A technician installs a new network adapter card in a desktop computer. After booting the system, the operating system fails to automatically configure the device. The technician checks Device Manager and sees the new adapter listed with a yellow exclamation mark. What is the MOST appropriate next step for the technician to take?
Remove the card and reseat it in the same expansion slot.
Replace the network adapter card with a new one.
Download and install the latest driver from the adapter card manufacturer's website.
The correct action is to manually install the drivers for the new hardware. A yellow exclamation mark in Device Manager indicates that Windows recognizes the hardware but cannot load the correct driver for it. The most reliable source for the correct driver is the manufacturer's official website. Reinstalling the OS is an unnecessarily drastic step. Replacing the card is premature, as a driver issue is the most likely cause. While reseating the card can resolve connection issues, the yellow exclamation mark specifically points to a driver problem, making driver installation the more direct next step.
