  • If mobility and convenience are your priorities, then a WiFi solution may serve you better, especially with advanced routers that support higher speeds.

Ultimately, it’s about finding the right balance and understanding that both systems can coexist, offering unique strengths that cater to different aspects of our increasingly connected lives.

What is the main difference between LAN and WiFi?

The primary difference between LAN (Local Area Network) and WiFi is the method of connectivity. LAN typically uses wired connections, such as Ethernet cables, to link devices within a specified area, like an office or a home. This wired setup allows for stable and consistent connectivity, making it ideal for tasks that require high-speed internet access.

On the other hand, WiFi utilizes wireless signals to connect devices to the internet. This offers the advantage of mobility, allowing users to move freely while staying connected. However, the wireless nature of WiFi can introduce variability in speed and reliability due to potential interference from other devices, walls, or distance from the router.

Is LAN faster than WiFi?
