## Overview

**Diagnostics** does three separate jobs. The big card at the top runs a
diagnostic sweep of the router and produces a report file you can download or
hand to support. A timeline shows which of the nine checks it is on. Below
that, **Error Reports** switches the panel's anonymous crash reporting on and
off for this browser. **Reset Configuration** wipes the router's setup and
sends you back through the Easy Config wizard.

The reset is the destructive one. Everything currently configured on the router
goes, and there is no undo.

## Before you start

- The session needs valid credentials, because the **Start** button stays disabled
  without them.
- A reset takes the router back to an unconfigured state, so plan for the
  downtime.

## Steps

### Running a report

1. Press **Start**. The timeline advances through the checks.
2. When it finishes, a file tile appears with the report name and the time it
   was generated.
3. Press **Download** to save it.
4. Press **Run again** to produce a fresh report.
5. Press **Talk to support** to jump to the Help tab with the report in hand.

### Error reporting

1. Find the **Error Reports** card.
2. Use the **Send error reports** switch to turn reporting on or off. The
   setting is per browser.

### Resetting the router

1. Press **Reset and Reconfigure**.
2. Read the confirmation dialog, then confirm.
3. The Easy Config wizard opens from the beginning.

## Reference

### Diagnostic checks

| Check | What it covers |
| ----- | -------------- |
| System info | Resources and packages |
| Installation check | Panel install status |
| Interfaces | Links and addresses |
| WiFi | Wireless interfaces |
| Routing | Tables and rules |
| DNS | Config and resolution |
| VPN | Clients and servers |
| Connectivity tests | WAN and VPN pings |
| Logs | Recent errors |

### What an error report contains

Reports carry the error, a stack trace, the app version, and your browser and
OS name. They never include the router address, credentials, configuration,
request or response bodies, console output, or any user identity, and every
IPv4 and IPv6 address is replaced with `[ip]` before the report leaves the
browser. The report is sent by your browser, not by the router, and only from
production builds.

## Troubleshooting

**The Start button is disabled.** The session has no credentials for this
router, or a run is already in progress. Reconnect from the Routers list.

**"Failed to download report".** The report was generated but could not be
fetched. Run it again.

**The reset dialog appeared by accident.** Press cancel. Nothing happens until
you confirm.
