BIOS update in my HP Pavilion g6 Laptop

Is there в way to update my BIOS of HP Pavilion g6 from Ubuntu 15.10? Hp - released the Windows BIOS update only for 7. I don't have windows installed in my laptop right now. So is there any way to update the BIOS through Ubuntu. I want to update my BIOS since my laptop is having WiFi issues. WiFi is not connecting sometimes and в reboot is required. I had the same problem when i was using Windows 8. So I think it could be the BIOS problem not starting the WiFi adapter properly. Please help.
