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: Internet connected
  • Connection issues: ICM uses different mechanics to determine whether internet connection is up and running. If Chrome itself cannot properly determine whether Internet connection is down while you're connected to Wi-Fi/Ethernet - this status will popup. It tells you that most likely your Wi-Fi/Ethernet cable is connected, but there is no Internet connection after it. Most likely, it is a provider issue
  • Offline: Internet disconnected. Wi-Fi/Ethernet may work or not, but Internet itself is unavailable
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: How frequently to ping Google servers to determine the status of Internet connection. The option is configurable: check very 1, 2, 3 or 5 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 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

Q: Can you use it on Microsoft EDGE?
A: Yes, you can Q: Is there a Firefox extension? A: Currently, only Google Chrome and Microsoft Edge are supported Icons by
