This could be due to missing, outdated, or incompatible drivers, or drivers that are not properly installed or updated. Driver conflicts can affect either the Bluetooth or the Wi-Fi function of the network adapter, or both, and may cause failure or poor performance.
• Environmental factor: The network adapter may have an environmental factor that affects its signal strength or quality. This could be due to interference from other wireless devices, physical obstacles, or electromagnetic fields. Environmental factors can affect mainly the Wi-Fi function of the network adapter, and may cause failure or slow or unstable connections.

Possible solutions for network adapter failure

Depending on the cause of the network adapter failure, different solutions may be applicable. Here are some general steps that the user can try to fix the network adapter failure on their HP ProBook 450 g5 laptop:

• Check the hardware: The user should inspect the network adapter for any visible signs of damage, such as cracks, burns, or loose connections.
