And this uninterrupted connectivity with the internet is made successful by two devices, a router and an access point. They become useful for different situations and enable people to connect with a network wirelessly.

Key Takeaways

  1. Routers manage and direct network traffic between different networks, such as connecting a local network to the Internet.
  2. Access points extend the wireless coverage of a network, allowing devices to connect to the network wirelessly.
  3. Both routers and access points play essential roles in creating a functional and efficient network, but they serve different purposes.

Router vs Access Points

A router is a device that connects multiple devices to a network and allows them to communicate with each other and with devices on other networks, such as the Internet. An access point is a device that provides wireless connectivity to devices on a network. It extends the range of a network.

A router is known to be a networking device. It gets used in forwarding data packets between different computer networks. Data packets can be anything sent on the internet.

It is a set of data. The router is responsible for transmitting this data from one network to its destination.

The access point is a hardware device that gets used in computer networking. To fulfil its functions, it gets connected to a router through the use of a wire.

A strong Ethernet connection helps to transmit the data. With one wired connection, an access point can supply data to multiple devices without any wired connectivity.

Parameters of ComparisonRouterAccess Points
Obtaining wireless hardware A router does not have any such hardware. Access points have it and use it to transfer data.
AlgorithmsRouters have tricky algorithms. Access points do not possess any algorithms.
Data packetsRouters route data packets to their destination as a part of their function.Access points are not able to do so.
FunctionA router connects the internet with the access point.Access points make Wi-Fi devices connect to it.
PurposeA router sets up a local area network or LAN.Access points let other devices connect to the LAN.

What is Router?

A router is a networking device responsible for routing data across a local area network. It is a 3-layer device as it follows the OSI reference model.

To work, a router uses a table which is known as a routing table. This table consists of IP, and by this IP, the router is able to reach another certain destination IP address.

To work efficiently, an access point needs a router to get connected to wireless devices to the internet. The main objective of a router can be divided into two parts.

One is it can connect multiple computers, smartphones, and other devices in order to maintain a local area network or LAN. Secondly, the router is responsible for providing Internet access to its connected devices.

To provide and transmit the Internet, the router needs to get connected to an Internet service provider through an Ethernet cable. A router might retain a firewall and VPN handling as its security methods.

Ensuring the security of a LAN is very important, and a router can ensure that to some extent. A data packet is a set of data that is meant to reach its destination, and the router helps to accomplish this mission.

In this process, routers use the information available in their routing table.

What are Access Points?

An access point is a device that is responsible for connecting wireless devices to a wired network. Access points are inevitable devices in Wi-Fi technology.

Devices that are connected to the access point will gain an internet connection through a router. And an access point will be connected to a router.

A high-speed Ethernet cable establishes this connection and is responsible for transmitting the signal from wired to wireless.

This way, all the devices connected to the point are interconnected. However, technology has come a long way, and modern wireless routers and access points can get integrated into a single device.

The access point will distribute data by creating a Wi-Fi hotspot. Any device in the home can connect to an access point and access the internet.

A network can bear a limited number of users to connect to it. However, this limit can get extended with the use of access points. It expands the wireless coverage and gives an opening to more users to get joined in the network.

Main Differences Between Router and Access Points

  1. The router is responsible for connecting outside networks with the access point. It connects the router to the internet, whereas access points connect with wifi devices which will use that internet.
  2. If a router is a hub, then the access point is a sub-hub. A router is meant to create a LAN, and access points give access to multiple devices in the created network.
  3. Routers have complicated algorithms and routing tables to follow, but access points do not have any such complicated elements.
  4. Routers do not have any wireless hardware, but access points do have such hardware.
  5. The router connects the internet with the access point, and the access point connects it to other multiple devices.
