What is the difference between a WiFi adapter and a WiFi router?
A WiFi adapter and a WiFi router are two distinct devices that play different roles in establishing a WiFi connection. A WiFi adapter, also known as a wireless network adapter, is a hardware component installed in your computer that allows it to connect to a WiFi network. The WiFi adapter receives and transmits wireless signals, enabling your computer to communicate with a WiFi router. On the other hand, a WiFi router is a device that connects to a modem and broadcasts a WiFi signal, creating a network that multiple devices can connect to.
In a typical home network setup, the WiFi router is connected to a modem, which provides internet access. The WiFi router then broadcasts a WiFi signal, allowing devices with WiFi adapters to connect to the network. The WiFi adapter in your Dell desktop with Windows 7 receives this signal, allowing you to connect to the internet. In essence, the WiFi adapter enables your computer to communicate with the WiFi router, which in turn provides access to the internet. Understanding the difference between these two devices is essential to troubleshooting WiFi connectivity issues and setting up a reliable home network.
How do I troubleshoot WiFi connectivity issues on my Dell desktop with Windows 7?
