Hi pomon
Thanks for detail inputs. I just started my laptop to perform these steps and I am completed surprised that wifi is working as expected (without doing anything). It's might be due to the last update. I would love to know the reason for being certain.
I confirmed that there module which is blacklisted by running ls /etc/modules-load.d/
. (No output)
Yes, I was able to use wifi in live mode without and even after installed was completed on my Solus desktop until I installed Nvidia drivers.
I am really not sure what has fixed the issue bcz I haven't done anything. Most likely the update fixed it. But, I am afraid to update my system again as last to last update messed wifi again.
