Samsung Galaxy Book Go LTE - no wifi after factory reset

After a factory reset, I had shut down a Samsung Galaxy Book Go LTE laptop in order to give it to someone else. After a couple of days, when they were trying to set it up, initial setup was not proceeding after the point where it tries to connect to the network. Checking with a 4G SIM inserted, setup proceeded, and the laptop booted up into Windows 11. But no wifi networks were being detected. The wireless networking device was being flagged in Control Panel.

So, deleted the "Unknown device" in control panel, restarted the machine - now it recognized the wifi adapter, asked to connect to the network, and worked fine.
