When first installing the Ubuntu operating system when prompted to set up a wifi network I entered the info for my phone's mobile hot-spot (Thank God) and I have been using that. First I was only connected to wifi when i was within the non GUI terminal environment but when I donwloaded firefox all of a sudden I am able to connect to wifi on the desktop environment now but I am unable to switch to my home network now (since I dont want to use all my data obviously) and it still says no wifi adapter found please help! Below are some entries related to my question:

Solution:

Shell Script:

Created wifi_setup.sh script using nano text editor. Added:

sudo nmcli device set wlo1 managed yes

Executable Script:

Made the script executable:

chmod +x wifi_setup.sh.

Startup Configuration:

Set the script to run during system startup. Path: /home/jorjortaylor/wifi_setup.sh.

Note: I avoided restarting NetworkManager at any point as it caused my WiFi interface to revert to an unmanaged state.

This approach might not be conventional, but it worked when other solutions failed. Sharing this in the hope it helps others facing similar challenges.
