Spectrum Scryer

See every Wi-Fi access point in your neighbourhood โ€” the hidden ones too โ€” laid out across the 2.4, 5 and 6 GHz bands, with a locator that walks you to any of them. Everything happens in your browser; nothing is uploaded anywhere.

Ask your device for the airwaves

Browsers are not allowed to scan Wi-Fi on their own, so we borrow your computer’s own scanner. Copy the one-line command below, run it, and paste what comes back โ€” the Scryer does the rest.

Open Command Prompt or PowerShell.

netsh wlan show networks mode=bssid

Windows only lists networks it can hear right now, so give it a few seconds after switching Wi-Fi on.

Other things on the air

Wi-Fi is not alone up there. These readings come straight from the browser โ€” no commands, no pasting.

Bluetooth & BLE 2.4 GHz

Headphones, watches, trackers, sensors and beacons share the 2.4 GHz band with Wi-Fi. Scanning asks for your permission every time.

    Honest small print

    Why can’t the page just scan by itself?

    No browser exposes a Wi-Fi scanning API โ€” that would let any website work out exactly where you live. Your operating system will happily tell you, though, which is why the Scryer asks you to paste its answer. The parsing, charting and locating all happen locally in your browser, and nothing ever leaves the page.

    How are hidden networks found?

    A “hidden” network only stops broadcasting its name. It still announces its MAC address (BSSID), channel and signal every few seconds, so every scanner sees it. The Scryer flags those nameless entries and shows their vendor and channel instead. Hiding a network is not a security feature โ€” treat these like any other neighbour.

    What about microwaves, drones and other 2.4/5/6 GHz noise?

    Anything that is not Wi-Fi or Bluetooth needs real radio hardware โ€” a spectrum analyser or an SDR dongle. What a laptop can tell you is where the interference bites: an overcrowded channel in the map above, or a 2.4 GHz link that mysteriously stalls around dinner time, is usually a neighbour, a microwave or a cordless doorbell.

    Is any of this legal and polite?

    Listening to the beacons that networks broadcast is normal and passive โ€” your phone does it constantly. Connecting to a network you have no permission to use is not. Scry responsibly.
