When I tried to install Kali Linux, I encountered a little issue on its configuration. In
Detect network hardware, it is indicated :
Some of your hardware needs non-free firmware files to operate. The firmware can be loaded from removable media, such as a USB stick or floppy.
The missing firmware files are iwlwifi-8000C-21.ucode iwlwifi-8000C-20.ucode iwlwifi-8000C-19.ucode iwlwifi-8000C-18.ucode iwlwifi-8000C-17.ucode iwlwifi-8000C-16.ucode iwlwifi-8000C-15.ucode iwlwifi-8000C-14.ucode iwlwifi-8000C-13.ucode
Is it because Kali Linux hasn't been well installed on my external drive? What do I have to do?
P.S. So far the network configuration can't be autoconfigure. The only way it works is if I configure it manually.
