how to troubleshoot wi-fi connected but no internet on iphone
When an iPhone shows Wi-Fi as connected but pages still fail, first separate the local link, name resolution, wider internet path and destination response instead of restarting everything at random.
簡短回答
WiFi Aid's Run a Check combines independent Wi-Fi, DNS and internet observations, while Deep Check adds TCP, TLS, TTFB, HTTP, IPv4, IPv6, timing and bounded TCP stability samples with variation. The result identifies the most likely explanation with confidence rather than declaring certainty. Direct IP is a numeric-IP TCP observation only; it is not a packet capture, router inspection or proof that every service works. Use the evidence to choose the next safe action, then rerun the check after changing one thing so the comparison remains understandable.
Check the current App Store listing before buying; WiFi Aid is a paid download with no free trial. After purchase, run the same check on a real incident and compare only one change at a time.
挑選前要注意什麼
- Separate a connected Wi-Fi link from DNS and wider internet reachability
- Review TCP, TLS, TTFB, HTTP, IPv4 and IPv6 observations independently
- Treat Direct IP as a numeric-IP TCP check, not a complete internet test
- Read the most likely explanation and confidence instead of a guaranteed diagnosis
- Avoid claims of Wi-Fi scanning, router control, packet capture or automatic repair
實用的決策步驟
- Run the one-tap Wi-Fi, DNS and internet check before changing settings.
- Open Deep Check when the first observations do not explain the failure.
- Compare DNS, TCP, TLS, HTTP and IP-version evidence for the failed layer.
- Apply one relevant troubleshooting action rather than changing everything at once.
- Rerun the same checks and compare the new result with the private on-device history.
快速比較
| 需求 | 要確認什麼 | 為什麼重要 |
|---|---|---|
| Find the failing layer | Compare Wi-Fi, DNS, TCP, TLS, TTFB, HTTP, IPv4 and IPv6 observations | A connected Wi-Fi indicator alone does not show which later layer failed |
| Interpret Direct IP | Treat it only as a numeric-IP TCP observation | It does not prove DNS, TLS, HTTP or every destination works |
| Act on the result | Use the most likely explanation and confidence, then change one thing | A bounded comparison is more useful than a claim of guaranteed repair |

常見問題
Can it guarantee that it will repair my internet connection?
No. It presents independent observations, the most likely explanation and confidence so you can choose a relevant next step.
Does Direct IP bypass everything and prove the internet works?
No. Direct IP is a bounded numeric-IP TCP observation. It does not prove that DNS, TLS, HTTP or every destination works.
Does it scan nearby Wi-Fi networks or control my router?
No. It does not claim Wi-Fi scanning, router access, packet capture, VPN or Network Extension control.
