1. After the update, I'm not getting my wireless card to work in Windows. My windows 7 detects my wireless device in device manager. I've reinstalled, disabled/enabled the wireless device, but of no use. "ipconfig" shows that media disconnected. I've added NETDOWN='no' in "/etc/default/halt", but of no effect.

2. The maximum volume in Kali is much lower than that of windows (Both the inbuilt speaker and with an earphone). So to watch a properly ripped video, I have to login to windows, watch it and switch back to kali.

One more thing, I currently have the default graphics driver nouveau. Since I've dual graphics, I want to try the bumblebee. Is there anything I should know or be careful of, before proceeding to that? As I've read at many places, that after installing the nVidia drivers, they were not able to login to their Linux.

System Details:
Lenovo Z50-70
Core i5, 12 GB RAM, 2GB nVidia 820M along with Intel HD graphics.

1. I think there is no connection of kali with your windows while accessing your wifi driver. There might be some other reasons due to which your wireless is not working.
2. For speaker i am not sure about the solution but may be you should play with alsa tools or you can configure it through HDAJackRetask.
3. You get the nouveau driver by default in linux and after that if you want to install nvidia drivers than here is the link you can follow.https://forums.kali.org/showthread.p...Optimus-laptop .

I am using nvidia in my lenovo Y50 with the help of this guide and its working fine with regular updates.
I hope this will help
