## What is Net Trouble Checker?

When internet is slow, a site will not open, or a local device is missing, use symptom-based diagnostics and focused tools to organize likely causes and next steps.

Key features:

- Simple symptom-based diagnosis
- Download speed (up to about 8 MB or five seconds), internet access, DNS, response time, loss, and jitter checks
- Estimated-router and LAN-device checks while connected to Wi-Fi
- Focused tools for speed, DNS, LAN devices, Ping, and internet access
- Clear results with likely causes and what to try next
- On-device history and text sharing that redacts IP addresses and other network identifiers
- Shared reports include the app version at report creation

Privacy and storage:

- No account required
- History saving is optional; turning it off does not automatically delete existing records
- Shared reports redact IP addresses, MAC addresses, the estimated router, hostnames/DNS names, and LAN device names
- Diagnosis results and history are not sent to the developer's server
- Diagnosis results and history are not included in ad requests

Limitations:

Because of iOS restrictions, LAN-device discovery may be incomplete. The Slow Internet diagnosis and Speed tool download up to about 8 MB or for up to five seconds from nwchk.elevenback.co.jp, ElevenBack's speed-test server, and calculate download Mbps on device. The speed needed depends on the activity, and results vary by time of day and network conditions.
