This only happens on my home machine which runs Windows 10 Pro, not on my work machine which also runs Windows 10 (I cannot remember which edition). I did not used to have this problem, but it started up several version of Chromium ago. I keep my browsers updated in hopes of this problem being fixed.

Can you please attach a net-internals log showing the issue? Instructions are at https://sites.google.com/a/chromium.org/dev/for-testers/providing-network-details.

I've actually been waiting for the problem to happen again so I could send off the information, but I since disconnected and reconnected my modem, and I haven't had the issue since. As soon as it does happen though, I will provide the log file.

It happened again. Here's the file. Please let me know if I didn't do this correctly or need to submit/resubmit anything.

Thank you!

Is this machine connected over wifi or ethernet? It looks like we keep triggering a NETWORK_CHANGED event.

It has a physical line to the cable modem, though I do have a wireless card available. 

Pulling out the cable and reconnecting it has been working so far though it's less than ideal.

Looks like every 3 seconds Chrome detects a network change event.
When you encounter one of these ERR_NETWORK_CHANGED errors, can you run the attached script which will simply re-run "ipconfig /all" until it sees an error, and then can you attach new_state.txt and old_state.txt to this bug?

I was waiting until I had this problem again (which I do right now), but I don't know where or how you want me to run this. 

Can you provide some more details? Is this is in the Windows Command Prompt? In Chrome? In a Linux terminal? I'm not familiar with running something like this.

Thank you, I do want to help, but I'm not quiet sure where to start. This is just slightly above my knowledge level.

> Is this is in the Windows Command Prompt?

Yes.

I've tried two separate times now to get that to work, but it doesn't do anything. I typed it on, line by line the first time, and I copied and pasted it all into the command prompt the second time, but I can't tell what it's doing.

1. Save the file
2. Run the file from the command line
3. When it exits, attach the resulting new_state.txt and old_state.txt to this bug

When I go to the directory and attempt to run the batch file (by typing 'netchange.bat', it says 

'netchange.bat' is not recognized as an internal or external command, oeprable program or batch file.

So if I'm doing it wrong, I apologize, but I need more information/direction to do what you're asking. Running batch files like this is something I haven't done before and I'm only somewhat familiar with using the command prompt. I consider it a small victory that I found the right command to change the directory after only my third attempt.

Hmm.  I haven't used Windows in a while.  I imagine the netchange.bat file should get saved to the "Downloads" directory and perhaps you can change there using the "cd Downloads" command.  You should be able to use the "dir /p" command to verify the netchange.bat file is present.  To run the netchange.bat command you can probably just type "netchange".

When you download netchange.bat, on Chrome's download bar entry for netchange.bat, there should be a "Show in folder" option.  You could click this and then perhaps double-click the netchange.bat item to execute it.

The file doesn't run when I double-click on it, nor does it run when I try to run it through the Command Prompt. Like I said, I know how to change the directory. But Command Prompt gives me the error I provided last time.

When you encounter these frequent ERR_NETWORK_CHANGED errors, can you run "ipconfig /all" at the Command Prompt until you notice the output changes, then attach the two different outputs to this bug?

I have a before and after captured in one text file. But, before I send this out, is there any information I should delete or obscure before I send this out over the internet for privacy sake? 

It may contain your computer's MAC and IP address.  If you're more comfortable emailing them to me (rather than posting on this public bug), feel free, my email is pauljensen@chromium.org.  I can also restrict this bug so it's not public.

I don't see any differences between the two runs of "ipconfig /all".  Assuming you ran the first one before the ERR_NETWORK_CHANGED showed up, and you ran the second one after the ERR_NETWORK_CHNAGED showed up, that would indicate that some temporary change occurred and then flipped back to it's original state.

That is what I did.

Is it possible that it's hardware and not software? Could this be bad RAM or something in a Windows 10 update not playing well with my system? It is odd that it's specifically Blink-based browsers, but if you're running down other possibilities...
