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.

First:

sudo apt update

You can use apt command, or Synaptic, to search for other kernel versions. Search for
‘linux-image’:

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.

@Bbc
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.
