Hi,

Thank you for replying with the status of the issue.

You may try the below methods:

Method 1: Run the SFC.

Follow the below steps:

1. Open Command Prompt.

2. Select “Run as Administrator”.

3. Type “sfc /scannow” without quotes and hit Enter.

Now check for the issue.

Method 2: Run the DISM Tool.

If the issue persists, I would have you run the DISM tool to check the system health and will try to restore the files.

1. Click on 'Start'.

2. Enter 'Command prompt' in the Search box.  

3. In the list of results, swipe down on or right-click Command prompt, and then tap or click 'Run as administrator'. 

4. In the Administrator: Command Prompt window, type the following commands. Press the Enter key after each command:

DISM.exe /Online /Cleanup-image /Scanhealth 

DISM.exe /Online /Cleanup-image /Restorehealth

To close the Administrator: Command Prompt window, type Exit, and then press Enter.

Note: The tool might take 15-20 minutes to finish running, so please do not cancel it.

Method 3:

If the issue persists, I would suggest you to try resetting TCP/IP. Check if it helps.

1. Open command prompt, right-click in the left corner when theStart window appear and select command prompt (admin).

2. At the command prompt, copy and paste (or type) the following command and then pressENTER:
netsh int ip reset c:\resetlog.txt

Note: If you do not want to specify a directory path for the log file, use the following command:

netsh int ip reset resetlog.txt

3. Reboot the computer.

Thanks for the info.  

I've had a week without this error, but after a Windows Update last night, it returned.  I tried all the steps you suggested, but SFC /Scannow found no errors, but resetting the TCP/IP did work.  However, I'm guessing this is no different to the "netsh winsock reset" I've been doing anyway, which clears the issue for a while but then it randomly returns.

Again, the same thing happened - when turning on my laptop this morning, I knew the problem had returned as the Wifi symbol before the password login screen had that funny circular symbol on it - this time I took a picture of it (attached below).  What does it mean?
