⚠️ Attention: If the icon Wi-Fi in the settings it is completely gray and inactive (does not switch), this may indicate a critical failure of the module or its physical damage after the device was dropped.
It is also worth checking if the mode is enabled Airplane mode, which blocks all radio signals. If the wireless icon doesn't appear within a minute after disabling this mode, a deeper system reboot is required.
iOS software crashes and device reboots
operating system iOS is known for its stability, but the accumulation of temporary files and network service cache can lead to driver freezes. A standard reboot often solves the problem when the network is unavailable due to a software conflict.

Physical damage and service
If none of the software solutions help, there's a high probability of physical damage to the antenna module or the cable inside the case. Drops, exposure to moisture, or simply long-term use can cause the contacts to become loose.
Symptoms of hardware failure include: a gray, inactive icon Wi-Fi, constant connection drops near the router, and excessive heating of the rear panel near the antenna. In such cases, diagnostics at an authorized service center are required.
