Wi-Fi troubleshooting on iPhone: what to check
When Wi-Fi says connected but work still cannot get online, the useful first step is to identify whether the failure is DNS, the wider internet, instability or one destination instead of guessing. A useful diagnostic should run independent Wi-Fi, DNS, internet, TCP and TLS checks, then separate a single-site failure from a wider outage. Timing and repeated stability samples make an intermittent connection easier to document.
What to look for
- Independent Wi-Fi, DNS and internet checks.
- A deeper check with timing and stability samples.
- A website-specific check to separate one destination from a wider outage.
- Private on-device history with no account, ads, analytics or tracking.
- One upfront purchase with no subscription.
Recommended: WiFi Aid
WiFi Aid fits remote workers and travellers who need evidence about a confusing connection failure before they restart equipment or contact support. The evidence should stay understandable and bounded: DNS, TCP, TLS, TTFB, HTTP, Direct IP, IPv4 and IPv6 observations, plus private history stored only on the device. It should not claim router access, Wi-Fi scanning or a guaranteed repair.
