Ethernet Switch vs. Router: How to Choose (2024)

FAQs

Should I connect Ethernet to router or switch? ›

The ethernet switch works well for connecting multiple devices in a limited area, and the router will help when someone needs to send or receive information from a source within a WAN. Knowing what technology you need to ensure that your network has a correct setup is essential.

In practice, what this means is that routers are necessary for an Internet connection, while switches are only used for interconnecting devices. Homes and small offices need routers for Internet access, but most do not need a network switch, unless they require a large amount of Ethernet* ports.

While a network switch can connect multiple devices and networks to expand the LAN, a router will allow you to share a single IP address among multiple network devices. In simpler terms, the Ethernet switch creates networks and the router allows for connections between networks.

From the previous paragraph, we can conclude the matter of slower speeds that Ethernet switches can reduce speeds if they are from an old generation or from a poor feature packing brand. Most users who have been using 10-100 Mbit outdated switches may have experience network slowdowns.

For instance, in environments with MAN or WAN types of networks, a router works faster than a network switch. Network switch: In contrast, network switches are only used for LAN environments. In LANs, a network switch is faster.

If you wish to connect a large number of devices to a wired Internet connection, you can use an outdated router as a network switch. The major motivation for doing this is to double the number of Ethernet connections that are accessible for a wired connection, especially if router latency is an issue.

In the case of various network environments (like WAN/MAN), a router will work much faster than the switches. A switch can work comparatively faster than a router when deployed in a LAN environment. The operations of a router revolve around the IP addresses. In the case of switches, they work with the MAC addresses.

Commonly, in a home setup, you will see the modem installed first, followed by a router and then the Ethernet switch. Here is the key operational principle: the modem passes the public IP address to the router, and in turn the said router assigns private IP addresses to the devices connected to it.

A switch's hardware can do the routing, at wire speed. And offloading the router allows it to better handle its WAN connectivity and firewall functions, improving overall network performance.

For these reasons, Ethernet switching is essential to enterprise networking, as having multiple ports enables faster connectivity and smoother access across many devices simultaneously.

What is the difference between 100 and 1000 Ethernet switch? ›

These numbers indicate the maximum rate that a port on a switch can transfer data. 100Mbps is often referred to as “Fast Ethernet”, 1000Mbps as “Gigabit Ethernet” and 10000Mbps as “10Ge” or 10 Gigabit Ethernet. The number of channels that can traverse one link in a network is proportional to the link speed.

Both Routers and Switches are network connecting devices. Routers work at the network layer and are responsible to find the shortest path for a packet across the network, whereas Switches connect various devices in a network. Routers connect devices across multiple networks.

A router can also handle different types of traffic, such as IP, TCP, UDP, and ICMP, while a switch can only handle Ethernet traffic. A router can also make decisions based on the network layer (layer 3) or higher, while a switch can only make decisions based on the data link layer (layer 2) or lower.

But if for an office then the above is the correct answer. Assuming each of the routers will be connected to a different circuit and if the routers are configured as transparent bridge ( I don't see any other reason to do this), yes you can connect both to a network switch, provided this is layer 2 switch.

Make sure you plug the Ethernet cable from the modem into the correct Ethernet port on your router. Be sure that you properly secure the wireless gateway to the internet connection entering your home.

Switches are smarter and more efficient hardware devices than network hubs because of their ability to record information and learn MAC addresses.

Plugging a computer or laptop directly into a modem is a bad idea. This is a major security risk because it bypasses security configurations that a router (or, modem/router combination) have set up by default.

Ethernet connections can support up to 10 Gbps, while the current maximum speeds with Wi-Fi are limited to 2.4 Gbps.
