So my bluetooth is showing a STATUS_DEVICE_POWER_FAILURE error.
1) When I downloaded Intel's Driver Update Utility, it claims I have installed driver 188.8.131.52 (which is untrue as far as I can tell). When I click to download and update, it downloads BT_18.16.1_64_Win10 which is what is already installed apparently. It notes this in the installation process. See pics:
So my first question: Is this is the most recent driver version?
2) As noted, I'm receiving STATUS_DEVICE_POWER_FAILURE. I had seen a note in another thread indicating that some units may be defective (see /thread/61704 here). In particular, it is alleged that TA# G86254-001 may be defective. My unit is TA: H42623-002. Another user claims this unit is not defective. My unit initially worked but now it is not.
3) I've attempted reverting to older drivers. In particular, I've attempted to install:
Are there any others I can attempt? None of these have resolved the problem.
OS is Windows 10 64 bit.
I rolled back to driver version 17.1.1524.1353.
It still does not work but gives me a different error code:
"Windows has stopped this device because it has reported problems. (Code 43)"
This error can be caused by a Hardware problem, so it is recommended to check about it with the http://www.intel.com/content/www/us/en/support/topics/oems.html Computer Manufacturer Support.
As you suggested, other users have been able to resolve this by uninstalling and deleting the driver from Device Manager, then installing older drivers, or deleting the Intel generic drivers and allowing Windows® to use the OS built-in (In-Box) BT driver.
The recommended version of https://downloadcenter.intel.com/download/25840/Intel-PROSet-Wireless-Software-for-Bluetooth-technol... Intel® PROSet/Wireless Software for Bluetooth® technology for Windows® 10 and the Intel® Dual Band Wireless-AC 7260 is 18.16.1.
For further assistance, please let us know if this is the adapter that came from factory with your PC.
