A router is a networking device that forwards data packets between computer networks. It connects multiple networks together and directs traffic between them, allowing devices on different networks to communicate with each other. A router uses routing tables and protocols to determine the best path for data to travel. It also provides security features such as firewalls and virtual private networks (VPNs).
There are several types of routers, including:
Home routers: These are typically small, consumer-grade devices that connect a home network to the internet via a broadband connection.
Business routers: These are more powerful and feature-rich than home routers, and are designed for small to medium-sized businesses.
Enterprise routers: These are high-end devices used by large organizations to connect multiple networks and provide advanced features such as load balancing, virtual routing, and Quality of Service (QoS).
Wireless routers: These routers provide wireless connectivity to devices through Wi-Fi.
VPN routers: These routers support VPN connections and allows multiple users to connect to a remote network securely.
Edge routers: These routers are placed at the edge of a network and connect to other networks, such as the internet, to exchange traffic.
Core routers: These routers are placed in the core of a large network, and handle high-speed, high-volume traffic between different parts of the network.
What is Home Wireless Router?
A home wireless router is a type of router that connects a home network to the internet via a broadband connection (DSL or cable) and allows multiple devices to connect to the internet wirelessly using Wi-Fi. It typically includes a built-in Ethernet switch for wired connections, and often includes a built-in firewall for security. A wireless router is often used to create a home network, which can include computers, smartphones, tablets, gaming consoles, and other devices that can connect to the internet. Some of the popular brands for home wireless router includes, TP-Link, Asus, Netgear, D-Link, etc.
Different between ADSL and DSL router
ADSL (Asymmetric Digital Subscriber Line) and DSL (Digital Subscriber Line) are both types of technologies used to provide internet access over a telephone line. However, there are some key differences between them:
- ADSL is designed to deliver faster download speeds than upload speeds, while DSL is designed to deliver symmetric speeds, meaning that both upload and download speeds are the same.
- ADSL is generally used for residential internet access, while DSL can be used for both residential and business applications.
- An ADSL router is typically used in home networks, and is connected to a telephone jack to provide internet access. A DSL router is similar, but can be used in both home and business networks.
- Some DSL router may have additional features such as VPN, VLANs, Quality of Service, etc. It’s more advanced than the regular home router.
In short, both ADSL and DSL routers are used to provide internet access over a telephone line, but they have different capabilities and are used in different types of networks. An ADSL router is typically used in home networks, while a DSL router can be used in both home and business networks, and it has more advanced features.
2.4GHz Router
A 2.4GHz router is a type of wireless router that uses the 2.4GHz frequency band to transmit and receive data. This frequency band is one of the most widely used for wireless networking and is compatible with a wide range of devices, including smartphones, tablets, laptops, and gaming consoles.
The 2.4GHz band has a longer range than the 5GHz band, but it also experiences more interference from other devices that use the same frequency, such as microwaves, cordless phones, and other wireless networks.
This type of router is often used in homes, small offices, and other environments where the wireless coverage needs to reach a wide area. Many of the older wireless devices like smartphones, laptops and IoT devices only support 2.4GHz frequency, so 2.4GHz router is a good option for those who want to connect all those older devices to the internet.
It’s worth noting that most of the newer routers available in the market are Dual-band routers, which means they can operate on both 2.4GHz and 5GHz frequency band, giving more flexibility and better performance.
5ghz Router
A 5GHz router is a type of wireless router that uses the 5GHz frequency band to transmit and receive data. The 5GHz frequency band is less crowded than the 2.4GHz band and offers faster speeds, lower latency, and less interference.
This frequency band is suitable for devices that require high-bandwidth applications such as streaming HD video, online gaming, and large file downloads. It’s also better suited for environments with many wireless networks, such as apartment buildings or crowded neighborhoods, since there are more channels available in the 5GHz band than in the 2.4GHz band.
5GHz routers are also generally preferred over 2.4GHz routers for devices that support the 5GHz band, such as newer smartphones, laptops, and gaming consoles.
It’s worth noting that most of the newer routers available in the market are Dual-band routers, which means they can operate on both 2.4GHz and 5GHz frequency band, giving more flexibility and better performance.

Which is better?
Both 2.4GHz and 5GHz routers have their own advantages and disadvantages, and which one is better for you depends on your specific needs and the environment in which you will be using the router.
2.4GHz routers have a longer range than 5GHz routers, so they are better for environments where the wireless coverage needs to reach a wide area. They are also more compatible with older devices that only support the 2.4GHz band.
5GHz routers, on the other hand, offer faster speeds, lower latency, and less interference, making them ideal for devices that require high-bandwidth applications such as streaming HD video, online gaming, and large file downloads. They are also better suited for environments with many wireless networks, such as apartment buildings or crowded neighborhoods, since there are more channels available in the 5GHz band than in the 2.4GHz band.
Most of the newer routers available in the market are Dual-band routers, which means they can operate on both 2.4GHz and 5GHz frequency band, giving more flexibility and better performance. It’s a good choice for those who have both older and newer devices. In conclusion, the 5GHz band is generally preferred for high-bandwidth applications and environments with many wireless networks, while the 2.4GHz band is better for longer range and compatibility with older devices.
Channel
The 5GHz and 2.4GHz channels refer to the frequency bands that wireless devices, such as routers and smartphones, use to connect to the internet. The 5GHz channel offers faster speeds and less interference, while the 2.4GHz channel has a longer range but may experience more interference from other devices. Some devices may be able to connect to both bands, while others may be limited to one or the other.
There are a total of 14 channels that are available for use in the 2.4GHz band, and each channel is 20MHz wide. These channels are numbered 1 through 14.
In the 5GHz band, there are a total of 24 non-overlapping channels available for use, with each channel being 20, 40, 80 or 160 MHz wide. These channels are numbered 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 149, 153, 157, 161, 165.
Please note that availability and usage of channels may vary depending on country and region, as well as specific restrictions that may be in place by the regulatory authorities.
