Download NetavoCheck

Running NetavoCheck

Windows

NetavoCheck is not yet code-signed, so the first time it runs Windows shows “Windows protected your PC”. Select More info, then Run anyway. Double-click the downloaded file and a window opens that runs the checks, which take a minute or two. It asks before uploading the results, then opens the report in your browser with its reference.

macOS

Open the downloaded NetavoCheck-macos.dmg, then double-click Netavo Check. The first time, macOS asks whether to open an app downloaded from the internet: choose Open. A Terminal window opens that runs the checks, asks before uploading the results and then opens the report in your browser. You can also drag Netavo Check to Applications to keep it.

Command-line options

NetavoCheck also runs from a command prompt or Terminal:

• --sites a.com,b.com tests the websites that are not working, as well as the usual list.
• --json prints the report as JSON instead of a summary.
• --no-upload runs the checks without offering to share them.

Compare a download’s SHA-256 with the value above to confirm it arrived intact: certutil -hashfile NetavoCheck-windows-x64.exe SHA256 on Windows, or shasum -a 256 NetavoCheck-macos.dmg on a Mac.

What It Collects

The device’s network adapters and their addresses, gateways and DNS servers; the Wi-Fi standard, band, channel and signal (not the network name); proxy settings and hosts-file entries; and the results of its DNS lookups, pings, packet-size tests and traceroutes. Nothing leaves the device until you agree to share it. A shared report can be opened by anyone with its reference for 7 days.
