Having issues setting up a wireless network connection

I've been trying for days to set up a WiFi connection to my laptop but I can't seem to do it. I tried everything but still can't set it up. I am very confused on this topic, please help me.
I already configured the kernel properly.
I installed two network managers in the past as a result of my ignorance. I don't know what i have done and request your guidance for it.

Please let me know if you need more information as i don't have enough knowledge to know what information to provide for you.

there is some information i think you will need:
