AC-9260: The miniport has failed a power transition to operational power

HP AY168SA, stock configuration with replacement wifi card & clean install of Windows 10

Using the latest Intel PRO set drivers (March 20).

Using latest HP BIOS & drivers.

With secure boot turned on, the error is very inconsistent and the event log shows a variety of obscure error messages.

With secure boot turned off, the card fails to initialise with "The miniport has failed a power transition to operational power" (followed by a variety of assorted error messages) after the machine has been in stand by. restarting the machine brings the card back online. Uninstalling and reinstalling the card, or disabling it, causes the machine to hard reset.

Hello kimthefirst,

Thanks for posting in our community. Your thread has been moved to .

Please notice that just like any other device, not all wireless adapters are physically and electrically compatible with all systems. Intel does not recommend end users install or upgrade the various Intel® Wireless Adapter; you should always contact the Computer Manufacturer Support or its authorized representative to check which adapters are supported by your computer and replace it with them whenever possible. For more information, please check the following advisories:

- https://www.intel.com/content/www/us/en/support/articles/000005687/network-and-i-o/wireless-networki... Regulatory Information Regarding Hardware Installation or Upgrade

However, please make sure the power saving options for the wireless adapter are set to maximum performance. Right click on the battery icon and select Power Options > Change plan settings > Change advanced power settings > Wireless Adapter Settings > Set Power Saving Mode to Maximum Performance on both "On battery" and "Plugged in" options.

Additionally, please disable the https://www.intel.com/content/www/us/en/support/articles/000005585/network-and-i-o/wireless-networki... wireless adapter advanced setting "U-APSD support", test waking from sleep mode and let us know the results.

Best regards,

Hello!

I've tried configuring the power management as suggested, this seems to have had little effect.

Furthermore, sometimes when the wireless deactivates, it will not re activate even if I pull the battery, press and hold power button, etc - so in a way it might be worse now but this could all be down to random chance as the problem is reasonably inconsistent to start with. Sometimes it will suspend / resume or turn off / on without issue, sometimes not.

The device is definitely remembering it's previous state when powered down but I can see no pattern other than that it is definitely related to powering the device off and on. The problem will not occur if the laptop is not turned off. I have used it for 30 hours straight with zero problems, closed it, re opened it, and then had no wifi.

Cheers!

Hello kimthefirst,

 

 

Thanks for your reply.

 

 

Checking the http://h10032.www1.hp.com/ctg/Manual/c05087748 Maintenance and Service Guide for your system (page 62), we noticed Intel® Wireless-AC 9260 is not part of the recommended spare WLAN modules.

 

 

As explained before, it is highly possible the issue is caused by compatibility. At this point we recommend https://support.hp.com/us-en/contact-hp contacting HP* for further assistance.

Dear Kimthefirst!

Have you found a solution? I have almost the same problem.

The difference is that my Intel wifi adapter is in recommended list of wifi modules of my HP pavilion laptop.

Many thanks in advance!
