Local WiFi Check: see every device on your Wi-Fi network
Free, private Wi-Fi scanner: see which devices are connected to your home network, their names and makers, your public IP and router address, and open your router settings. Runs in your browser with a small helper on your computer; Android and iPhone apps are in development.
Features
- Scan your Wi-Fi and see every device that answers, with a clear count.
- Real device names from your router, Bonjour, UPnP and Windows names, plus the maker of each network chip.
- Your public IP, local IP and router address in one place.
- One tap to open your router’s settings page.
- Internet speed test (ping, jitter, download, upload) with a plain-language “what can you do with this speed” summary.
- Name your devices; see what’s new or missing since the last scan.
- Private by design: no account, no cloud, results stay on your device.
How to see the devices connected to your Wi-Fi
- Connect your phone or computer to the Wi-Fi network you want to check.
- Open Local WiFi Check (on a computer, start the scanner helper with “npm run agent” and open http://localhost:47811).
- Tap Scan and wait about 30 seconds.
- Read the list: each device shows its name, type or maker, and local IP address.
- Tap a device to give it your own name, or tap “Open router settings” to manage your router.
Questions and answers
How do I see which devices are connected to my Wi-Fi?
Open Local WiFi Check on a phone or computer joined to your Wi-Fi and tap Scan. In about 30 seconds it lists the devices that answer, with their names, makers and local IP addresses.
Only scan networks you own or are allowed to inspect.
Why doesn’t the count match what I expect?
A scan can only list devices that answer it. Sleeping phones, firewalls, guest networks and mesh systems can hide devices.
Results are labelled “Scan detected” for that reason: the real number may be higher.
Does a device count mean a person?
No. One person may have several devices, and TVs, plugs and printers have no person behind them. The app never guesses who owns a device.
Why is a device called “Unknown device”?
It answered, but didn’t tell the network its name. Phones with a private (randomised) Wi-Fi address often do this.
Tap it and give it a name you recognise. The name is remembered.
How do I test my internet speed?
Open the Speed test section and tap GO. In about 20 seconds it measures ping, download and upload against Cloudflare’s nearest server.
It then explains what your speed is good for: how many 4K streams, video calls, gaming and how long a 1 GB download takes. It uses up to about 180 MB of data, less on a steady connection.
Can I see the MAC address of each device?
Yes, in the web app on a computer: open any device to see its MAC (hardware) address, the maker of its network chip, and a copy button. Phones aren’t allowed to read other devices’ MAC addresses.
Phones and tablets often use a private (randomised) Wi-Fi address for privacy; the app marks these, because they aren’t the device’s built-in address.
Can it show how many people are at home?
Not from a device scan: one person may own five devices and a TV owns none. The People at home section shows an estimate from a RuView Wi-Fi sensing server you run yourself, using small ESP32 sensors that notice how bodies disturb the Wi-Fi signal.
It is an estimate with a confidence level, not a head count, and it never identifies who is there. Without a sensing server the section explains what you need.
Can I block a device or limit its speed?
Yes, in Router controls, if your router is supported (Linksys Smart Wi-Fi and Velop, and FRITZ!Box, today). Log in with the router’s own admin login and you can block or unblock any device except the router and the device you’re using. Each block asks you to confirm. On a FRITZ!Box, blocking turns off internet access while the device stays on your home network.
Speed limits per device are only possible on routers that support them; many routers (including Linksys Velop models and FRITZ!Box) can’t, and the app says so. Instead, you can pause a device or a group of devices at set times.
What is my public IP?
It’s the address the internet sees for your whole network, given by your internet provider. Every device at home shares it.
Local addresses (like 192.168.1.20) are only used inside your network.
How do I open my router’s settings?
Tap “Open router settings”. Your browser opens the router’s own page, usually at an address like 192.168.1.1.
You’ll need the router’s admin password, which is often printed on a sticker on the router.
Why is my Wi-Fi name hidden?
Phones and Windows only share the Wi-Fi name with apps that have location access. On Windows, Local WiFi Check shows the name of the saved network instead; on a phone, tap “Show Wi-Fi name” and allow location.
Your location is never stored or sent.
Only this device was found
Make sure you’re on your main Wi-Fi, not a guest network. Guest networks and “client isolation” (common in hotels and offices) hide devices from each other on purpose.
