A router is a network device that forwards data packets between different networks, ensuring that the information finds its way to its destination efficiently and securely. It connects private networks, such as the home network, to the internet and allows multiple devices to share a single internet connection. In the smart home sector, the router plays a central role, as it is responsible for the communication and control of networked devices.

What does router mean?
The term "router" comes from English and means "to find a way" or "to guide." A router forwards data packets within networks and uses routing tables and protocols to decide how and where the data should be sent. It is the central connecting element in a network, enabling both data exchange within a local area network (LAN) and the connection to the internet. Routers are typically found in homes and businesses and are necessary to make the internet accessible to multiple devices simultaneously.
Frequently asked questions
What exactly does a router do?
A router receives data packets from a network, analyzes the destination address, and forwards them to the appropriate destination network. It uses routing tables to determine the most efficient route for the data packets to reach their destination. In a home network, the router also distributes the internet connection to various devices connected via LAN or Wi-Fi. In the smart home sector, the router is indispensable, as it enables communication between networked devices and control over the internet.
What is the difference between a router and a modem?
A modem is a device that connects to the internet by converting the ISP's digital signal into a readable signal for the home network. A router, on the other hand, distributes this connection across the home network, allowing multiple devices to use the connection simultaneously. These days, modems and routers are often combined into one device, which is why the terms are sometimes used interchangeably, even though they technically perform different functions.
What types of routers are there?
There are different types of routers designed for different applications:
- Wi-Fi routers: These devices offer both wired and wireless connections and are most commonly found in homes.
- Mesh routers: Consist of several devices that work together to create a large Wi-Fi network and eliminate dead spots.
- Modem-router combo devices: These combine the functions of a router and a modem in one device.
- Industrial routers: Designed for use in industrial environments, they offer special features such as VPN, increased security, and greater robustness.
How do you secure a router?
Router security is important to protect your home network from unauthorized access. Here are some security tips:
- Change the default password and use a strong, unique password.
- Enable WPA3 encryption (or at least WPA2) for the Wi-Fi.
- Disable remote management of the router if it is not needed.
- Keep the router's firmware up to date to close security vulnerabilities.
- Use a separate network for IoT devices to secure the main network.
What does dual-band router mean?
A dual-band router is a router that supports both the 2.4 GHz and 5 GHz frequency bands. The 2.4 GHz band offers greater range, but is more susceptible to interference and has limited speed. The 5 GHz band enables faster data transfers and is less susceptible to interference, but has a shorter range. Dual-band routers therefore offer flexibility, allowing the user to choose between range and speed depending on their needs.
