I am running Parrot Security 4.5 but also used previous versions but there is a lack of firmware for Qualcomm Atheros QCA9337 Wireless Adapter. For this the Wireless Adapter cannot enter into the monitor mode or in the promiscous mode & for this I can’t perform any wireless penetration test through it.
running the ‘dmesg’ command as a root user I have came to know that the missing firmware and driver related issues are given below. I also suggest you to add all third party or non-free firmware for all wireless adapters. Then it will be the best OS ever. The missing files via dmesg command
