Understanding Network Adapters
Before we dive into the troubleshooting process, it’s essential to understand what a network adapter is and how it works. A network adapter, also known as a network interface controller (NIC), is a hardware component that enables your laptop to connect to a network. It can be a physical card, a built-in chip, or even a USB device. The network adapter’s primary function is to transmit and receive data between your laptop and the network, allowing you to access the internet, share files, and communicate with other devices.
Types of Network Adapters
There are several types of network adapters, including:
Wireless network adapters, which use radio waves to connect to a network
Wired network adapters, which use Ethernet cables to connect to a network
Bluetooth network adapters, which use Bluetooth technology to connect devices
Mobile broadband network adapters, which use cellular networks to connect to the internet
