What I need from you is a real-time remote session (Zoom, TeamViewer, or your preferred secure tool) to: • diagnose why the Wi-Fi interface is blind • walk me through any Terminal commands, SMC/PRAM resets, or network-interface reinstalls required • verify that the Mac can once again scan, join, and hold a stable connection I’ll stay on the working computer throughout our session for screen sharing and chat, and I can reboot the faulty Mac as many times as needed. ...

I have an Ubuntu-based box with two physical interfaces: the wired port will face a public network, while the built-in Wi-Fi card (or any other you advise) will broadcast a private hotspot.
