How to install WICD on ubuntu 20.04?

I am using ubuntu 20.04 focal 64bit. Pre installed network manager is giving me headache. It suddenly drops wifi connection. On scanning again it shows no visible network. The input command

lshw -C network

gives output

*-network DISABLED
description: Wireless interface

while searching for the solution i saw WICD solves the problem but how do i install on my laptop. INPUT

sudo apt install wicd

OUTPUT

E: package 'wicd' has no installation candidate

The wicd-gtk was removed from Ubuntu 20.04 LTS repositories because of Python 2 deprecation.

But you still can install it if you download packages manually from 19.10:

mkdir -p ~/Downloads/wicd
cd ~/Downloads/wicd

wget http://old-releases.ubuntu.com/ubuntu/pool/universe/p/pygtk/python-gtk2_2.24.0-6_amd64.deb
wget http://old-releases.ubuntu.com/ubuntu/pool/universe/p/pygtk/python-glade2_2.24.0-6_amd64.deb

wget http://old-releases.ubuntu.com/ubuntu/pool/universe/w/wicd/python-wicd_1.7.4+tb2-6_all.deb
wget http://old-releases.ubuntu.com/ubuntu/pool/universe/w/wicd/wicd-daemon_1.7.4+tb2-6_all.deb
wget http://old-releases.ubuntu.com/ubuntu/pool/universe/w/wicd/wicd-gtk_1.7.4+tb2-6_all.deb

sudo apt-get update
sudo apt-get install ./*.deb
sudo apt-get install ./*.deb # second time for correct configuration

and then use it.
