Random ERR_NETWORK_IO_SUSPENDED in Windows applications (network itself *is* working)

Quite often Windows applications are stuck (frozen) with error ERR_NETWORK_IO_SUSPENDED.

(Typically observed in Chrome, but impacts also any other application, e.g. Edge)

When:

  • after returning from sleep mode
  • *but also* at random time

For how long:

  • several minutes
  • then the applications automagically resume to normal behaviour

What is impacted:

  • all Windows applications at the same time
  • except WSL, that is *not* affected (e.g. I can do a curl without any problem)

Network itself is not the cause!:

  • other devices in my LAN still have access to Internet during the incidents
  • WSL still has access to Internet too!

I had the impression I could have solved the issue after forcing a downgrade/upgrade of Windows, but the problem is there again (maybe since the last Windows update). Windows version is up to date. Already tried to reboot many times, of course. To no avail.

This issue is extremely frustrating, when you are are stuck in the middle of a sentence and have to look at your laptop during long minutes before being able to finish typing. (BTW, got stuck twice while typing the present question!)

I'm quite desparate with this. Don't even have a clue on how to investigate. Did not find anything interesting in Event Viewer.

Context:

  • Surface_Book_3_1900
  • Windows 10 Home 10.0.19044

    I am having the same issue on my Lenovo Thinkpad X1 Extreme Gen 3 (Windows 11).

    For me, the problem consistently happens when coming back from the computer sleeping.

    I will get the error message in Chrome:

    "Your connection was interrupted. Your computer went to sleep. err_network_io_suspended."

    What is interesting is that immediately after opening the computer from sleeping, the internet will work fine for about 30 seconds or so, but then the internet will stop working and I will get the above error message. The problem resolves itself in after some time (anywhere between 1 minute and 10 minutes). The internet will start working again and Chrome pages will start loading like normal.

    Very frustrating! Any ideas on what is going on here?

    Why is it also happening to other people that are using ASUS laptops? I also want to fix the problem without the need to restart the computer.

    I do have an Asus laptop and that's where it's happening. But it started ith me months ago after a Windows update I assume.

    I have a similar issue with my Surface Studio 2 (Insider Win 11) when using hibernate or sleep my ethernet connection becomes very slow (50mibps from usual 380mibps), I have found changeing the ethernet port on my router/modem to another ethernet port (resetting my dhcp ip) solves the issue. This has been an intermittent issue since last year.

    Seems to be a known error and apparently started on Jan 2022... I got a brand-new ASUS laptop 2 days ago and facing this issue, the ASUS support apparently copied and pasted the instructions above provided by Microsoft agent... and Yes is fully updated.

    What I'm doing as a workaround is to every time that I've done with whatever I'm doing, just shut down the laptop, I used to hibernate like the rest of the users (That's how should be) on my previous laptop without having this issue, that being said until Microsoft provide a patch or a real solution rather than the good old "hit restart" you might need to consider turning off your laptop every time you are no longer using it.
