scanners like nmap’s -sn flag. ARP-based scans (arp-scan, Fing) are more reliable because ARP responses are required for basic network functionality and are harder for device firewalls to suppress.

For the most complete picture, combine Method 1 (router admin DHCP table) with a Fing or arp-scan sweep. The router sees every connection at the DHCP layer; the active scanner catches devices that may have static IPs and don’t appear in the DHCP table.

What to Do With Unknown Devices

If you find a device you can’t identify after checking the MAC manufacturer and reviewing your own devices, the safest response is to change your WiFi password immediately. All clients will be disconnected and must re-authenticate with the new password — unauthorized devices won’t have it. Follow up by enabling WPA3 if your router supports it (see our guide on enabling WPA3), and consider setting up a guest network to isolate future visitors from your primary devices. If your router supports access control lists, you can also add your known devices’ MAC addresses to an allowlist — though MAC filtering alone is not a strong security control since MAC addresses can be spoofed. The password change and WPA3 upgrade are what matter.

Ongoing Monitoring

A one-time scan is a starting point, not a security posture. For ongoing visibility, check your router’s device list whenever you notice unexplained slowdowns or if you’ve recently had guests on your network. Some routers — and the Fing app — can send push notifications when a new device joins, which is the most proactive option. Our guide on monitoring your WiFi signal over time covers the broader set of tools for keeping an eye on network health beyond just the device list. Run a speed test if a new device has appeared alongside a noticeable drop in performance — unauthorized clients can consume significant bandwidth.
