Intel AC 7260 bluetooth issue

Question

Hi All, I have a dell XPS 15 L502X model. I had installed Intel AC 7260 network card few years back. It served me well so far but since last few weeks I am experiencing constant bluetooth disconnection issues.  I thought it to be some issue with windows 10 update but microsoft tech team is not able to identify the issue. I am now suspecting hardware level issue. I did check the event viewer for system errors and I saw two warnings related to bluetooth:  The local adapter does not support an important Low Energy controller state to support peripheral mode. The minimum required supported state mask is 0x2491f7fffff, got 0x1fffffff. Low Energy peripheral role functionality will not be available Bluetooth HID device either went out of range or became unresponsive. I have tried uninstalling and reinstalling latest intel driver for this card. I have also paired the devices again but still facing issue. Would request for some resolution to this problem.

For Windows 10, please follow this below instruction. It might help you, Open up Device Manager Right-click Intel Dual Band Wireless under Network Adapters and select properties Under the Advanced tab select 802.11n/ac Wireless Mode and change the value to 802.11n

Thanks for the response. I got the issue resolved through device manager by disabling power saving option.

I had searched for the same from many similar solutions over internet but was unable to find it.

I found the option to disable power option under Device Manager -> Bluetooth -> Intel Wireless Bluetooth -> Right click on Properties -> Power Management -> uncheck "Allow computer to turn off this device to save power"
