[Rishi_4]

My laptop screwed up. I've a dell inspiron 15 3521 laptop. Recently when i upgraded it to Windows 10 Bluetooth went off cos the drivers were not compatible. I then tried to install them downloading from dell.com, a message came to start Bluetooth using wireless switch. I left the issue,. then there came a bios update, i installed it, now from then my , wifi, went away. when i tried to get my service tag from cmd, i got anerror that this service is stopped. Moreover firewall service also couldn't be enabled. Please help im in great problem.

Hi,

Have you tried enabling the Wifi and Bluetooth using the fn+F2 key which enables/disables both Bluetooth and Wifi?
- If toggling the fn+F2 doesn't enable the Bluetooth and Wifi proceed with uninstalling/reinstalling both drivers.
- Go to Device Manager and uninstall the Wifi and Bluetooth drivers.
- Once both uninstalled, down load and install the drivers from Dell's Support site.
- Here's the link: http/downloads.dell.com/FOLDER03171485M/1/Network_Driver_N80VN_WN32_10.0.0.0_A00.EXE
- Reboot your laptop once the latest driver has been installed.
- If after installing the driver will still not work I would suggest running System Restore first, bring it back to an earlier date or time before the problem even happened.
- Here's how to run System Restore: http/windows.microsoft.com/en-ph/windows-10/windows-10-recovery-options
- Last option if all these will not work is to reinstall Windows 10.
