WiFi Analyser: WLAN Analyzer

Scan your Wi-Fi in ten seconds and see every device on it. Then a graded check-up tells you why it's slow — and whether the problem is your Wi-Fi or your provider.

Find every device on your Wi-Fi, see which ones do not belong there, and find out why your connection is slow.

WiFi Analyser measures your network instead of guessing about it. Every number you see is one it took on your own connection.

WHO IS ON YOUR NETWORK • Full scan of your Wi-Fi in about ten seconds • Devices identified by their Bonjour name, hostname or the services they run — and the app tells you which of those it used • Sorted by type: phones, computers, TVs, printers, speakers, consoles, storage and smart home • New devices flagged the moment they appear • Rename anything, and mark the ones that are yours • Open a device's own web page when it has one

WHO'S ON YOUR WI-FI • Devices split into yours, not recognised yet, and worth a look • Camera-type devices called out separately • Everything you mark as yours drops off the list, so it stays short

WI-FI CHECK-UP, GRADED A TO F Six real measurements, about a minute: • Delay to your router and delay to the internet, measured separately, so you know whether the problem is your Wi-Fi or your provider • Lost data and steadiness, the two things that break video calls • Website lookup speed, side by side with Cloudflare and Google • Real-world speed Then it tells you what the numbers mean in plain language: distance from the router, a crowded channel, or your provider's side.

WHAT THIS WI-FI CAN HANDLE Video calls, 4K streaming, online gaming, browsing — each answered yes, borderline or not really, from the numbers just measured.

ROOM BY ROOM • Walk around and measure each spot • Every spot is measured against the same target, so the numbers compare • Ranked weakest first, so you can see where the router stops reaching

IS THIS NETWORK SAFE? Three checks before you sign in to anything on public Wi-Fi: • Whether the network is encrypted or open • Whether anything is intercepting web requests • Whether it hijacks address lookups instead of letting them fail

HOW FAST ARE YOUR APPS • Times the apps you actually use: YouTube, Instagram, TikTok, WhatsApp, Netflix, Spotify, Zoom • Instant, fine or slow for each one • Tells you whether it's one app or your whole connection

SPEED TEST • Download, upload and ping • Live graph, so you can see the dips • Full history, filtered by network • Share the result

ADVANCED PING Ping any address you type in: round-trip time on a live graph, plus fastest, average, slowest, jitter and packet loss.
