Find out where your connection breaks
WiFi Wise checks your connection layer by layer - your link, your router, the internet, DNS and the web - then pinpoints the first thing that fails and gives you a status code you can look up or share.
What it checks
Every layer of your connection, in seconds.
Network link
Confirms an active Wi‑Fi, ethernet or cellular link and shows your address.
Your router
Checks whether your gateway is reachable, and how fast it responds.
Internet
Tests reachability beyond your router to tell a router fault from an ISP outage.
DNS
Verifies that names like example.com actually resolve to addresses.
Captive portals
Detects hotel, airport and cafe login pages intercepting your traffic.
Connection quality
Measures packet loss, latency and jitter so you can spot a degraded link.
One tap, one clear answer
Instead of a vague “No Internet”, WiFi Wise runs through the connection in order and
stops at the first thing that's wrong. You get a plain‑English verdict and a
short status code like NET‑230 - which you can look up here or share with whoever
is helping you fix it.
Private by design
No accounts, no servers, no tracking. Diagnostics run entirely on your iPhone - the only traffic is the diagnostic probes themselves.
