Unless you prefer living in isolation, in modern homes and workplaces, you need an internet connection. To achieve that, you need two different devices: a modem and a router.
Although both provide the service of connecting your devices to the internet, there is a significant difference in how they accomplish that.
The modem connects your home network to your Internet Service Provider (ISP),
While the router allows all your wired and wireless devices to use this connection simultaneously and communicate with each other.
Modem
A modem, short for “modulator-demodulator,” is a device used in telecommunications to transmit data between devices over communication lines, whether wired or wireless.
The modem converts digital signals from a computer or another device into analog signals that can be transmitted over the communication line. It then reverses the process, converting analog signals back into digital signals when received on the receiving end.
This is why it is called a modem, as it used to connect the analog telephone line to the digital internet, and vice versa. It translated your internet data into a format that your home network devices could use. These devices are now mostly outdated and not widely used.
Through Digital Subscriber Line (DSL) modems, your internet connection has access to 6 MHz channels or more for downloading data. As for the data you send to the internet from your devices, it typically utilizes only 2 MHz channels.
This is one of the reasons why cable internet connections tend to have much faster download speeds compared to upload speeds.
A Fiber Optic Modem
A Fiber Optic Modem, technically known as an Optical Network Termination (ONT), is a device used in fiber optic communication networks to connect optical services to a user’s home or office. The ONT’s role is to convert incoming optical signals from the fiber optic network into suitable signals for home or end-user devices. This enables users to access high-speed internet, landline phone services, and television services via fiber optics.
ONTs come in various shapes and sizes, depending on network requirements and user needs. They are typically installed within the building that utilizes fiber optic services and are connected to the fiber network. After installation, users can connect their end devices such as computers, landline phones, and television equipment to the ONT to access fiber optic services.
ONTs play a crucial role in enabling fiber optic communications and providing high-quality, high-speed services to end-users in both residential and commercial environments.
In addition, modern modems use the Dynamic Host Configuration Protocol (DHCP) to assign and manage the basic Internet Protocol (IP) address for your network. While you have private addresses on your network for your devices like computers, TVs, and phones, your internet connection has its own Wide Area Network (WAN) address on the internet.
Now, moving on to the Router:
A router is the device that connects all your devices to the internet. It plays a vital role in managing network traffic, ensuring that data packets are correctly routed between devices within your local network and external networks like the internet. Routers use various technologies and protocols to perform tasks like Network Address Translation (NAT), which allows multiple devices to share a single public IP address, and they provide features such as firewall protection and Quality of Service (QoS) to prioritize network traffic.
In summary, while the ONT connects your home or office to the fiber optic network, the router manages the flow of data between your devices and the internet, ensuring efficient and secure communication.
Router
A router is a device that connects all your devices to the internet. It plays a crucial role in connecting your devices to each other and to the internet connection device (modem) to distribute the paid internet connection to the rest of your devices at home. It can do this using Ethernet cables, Wi-Fi signals, or both.
A router creates a Local Area Network (LAN) within your home or office, allowing your devices to share files and devices like printers. The router manages all the information to and from each device and the modem, ensuring it reaches the right place.
Additionally, the router uses a service called DHCP to assign IP addresses to all your devices, instructs them on how to look up websites and services on the internet using the Domain Name System (DNS), and provides a firewall to prevent intruders from accessing your devices.
Usually, other services are integrated into the router, such as Virtual Private Network (VPN) capabilities, Wi-Fi security, and Wi-Fi range extension using a Mesh Network.
Gateway:
Some devices are “all-in-one,” combining the router and the internet connection device (modem).
These devices are often sold by internet service providers. However, these technologies remain separate under the hood. You can always purchase the modem and router separately.
A Gateway device is a system used to connect and link different networks or devices across various networks. The Gateway translates and routes data between these different networks, which can have different protocols or technologies.
Sometimes the term Gateway is used to refer to a device that connects the Local Area Network (LAN) to the internet. For example, the router at home can be the Gateway that allows home devices to connect to the internet. This device routes data traffic between the home network and the public network (the internet).
The term Gateway is also used in many other technological and network contexts, such as internet security, where a Gateway device can perform firewall functions to protect the network, or in cloud computing, where a “Cloud Gateway” is known as a device that provides access to services and resources in the cloud.
In general, a Gateway device represents a point of communication or routing between different networks or systems and is an essential part of network and communication infrastructure in many scenarios.
What is the best solution for you?
It is recommended to purchase the modem and router recommended by your internet service provider. This way, in case of issues, technical support will be better equipped to assist you.
However, it is not advisable to buy a Gateway device. This is because modem technology evolves slowly, and it can take years before a significant technological change makes it worthwhile to transition to a faster and better standard.
The situation is different when it comes to the router (also known as a router). Wi-Fi technology, in particular, continually evolves with increased connection speeds and new security standards. To improve coverage and speed or to take advantage of the latest Wi-Fi technologies, you will need to update your router approximately every two years.
Additionally, internet service providers often lease equipment to you, which can cost you extra euros monthly. Therefore, it’s better to purchase a dedicated router if the device provided by your service provider does not meet your needs (such as Wi-Fi signal quality, for example).
Do I need both a router and a modem?
You should have a modem. However, you can do without a router if your internet service provider offers you a Gateway device. These devices combine a modem and a router in one package.
What is the best solution? Separate modem and router or a Gateway that combines them? Each of these solutions has its advantages. A Gateway is simpler in terms of setup, while if you decide to purchase a separate router, it will be easier to upgrade to the latest Wi-Fi standards.
Where should I place my modem and router? Usually, you should install the router near the modem so that you can easily connect them using an Ethernet cable.
You likely use Wi-Fi for most of your internet needs, so you should place it in the best possible location. Wi-Fi signals weaken or even fail due to obstacles like thick walls.
The best guidelines for placing your router are:
Place it near the center of your home or working space.
Put it on a desk, table, or shelf. The higher, the better. Do not place it on the floor.
Avoid placing it directly next to the wall, as this weakens the signal.
Do not place it near other devices that emit wireless frequencies, such as microwave ovens or cordless phones.
