Your internet is slow. A device you don’t recognise showed up in your router’s connected list. You’re wondering if someone has jumped on your WiFi without permission. The good news: checking takes less than five minutes, requires no technical knowledge, and your router’s admin panel shows you exactly who is connected right now. Here’s how to check, what you’re looking at, how to kick off any unauthorised devices, and how to lock down your network so it doesn’t happen again.

How to See Who’s Connected Right Now
Every router has an admin panel that shows connected devices. Accessing it takes 60 seconds on any phone or computer. My step-by-step below works for the most common home routers — BT Hub, Sky Router, Virgin Media Hub, and most third-party routers.
HOW TO ACCESS YOUR ROUTER ADMIN PANELCopy
Step 1: Find your router’s IP address
Windows: open Command Prompt → type: ipconfig → look for “Default Gateway”
Mac: System Settings → Network → your connection → Router IP
iPhone: Settings → WiFi → tap your network name → Router
Android: Settings → WiFi → tap network → Advanced → Gateway
Most common default: 192.168.1.1 or 192.168.0.1 or 10.0.0.1
Step 2: Open router admin panel
Open any browser → type the router IP into the address bar
You’ll see a login page. Default credentials (if you haven’t changed them):
BT Hub: admin / password on a label on the router
Sky Router: admin / sky (often printed on the router)
Virgin Media: admin / changeme (or label on the router)
Netgear: admin / password
TP-Link: admin / admin
Step 3: Find the connected devices list
Look for: “Connected Devices” / “DHCP List” / “Device List” / “Attached Devices”
Usually under: Home / Status / Basic / or a devices icon
You’ll see: device name, IP address, MAC address, connection type (WiFi/wired)
Faster alternative: WiFi analyser app
Android: “WiFi Analyzer” (free on Play Store) → see all connected devices
iPhone: “Fing” (free) → network scan → shows all devices with names

WiFi ⚠️
⚠️ “android_a3f92” — generic name, not recognised. Investigate this device.
📸 Example connected devices list from a router admin panel. Three devices are clearly identifiable (iPhone, laptop, TV). The fourth — “android_a3f92” — has a generic auto-generated name. This could be a neighbour using your WiFi, a guest who connected months ago and never disconnected, or a device with a privacy MAC address (a normal security feature on modern phones). The next step is identifying it before taking action.
How to Identify Unfamiliar Devices
Seeing an unfamiliar device name doesn’t necessarily mean you’ve been compromised. Modern phones use randomised MAC addresses as a privacy feature — meaning your own devices might show up with generic names. My method for identifying every device on the list before assuming the worst.
DEVICE IDENTIFICATION CHECKLISTCopy
Count your own devices first
Phones (everyone in household) · Laptops · Tablets · Smart TVs
Smart speakers (Alexa, Google Home) · Streaming sticks (Chromecast, FireStick)
Games consoles · Smart doorbells/cameras · Smart home devices
Printers · NAS drives · Work laptops
Most households have 10–20 devices — it adds up fast
Identify devices by MAC address manufacturer
First 6 characters of MAC address = manufacturer OUI code
Look up at: maclookup.app or macvendors.com
Example: A4:C3:F0 = Apple · F8:75:A4 = Samsung · DC:A6:32 = Raspberry Pi
MAC address randomisation (common false alarm)
Modern iPhones, Android phones generate random MAC per network by default
Your own phone may show as “android_xxxxx” or random characters
Check: disable Private Address in phone WiFi settings → see if it gets a recognisable name
Still can’t identify it? Try blocking it temporarily
Router admin → MAC filter → block the unknown device
Walk around your home — does anything stop working?
If nothing stops working in 5 minutes: likely someone else’s device
