Why is Wi-Fi shutting down?

Could you please elaborate on the reason why Wi-Fi is shutting down? Is it due to technical issues or a larger scale problem? Are there specific locations or devices that are affected? Has there been any official announcement or warning regarding this shutdown? And what does this mean for those who rely heavily on Wi-Fi for their daily activities? Is there a timeline for the restoration of Wi-Fi services? Finally, are there any alternative methods or workarounds that we can use until the issue is resolved?
