Q: Where is the extension icon?
A: A recent Chrome update changed how extensions are displayed. You need to click on the puzzle icon to the right of the address bar and then pin Internet Connection Monitor

Q: What exactly can be monitored?
A: The extension monitors the Internet connection and reports 3 statuses:
  • Online: Wi-Fi/Ethernet connection is stable, Internet connected
  • Connection issues: Wi-Fi/Ethernet connection is stable, no Internet - most likely, provider issue
  • Offline: Wi-Fi/Ethernet is down, no Internet
Q: How does the extension test the connectivity?
A: The extension uses a combination of Chrome internal API and pinging Google servers via https (port 443). It does not expose any open ports or something else that could compromise user's security

Q: What is the testing interval?
A: Every 3 seconds

Q: Does this extension have access to my browsing history, etc?
A: It does NOT. Moreover, it does not require any special access at all (you can notice that some other extensions ask you to give them some permissions during the installation process)

Q: Can this extension measure Internet speed?
A: It cannot. Please, use Speedtest by Ookla

Q: Will it work if Chrome is closed?
A: Not, it will not. You need to have a Chrome window open to track your connection log. It's relatively easy to add Chrome to autostart on Windows, Mac or Linux
