If a WWAN device is malfunctioning, what is the priority action to check?

When dealing with a malfunctioning WWAN (Wireless Wide Area Network) device, confirming that the device is enabled in the connection manager is a critical first step. This action is essential because, even if all other components are functioning correctly, the device will not operate unless it is actively enabled by the system's software.

The connection manager serves as the interface through which network connections are controlled and monitored. If the WWAN device is disabled in this platform, it will not transmit or receive data, creating the appearance of a malfunction. Therefore, checking this setting is a logical and necessary step to determine whether the device is merely turned off rather than experiencing a technical issue.

Following this, if the device is confirmed to be enabled and still malfunctioning, further steps that might be taken could include verifying physical connections, software configurations, and drivers. However, ensuring the device's enablement should always come first as it is a straightforward check that can save time in troubleshooting.
