It also provides individualized encryption for each device, making it more difficult for hackers to intercept and access your data. Furthermore, WPA3 includes enhanced security features, such as password-less authentication and improved brute-force attack resistance, to keep your network safe from unauthorized access.
What is the difference between the 2.4GHz and 5GHz frequency bands?
The main difference between the 2.4GHz and 5GHz frequency bands is the range and speed they offer. The 2.4GHz band has a longer range and can penetrate solid objects more easily, making it better suited for devices that are farther away from the router or need to connect through multiple walls. However, it’s more prone to interference from other devices and has slower speeds.
The 5GHz band, on the other hand, offers faster speeds and is better suited for devices that require high-bandwidth connections, such as smart TVs and gaming consoles. However, it has a shorter range and is more susceptible to interference from physical barriers. Most modern devices can connect to both bands, and you can configure your router to use one or both frequencies depending on your specific needs.
Should I enable Quality of Service (QoS) on my router?
Enabling Quality of Service (QoS) on your router allows you to prioritize certain types of internet traffic, ensuring that critical applications get the bandwidth they need. For example, if you have a lot of online gamers or streamers in your household, you can allocate more bandwidth to those devices to reduce lag and improve performance.
