I am sorry having abandoned this thread for the last 2 weeks. I could not remove the hardblock on my laptop's internal wifi card, but today I found an answer suggesting me to disable it using the code

 sudo modprobe -r wl

and it worked!
So, I blacklisted the module and am able to use wifi
Thank you all for helping out!
