Please keep in mind that we do not recommend/support custom integration of Intel® Wireless Adapters. It is advised to contact the Computer Manufacture Support to know if a certain adapter is supported by your system. These adapters can only be installed by the manufacturer or its authorized representative.
We strongly recommend to check with Dell about this, since there is a good chance that this may be due incompatibility.
In our best effort, here are some items for your consideration:
- Make sure you uninstall and delete any previous BT drivers in your PC. These may cause conflicts with the Intel adapter.
- If possible do a clean istallation of the BT driver. To achieve this, go to Device Manager - Bluetooth Radios, right click on the Intel® Wireless Bluetooth®, uninstall and delete the driver. Rescan for devices and make sure you uninstall/delete older driver versions as well.
- Make sure that both Wireless antennas as properly connected to the Wireless adapter.
I'll try to give a good clean on the system and try it from scratch again!
Would you expect the wifi antennas connection to have any interaction with the bluetooth? Due to wavelength and antennas required, these antennas should not interact, not that I know. I sure disconnected the additional small Bt card originally on the system.
The Intel® Wireless Adapters normally have 2 antennas, one is dedicated to WiFi connectivity, the other one is shared between WiFi and Bluetooth, but both are required for it to operate. It is possible to get some interference, specially if your Wireless Network operates in the 2.4 GHz band.
We would like to remind you that if the PC was not designed for your new adapter, it may not be compatible and will not work with it.
Let us know if this helps, or in case you need any additional information.
