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

    Same here on DELL Inspiron 16 7610.

    This subject must not dive because we need a procedure to follow...

    Nothing to add, I just have the same issue on my Lenovo Thinkbook 16p.

    After waking up from sleep, it works fine for a few seconds, then I have no WiFi and some apps take ages to load. Right clicking on an icon on the taskbar does nothing.

    Re-installing w11 did nothing, the issue persists.

    Please address this, as it basically renders the Sleep functionality useless.

    Identical problems here, DELL XPS 15

    Ok so I solved the problem I described above.

    Essentially I went through Lenovo's Warrantee Support team and emailed back and forth with a technician. What helped them identify the problem was when they asked me to:

    4.) Please run the hardware diagnostics test. See below for instructions:
    Turn the machine off and then back on. Before you see the Lenovo splash screen, start tapping the F10 key repeatedly until it takes you to the diagnostics page. Select RUN ALL then select FULL UNATTENDED TEST. Once completed, the diagnostics test will provide you with a FINAL RESULT CODE. Please write the final result code down, or take a picture of the results along with the date the test was ran and reach back out to us so that we can validate the results and replace the part that may be listed.

    I did this and sent them a picture of the test and from that information they were able to diagnose that "I believe the system board is malfunctioning / defective.".

    Lenovo sent me a box to mail the computer in. I mailed it in and they sent it back quickly. The problem I described in my previous post no longer happens.

    Hopefully this resolution will help other people.

    Note: My computer was still within its 1 year warrantee so I believe that made process of getting support easier.

    I have the same problem with a Dell Precision 5540:

    After PC went to sleep and logging in again:

    • Brave browser:
      • ERR_NETWORK_IO_SUSPENDED error when trying to load/reload a site
      • Scrolling/selecting text in a previously loaded page doesn't work
      • Switching tabs is usually still possible
    • Windows:
      • Pressing the Win button on the keyboard or trying to open the start menu with the mouse doesn't work
      • Teams/Outlook report that they are offline
      • Sluggish behavior of whole system

    After a few minutes, the above problems go away and I can work normally again. But sometimes (after everything has been working fine for a while) it's also happening that all of a sudden everything mentioned above happens again (without the PC going to sleep or being locked meanwhile).

    Just to remind everyone in this post.

    This issue isn't a Surface issue. It exists in lots of PCs and laptops from different brands including self-built computers.

    And please can the people who advise that one updates the PC just stop that?

    We all work on PCs and get that updates are important. All pf us have our machines updated naturally.

    We have an issue at hand that probably requires someone who knows much about the backbone of Windows and software in general to pitch in.
