I have a Intel Dual Band 7260 PCi - my bluetooth connection to sony nusic center CMT-SX7 is lost evry time sony center goes to standby and I need to reconnect mannually. Previsously I had Atheros PCI card and had no problems with it (sony center always was connected or reconnected automatically) so I assmume the problem is with Intel card / drivers. Please help to solve it.
What versions of the Intel Bluetooth and WiFi drivers do you have installed? Here are links to download the latest. If you don't have these, I recommend that you install them...
https://downloadcenter.intel.com/download/27195/Wireless-Intel-Wireless-Bluetooth-for-Windows-10 Download Intel® Wireless Bluetooth® for Windows® 10 v20.0.0
https://downloadcenter.intel.com/download/27203/Wireless-Intel-PROSet-Wireless-Software-and-Drivers-... Download Intel® PROSet/Wireless Software and Drivers for Windows® 10 v20.0.2
I recommend that you install the Bluetooth driver package before the WiFi driver package.
Hope this helps,
There are reasons why you cannot change your wireless card:

Completely uninstall the versions you have, reboot and then install the latest per my message above.

Right-click on the Windows Start button and select Apps & Features. Find the entries for Intel Wireless Bluetooth and Intel PROSet/Wireless Software. Uninstall both packages. Reboot. Install the latest Bluetooth package and then install the latest PROSet/Wireless package.
