If your internet feels slower than it should, or you're just security-curious, here's how to enumerate every device currently connected to your Wi-Fi — and what to do about anything you don't recognize.

Method 1: Router's connected device list

Easiest and most authoritative source. Log into your router admin page, find Attached Devices, DHCP Clients, or Connected Devices. You'll see hostname, MAC address, IP, and connection time for everyone currently on.

Method 2: Network scanner apps

Install Fing (free, iOS and Android) or run Angry IP Scanner on a laptop. Scans your subnet and lists every responsive device with manufacturer info pulled from the MAC address. Often more readable than your router's list.

Method 3: nmap (advanced)

From any computer on the same network: nmap -sn 192.168.1.0/24 (replace with your subnet). Lists every live host. Add -O to fingerprint operating systems. Useful for power users.

Identifying what's what

• Recognize phones, laptops, tablets, smart TVs, game consoles by hostname
• IoT devices often have generic names (ESP_xxx, Tuya-xxx) — check by MAC manufacturer prefix
• Anything you can't account for after listing every device in your house is a candidate intruder

If you find an intruder

1. Change your Wi-Fi password. Forces every device to reconnect. Yours will, theirs won't.
2. Block by MAC in your router admin (most routers support a deny list).
3. Audit your security: WPA3 if available, no WPS, no default admin password. Run our Wi-Fi hardening checklist.
4. If it persists, the attacker may have your password — change it again and check whether it was leaked elsewhere.
