Rolled back to old versions:
Intel(R) Wireless Bluetooth(R) 19.11.1639.649
Intel(R) Dual Band Wireless-AC 7260 188.8.131.52
I'm testing it right now and the problem seems solved: no more serious disconnects.
As before, I have also disabled for 'Intel(R) Wireless Bluetooth(R)' the "Allow the computer to turn off this device to save power" check box.
Will need a month of testing to confirm the bug is gone....
Thank you for the update. We are glad that the issue has not reappeared after the driver roll back. Feel free to contact us if you require additional support.
