A customer, whose smartphone's screen was recently repaired, reports that the device has no internet access through Wi-Fi. The device shows that it is connected to Wi-Fi, has an address of 192.168.1.42. and has no subnet mask. Which of the following should the technician check next?
Correct Answer: A
Given that the smartphone's screen was recently repaired and now experiences issues with Wi-Fi connectivity, despite showing that it is connected to a network, the problem could be related to the internal antenna connections that might have been disturbed or disconnected during the repair process. * Internal Antenna Connections: Smartphones use internal antennas for Wi-Fi and cellular connections. If these antennas are not properly connected, the device may show as connected to a Wi-Fi network but fail to transmit data effectively, resulting in no internet access. Checking static IP settings (B) would be relevant if the device were not obtaining an IP address at all, but the device does have an IP address. Airplane mode (C) would prevent the device from connecting to Wi-Fi networks entirely. Digitizer calibration (D) is related to the touchscreen functionality and would not affect Wi-Fi connectivity.
