How can i downgrade my kernel for parrot OS

The issue is im using a usb wifi adapter which is (Realtek 80.11n With Driver Rt8192cu).I have tried everything but none of them work. And when research about the issue they say maybe the kernel issue/bug is it. So then i boot my (kali linux 2019.2) with the kernel - (kali 4.19.0-kali4-amd64 #1 SMP Debian 4.19.28-2kali1 (2019-03-18) x86_64 GNU/Linux). And it my wifi adapter worked very well. So can anybody help me with this issue or maybe anyone can tell how can i downgrade my kernel when i try to download from APT/SYNAPTIC it says not avaliable…,
Please help me out guys.

Welcome to the forum.


sudo apt update

You can use apt command, or Synaptic, to search for other kernel versions. Search for

apt search linux-image

Then, for example:

sudo apt install linux-image-4.19.0-6-amd64

Installs Linux Kernel 4.19 64bit. You can select it at the boot menu.

Have you tried this downgrading the kernel? If yes is there any issue on the latest version of Parrot?
My issue is that I get random freezes on the latest kernel in all distros. The kernel 4.19.0 works great for me. Similar to your issue, I did not had any issue on 2019.2.
