RE: Latitude E5520 Bluetooth Driver install
Thank you for writing to the Dell Community Forum.
Please go to the system BIOS > Settings > Wireless > Wireless Switch & Wireless Device Enable and enable the WWAN, WLAN and Bluetooth. Refer to this link http://dell.to/2soIY0P download the Bluetooth driver, turn off the wireless switch and turn it back on then install the driver.
Kindly get back if there are any further queries.
