Diagnosing a network adapter to determine if it has driver issues can be essential for resolving network connectivity problems. Network adapters connect your computer to a network, and the drivers are software that allows the operating system to control these adapters. When drivers are outdated, corrupted, or incompatible, your network functionality suffers.
