WiFi disappear

Intermittent Wi-Fi connectivity issues on your iPhone may actually be rooted in the router rather than a problem with the iPhone itself. The fluctuating appearance and disappearance of the Wi-Fi signal are often symptoms of an unstable or malfunctioning router. To address this, it's advisable to have the router inspected by a reputable internet service provider (ISP) or a technician. By having the router examined by professionals, they can identify and rectify any issues within the router's settings, hardware, or overall functionality, ensuring a more stable and consistent Wi-Fi connection for your iPhone and other devices.
