I installed Kali Linux as the second operating system for Windows 10. Now I need to configure the network adapter. Found etho network missing. When installing Kali Linux, there was only one problem: The: regulatory.db firmware file is missing. This problem was ignored by me, although during the installation it was suggested to install this file from a usb media. I'm afraid this file is the problem. If someone knows how to install it in an already installed Kali Linux, please help. As far as I know, it should be in / lib / crda along with regulatory.bin.
