Re: I cannot install wifi and bluetooth drivers for my laptop. (dell inspiron 3521)
Welcome to Dell community!
I would like to know if you have reinstalled the operating system and trying to reinstall the drivers. If that is the case, please refer the following article for instructions to install all the drivers in the correct order: http://dell.to/Ynnsnr
If the issue persists, please let me know what exactly happens when you try to install the WiFi and Bluetooth drivers, and include any error message that appears. Also, confirm the operating system (32 or 64-bit) installed in the computer.
Thanks & Regards
