The reason different hardware gets mentioned with different solutions is precisely because there’s no single underlying issue at play here, perhaps aside from setting your regulatory domain correctly as outlined in the official post-installation guide; desktop environments are less likely to be causing the problem, but may sometimes affect how you fix it. A good start for troubleshooting would be uploading you CachyOS bugreport (sudo cahcyos-bugreport.sh).
Output confirms that the regulatory domain has been successfully set (per guide, look at the country line here), so that should be taken care of now. If issues still continue, as I said, upload a report generated by sudo cachyos-bugreport.sh to help with troubleshooting.
Only one’s country regulations can be active at a time, uncommenting everything will just make the last entry take effect. Ideally, you should change your settings when traveling for optimal performance and compliance, although having it wrong isn’t likely to lead to major trouble.
So, if I traveled to any other country it is supposed to work (generally speaking) or at least is supposed to work though I am in another country other than the one specified?
Yes - it might degrade performance, but should work okay. I think setting up a hotspot might theoretically land you in trouble, but chances of that are very low.
Then please post a bug report as I’ve suggested; it’s effectively impossible to troubleshoot this without more details about your hardware. I can attest to this not being a general issue with CachyOS as I’ve been using wi-fi without such issues.
I searched some AI and it suggested to install something but installation failed as follows:
