WiFi not automatically connected on startup, and no automatic switch between WiFi and ethernet when available

I am running Ubuntu 20.04.4
It used to work fine, until 3-4 days ago I installed Cape2 to create a cuckoo sandbox, using this script : https://github.com/doomedraven/Tools/blob/master/Sandbox/cape2.sh

Afterwards, there was an error on startup ("Failed to start Anonymizing overlay network for TCP"), which has to do with tor, so I disabled services that had been installed with cape2.sh, such as tor and suricata

However, afterwards on startup the WiFi or the ethernet, if plugged in, are not managed properly I think, since even though the laptop shows that I have internet connection, I can not browse nor do anything that requires Internet such as e.g. apt update and upgrade.

The only thing that I can do now is every time run
$ sudo dhclient wlp3s0
(this is the name of the WiFi network), or
$ sudo dhclient enp0s25
(ethernet)

In summary, I would like that the connection to WiFi be automatically done on startup, instead of having to run dhclient every time, and to automatically switch to ethernet if this is connected: i.e. the default behaviour on a fresh ubuntu installation.

Thanks a lot!

Step 4
Lenovo Thinkpad T430
I'm trying that the connection to the wireless "wlp3s0" be automatically done on startup, instead of every time having to run
$ sudo dhclient wlp3s0
Also, that if the ethernet cable "enp0s25" is plugged in, that the connection switches to it, instead of having to run
$ sudo dhclient enp0s25

Step 5
Ubuntu is installed and running from a harddisk
