MacBook Pro won't connect to any wi

Hello,

I've updated my MacBook Pro with a corporate profile. Since that, I haven't been able to connect to any wi-fi network at all, not even to my iPhone via Personal Hotspot.

I've already tried and cleared all my preferred networks, renewed the DHCP lease, tried changing the Location in the wi-fi settings… I've even removed the whole SystemConfiguration folder and restarted the computer. Nothing has any effect.

I've also removed the profile after which this issue started, but this hasn't helped, either.

Every attempt to connect ends up with the message: The Wi-Fi network “Network Name” could not be joined.

When trying to use the Hotspot on my iPhone, it fails with the message: Failed to enable Personal Hotspot on “iPhone's name”.

The Wireless Diagnostics hasn't helped a bit, since it's suggesting issues related to the router — which, however, is working properly (I've got other devices connected to it, including my iPhone), and has worked properly with my Mac as well, until now.

I'm genuinely lost and don't know how to proceed. I cannot find a single discussion on the internet that would deal with this exact issue. At this moment, I can only use the wired LAN connection, with which I cannot really function properly. I'd appreciate any suggestions or help.

Thank you in advance.
