We regret to inform you that we don't provide support for custom wireless integrations. The Intel® Dual Band Wireless-AC 8265 has over 7 different versions, only your computer manufacturer will be able to tell you which exact models will be compatible with your system.
If your wireless hardware upgrade was pre-approved by your computer manufacturer, they will be the ones who can provide you with support.
From our end we can recommend making sure that you're using the latest Wireless and Bluetooth* drivers. You will also need to make sure that antenna number two is properly connected, as this antenna is shared between Bluetooth* and Wireless as needed.
You may also make sure that your Bluetooth* AMP setting is enabled, as this should improve your Bluetooth* connectivity and decrease interference.
@ferentes - What is the OS? What version of BT driver you have on your system currently?
