Upon Launching Brave: NO INTERNET

Description of the issue:I have 4 tabs saved to open upon launching the Brave browser. Each day when I log into my system I launch these same sites as they are most commonly used. Upon opening the browser, there’s a banner across the top that says “NO INTERNET” and that goes away each time in 2-3 seconds, so my assumption is it’s just launching but I’m here to ask why it’s showing that (has my connection been re-routed? intercepted? is it the system network that drops or just this application (everything else seems to work without interruption)? Assuming, because of this no network connection, a few of the tabs actually display an error saying that the page didn’t load and needs to be refreshed. So apparently the browser was interrupted while trying to load each site under a different tab. Once I hit the refresh button they come up instantly.

This has been bothering me and I’d like an explination if I can find one. What’s interrupting the launch? What is causing the sites under some of the tabs to fail?

Here are the sites:

Internal Network IP #1
Internal Network IP #2

**Expected result: I would expect the browser to launch without immedately showing “NO NETWORK.” Worst fear: upon launching the browser’s establishing traffic somewhere other than where I expect it to go and it’s creating a tunnel.

Because it is very simple, and thereby the browser starts up - unburdened. You know the browser is running, and you have an Internet/www connection.

I am not sure I understand what you mean by " unburdened." Because it’s like for that first 1-2 seconds it’s got internet, loading, then pops up no connection, then I refresh and it’s working again. If this is intentional it makes the user experience jump to conclusions that something is broken.

Brave Browser is a Chromium engine’d web browser. Same for Google Chrome and Microsoft Edge.

Multi-Process Model Background

To understand Chromium’s memory usage, let’s understand the multi-process model. Unlike other browsers, Chromium is divided into multiple processes.

When Chromium starts up, it will initially have two processes.

One process is the browser process which controls the main browser functionality, and the other is the initial renderer process , which runs the Blink rendering engine and JavaScript (V8).

Each time you open a new tab in Chromium, you’ll likely get a new renderer process.

With typical browsing, it is common to see 5-7 chrome.exe processes active.

Further, if you utilize plugins, apps, or extensions, they may also execute within independent processes.

All of Chromium’s processes, whether it is a browser process, a renderer process, or a plugin process, will show under the Task Manager as “chrome.exe”.

Monitoring Brave Browser and Mac OS at the same time:

Brave Browser Task Manager window on the left.

MacOS Activity Monitor on the right. Compare the Process ID (“PID”) numbers. You’ll get the idea.

All of the following are diagnostic tools:

Opening the Developer Tools window

  • MacOS users, key combination: Command + Option + “I” (no quotes)
  • Windows OS users: key combination: Control + Shift + “I” (no quotes)

On the first occasion of using Developer Tools, the Developer Tools “window” is usually a part of (contained within) its associated Brave Browser window . . . but you can make the Developer Tools window, a standalone window (though keeping its association with the Brave Browser window). I recommend that you do so:

In the upper right-hand corner of the Developer Tools window, there is an “Organizer” 3-vertical-dots button - click on that. The result should be a pop-up:

Notice the tiny blue icon that is first (left to right) among 4. Click on that icon. The Developer Tools window will become a standalone window.

By monitoring the Developer Tools window > Network tab, you can observe the “behind the scenes” networking activity between the Internet browser and the website.
