Routers act as the routing maestros, executing the task of transferring data packets across networks to various devices. However, do you possess comprehensive knowledge about this Internet device?

Routers function as routing devices, efficiently transferring data packets across networks to different devices. While their primary role is to establish network connections, this article unveils 10 additional functionalities that routers can bring to your network.

If a Modem serves as the source device with the task of connecting household devices to the Internet service provider, then the Router is the intermediary connecting the modem and devices within the household.

In today's era, Wireless Routers are extensively employed, not only for network connectivity but also for managing and ensuring more robust network systems. Especially in the business environment, wireless routers become more indispensable than ever. The ten features mentioned by Mytour below are expected to enhance your understanding of home networks.

10 Unexpected Functions of Routers

1. Encryption and Security Capabilities

If you broadcast Wi-Fi, it's imperative to set a password to safeguard the connection and mitigate the risk of unauthorized usage. Currently, numerous encryption standards enhance Wi-Fi network protection, such as WEP. However, in recent times, WPA2 has emerged as the gold standard, effectively countering any malicious software attempting to crack the security of your home Wi-Fi.

2. MAC Address Filtering

Each computer or device accessing your home Wi-Fi is identified by its corresponding MAC address. Therefore, it's up to you to decide whether to block or allow device access. This is also considered one of the most effective ways to safeguard your Wi-Fi.

3. Port Forwarding Configuration

In simple terms, each data packet typically arrives at a predefined port, and you have the option to control and allow them to switch ports if needed. While this is a good security measure, in reality, it's not a straightforward method for beginners.

4. Network Management with QoS

QoS is a feature that allows prioritizing bandwidth for a service listed in the hierarchy over others. This feature is mainly utilized when your network encounters overload situations. Under normal circumstances, it's advisable to leave it on automatic mode.

5. Optimal Broadcast Channel Selection

If you reside in an area saturated with Wi-Fi signals from routers configured similarly, switch the broadcast channel to minimize interference. However, exercise caution as some older devices may not pick up signals from your chosen channel.

6. Choose the 5GHz Band

Almost all modern routers today support the Wifi 802.11ac standard, providing support for the 5GHz band for superior speed compared to 2.4 GHz. This is an excellent solution for avoiding signal interference and ensuring network speed, but only a few recent laptop and smartphone models support this frequency band.

7. File Sharing

Modern routers, especially wireless ones, often come equipped with USB 3.0 ports allowing access and content exchange from any device within the network. This is also considered a perfect data backup solution for contemporary router setups.

8. Guest Mode

In simple terms, this mode allows outsiders to use your home network at a specified speed and for a set period. Those enjoying the free access are not permitted to abuse your bandwidth, and most modern routers support this feature, making it easy to implement on your home network.

9. Parental Control

This mode proves to be quite handy for routers. It empowers you to manage numerous aspects on the network or control internet usage time for young ones. For game-loving students, this is the optimal solution you can apply.

10. Mobile Management

While not yet widespread, this is the endeavor of router manufacturers in an era where everyone possesses a 3G smartphone. It enables direct connection to the home network, management, and control through your smartphone.

Here are 10 functionalities of Routers that you might not be aware of. If you're using multiple Wi-Fi networks, you may want to check out articles guiding password changes for FPT, Tenda, Viettel, or various modem providers on your computer or laptop.

During usage, if you experience weak Wi-Fi speed and insufficient coverage throughout your home, it could be due to improper setup and usage of your Wi-Fi network. Try implementing the Wi-Fi boosting methods recommended by Mytour.

Frequently Asked Questions

What essential security features do modern routers provide for home networks?

Modern routers offer essential security features, including encryption capabilities like WPA2 to protect your Wi-Fi from unauthorized access. Setting a strong password is crucial for safeguarding your network against potential threats.

How does MAC address filtering enhance the security of my Wi-Fi?

MAC address filtering enhances Wi-Fi security by allowing you to control which devices can connect to your network. By blocking or allowing specific MAC addresses, you can effectively limit unauthorized access to your network.

What is the function of the Guest Mode feature on routers?

The Guest Mode feature allows visitors to use your home network at a specified speed and for a limited time. This ensures that guests can access the internet without consuming your bandwidth or compromising your main network's security.

Why should I consider using the 5GHz band on my router?

Using the 5GHz band on your router can significantly improve your internet speed and reduce signal interference. However, it's essential to ensure that your devices support this frequency for optimal performance.

How does Quality of Service (QoS) manage bandwidth during network congestion?

Quality of Service (QoS) helps manage bandwidth by prioritizing certain services over others during network congestion. This feature is crucial for maintaining optimal performance when multiple devices are using the network simultaneously.
