Loss of Wifi connectivity

[A4Apollo]

@DonI2203, Thanks for your quick response and time.

Kudos to you for trying out the steps.

Performing system restore will not modify the drivers however if there was an update which caused the laptop to malfunction. It will be reverted back.

As you mentioned you would like to roll back driver version from 19.51.0.4 to 19.40.

You can roll back the driver using the recovery manager. Uninstall the drivers from device manager and install the drivers from recovery manager.

If you don't have the recovery partition on your PC. Please contact HP support and order a set of recovery discs.

Link to contact HP.

Take Care!

Have a great day ahead! 🙂

For 48Hm the system has been stable - no visible loss of wifi.  Reviewing the steps taken - the only real change is the upgrade of the nework adapter driver --BUT --- the problem persisted after that.  Also reticked the power control boxes associated with driver.

Lets put this on back burner -if all well in a few days I'll contact to to close the case.

One final question.... many times I see this event log time-associated with the onset of the problem.  I would like to understand how to perform the op. decribed in the finals sentence as I see no such tool in Component Services .

.................

The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
{8D8F4F83-3594-4F07-8369-FC3C3CAE4919}
 and APPID
{F72671A9-012C-4725-9D2F-2A4D32D65169}
 to the user NT AUTHORITY\SYSTEM SID (S-1-5-18) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.

Hi @DonI2203,

Thank you for replying,

I appreciate your time and efforts,

I understand this is to do with System log event viewer, I would suggest you give us some more time to check if I can research on this and get back to you with more information.

I would suggest you give us 72 hours so that we can research on this and get back to with more information.

Thanks for your patience in the meantime. 

Cheers!

After 2 days problem free the loss of wifi has occured again....event logs has several enrties  including...

Intel(R) Dual Band Wireless-AC 7265 : Has encountered an internal error and has failed.

can this be an intermitent hardware fault ? 

If so I can get back to the supplier of the HP pavilion as its under warranty.

Please give your opinionThanks DonI2203
