Hi, i'm new in the forum, my name is Arun and I'm a student. I need urgently a fix for my test in Security.

(I have read several threads about similar problems but actually i cant apply their solution)

When I installed Kali Linux 2018.1 in my Dell Vostro 5459(Vostro 14 5000 series-5459 with 6th Generation Intel(R) Core(T M) i7-6500U Processor , 8GB ram) I got a problem

It shows 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: ath10k/pre-cal-pci-000:02:00.0.bin ath10k/cal-pci-0000:02:00.0.bin

If you have such media available now, insert it, and continue.

Load missing firmware from removable media?

While I skip this step and install Kali Linux after I'm unable to perform any air attack because it doesn't show any channel in monitor mode.
