Hello. I use a usb wifi stick on VirtualBox Kali. There is not any problem on Windows 7, its always connected. But on Kali, its only connected as long as the wired connection is active. When i disconnect the wired connection, a few minutes later wifi disconnects and doesnt connect again until restart. What can cause the problem? I tried the upload wifi driver but not sure if i was able to do it or not. Usb Wifi Card is: Ralink 5370 Chipset.
