Can i connect multiple switches to my router

In the computer networking world, the three most ubiquitous pieces of equipment are Ethernet switch, router and modem. These are applied everywhere from data center to network connections in your own home. However, despite the importance of these three pieces of equipment, some people are oblivious or confused to their internal functions and connection mode. So in this article, we will attempt to explain the difference between each piece of equipment and introduce the common way to connect Ethernet switch, router and modem.

From a physical perspective, a modem, router and Ethernet switch look very similar. Nevertheless, there are key differences between them internally and functionally with relevant purposes on a network. An Ethernet switch is commonly referred to as a multi-port network bridge that processes and routes data on a data link layer layer 2 and sometimes network layer layer 3 of the OSI model.

It has the capability to learn and distinguish between specific addresses by accessing them from a CAM table. It takes information provided by the modem or ONT and routes it to the various devices that are connected.

Router uses protocols such as ICMP Internet Control Message Protocol to communicate with each other and configures the best route between any two hosts. The main purpose of a modem, when used in a home networking environment, is to establish a connection between your home network and ISP.

There are a handful of ways to set up a shareable home network connection, but the safest and most reliable way is to use a router and switch in combination. Once the switch is behind a router which in most cases uses NATall devices connected to either the switch or the router can access the internet simultaneously. Placing the router between modem and Ethernet switch creates an extra layer of protection from threats on the Internet.

Step 1 : Unplug the power supplies of cable modem, switch and wireless router. Unplug any Ethernet cables that are plugged into any of them. Step2 : Connect telephone wire with modem, and then connect an Ethernet cable to the Ethernet port on the back of the cable modem.

Step4 : Connect another Ethernet cable to numbered Ethernet port on the switch and plug the other end into the LAN port on the wireless router. Step5 : Plug the power supplies of the modem, Ethernet switch and router in. After two minutes, the network and Internet connection is ready to go. As you read this, you may be clear about the knowledge of Ethernet switch, router and modem and the proper way to connect them in a network. For suitable Ethernet switch and gigabit switch of good quality, FS would be your great choice.

Toggle navigation Fiber Optic Network Products.While most home computer networks use only one router, adding a second router makes sense in a few situations. A second router upgrades a wired network to support a larger number of wireless devices.

An additional router extends the wireless range of a home network to reach dead spots and to network a wired device that's too far away from the original router. In addition, a second router creates a separate subnetwork within a home to stream video among some devices without slowing down connections to others. Making it all work requires just a few steps.

When you set up a new router, place it near a Windows PC or another computer that can be used for the initial configuration. Both wired and wireless routers are best configured from a computer connected to the router with an Ethernet network cable.

You can move the router to its permanent location later. A second router that doesn't have wireless capability must be connected to the first router with an Ethernet cable. Plug one end of the cable into the new router's uplink port sometimes labeled WAN or Internet.

Plug the other end into any free port on the first router other than its uplink port. Home wireless routers can be connected using Ethernet cable in the same way as wired routers are connected. Connecting two home routers over wireless is also possible, but in most configurations, the second router can only function as a wireless access point instead of a router.

The second router must be set up in client mode to utilize its full routing functionality, a mode that many home routers don't support. Consult the specific router model documentation to determine whether it supports client mode and, if so, how to configure it.

If both the existing and second routers are wireless, their Wi-Fi signals can interfere with each other, causing dropped connections and unpredictable network slowdowns. Each wireless router uses specific Wi-Fi frequency ranges called channelsand signal interference occurs when two wireless routers in the same house use the same or overlapping channels. Wireless routers use different Wi-Fi channels by default depending on the model, but these settings can be changed in the router console.

To avoid signal interference between two routers in a home, set the first router to use channel 1 or 6 and the second to use channel Home network routers also use a default IP address setting depending on the model.

The default IP settings of a second router do not require any change unless it is to be configured as a network switch or access point. The above procedures enable an additional router to support a subnetwork within a home network. This approach maintains an extra level of control over specific devices, such as placing extra restrictions on their internet access. Alternatively, a second router can be configured as an Ethernet network switch or—if wireless—an access point.

This arrangements lets devices connect to the second router as usual but does not create a subnetwork. For households that want to extend basic internet access plus enable file-and-printer sharing to additional computers, a no-subnetwork setup is sufficient, but it requires a different configuration procedure than given above.

To set up a new router as a network switch, plug an Ethernet cable into any free port of the second router other than the uplink port and connect it to any port of the first router other than the uplink port. To set up a new wireless router as an access point, configure the device for either bridge or repeater mode linked to the first router.Deals Amazon deals Bargain threads Classified adverts.

Is it possible to have 2 switches connected to 1 router? Thread starter s0hail Start date Jan 17, Im pretty sure i can but before i go and buy a couple of switches i was wondering is it possible for me to have my router with 2 computers hard wired in and switches coming of the other two ports?

Andy Distinguished Member. It should be no problem. I have such a setup. Kristian Member. As Andy says, that will work fine. Just don't create a loop when connecting it all up. Dialatech Banned. Yeah that would be fine but don't go crazy. The more switches you add to the setup more your internet connection will suffer. As others have said, should be no problems.

I have the same configuration two switches hanging off the router. Dialatech said:. Last edited: Jan 17, Kristian said:. Basically networks switch are running data links under the layer 2 in the OSI model. Switches are dump, there basically using the connection to all ports not just the ones that are active.

An umanaged switch just passes data between the appropriate ports without asecond thought. Were routers are more intelligent and now just ports are active and which ones are not. No im not getting confused with Layer 2 Swicthes and Layer 1 Hubs at all. Unmanaged switches will just send the connection to the ports that are connected to by MAC Address,That is Very true but if Sohail uses say switches by time the connection gets to Switch 3 or Switch 4 the connection would have suffered.

Thats what im saying. Sohail will be fine but im just saying the connection will suffer when it gets to switch 3.In the big data era, gigabit Ethernet switch with high capacity has gradually penetrated from big enterprises, SMB to small offices and homes. Therefore the Ethernet topology requires for a comprehensive integration of various devices like firewall, servers, routers and multiple Ethernet switches. How to connect multiple managed switches together?

Can I simply connect network switch one by one?

How to Connect Two Routers on a Home Network

Does daisy-chaining switch make sense? Or should I stack switch with stackable switch to set up a switch stack? Switch cascade is a traditional way to connect multiple Ethernet switches, which comes with various methods and network topology under different requirements. Among them daisy chain topology and star topology are two common ways. Daisy chain is a layout form to connect multiple Ethernet switches together in sequence or in a ring. A simple linear topology displays as A-B-C, in which you just daisy chain each network switch top to bottom.

For no more than 3 Ethernet switches, a linear topology of daisy chaining is okay since there is no loop. However, it owns drawbacks in switch failure due to lacking redundancy. Once one network switch fails, the others will also be dragged in. A simple ring topology is A-B-C-A, which can provide redundancy in link failure. However, simultaneously a loop creates when you finally daisy chain switch C back to A.

Thus even only daisy chaining 3 Ethernet switches, an inevitable loop can be a fatal weakness. Simply put, daisy chaining switch is error-proof and easily causes unnecessary low performance issues. Besides loop, a bottleneck creates in the chain and speed will slow down when traffic passing through the second Ethernet switch since the link is heavily utilized.

So daisy chaining switch is not recommended if scheme is optional. For simple home use or low demand networks, daisy chaining switches can make sense. But make sure your network switch support STP to deal with the loop issue.

Figure 1: An illustration of daisy chain topology vs star topology for connecting multiple Ethernet switches. Compared to daisy chain topology, a physical star topology by deploying a powerful core switch to connect multiple access switches with uplinks is an optimal solution.

Or connecting a powerful gigabit Ethernet switch to each edge switches. In this scenario no loop occurs and all access switch is much closer to the central switch data center. For redundancy concern, you can also double or triple uplink each access switch to the core switch. Figure 2: Deploying a powerful gigabit Ethernet switch ST4S as core switch to connect edge switches, which forms a simple star topology. Daisy chaining switch can be a solution when Ethernet switch quantity is small and separate placement is required in low demanding applications.

How about an optimized way to connect multiple switches? Here comes stackable switch. Stackable switch deploys advanced stacking technology to achieve switch stacking, leaving out performance issues of clumsy daisy chaining topology like loops and bottlenecks. To stack switch with managed stackable Ethernet switch can set up a switch stack, which works as a unified system with one console port for control to enhance network scalability and simplify network management.

The port density and performance of switch stack can equal to expensive rack mount switch. Both Ethernet switch supports up to 4 24 port switches stacked together, providing 96 1GbE port density and switching a total capacity of up to Gbps. Also with single and dual power supply available, this 24 port gigabit managed switch offers redundancy in emergent power outage.Extending the WiFi network is something that most people seem to want nowadays.

This is where double routers are coming into play. People often start by purchasing a new router to extend their WiFi.

The mistake they do afterward is to throw the old router away. Why not use it to further extend your network? Connecting the second router to the first can greatly increase your network coverage. But there are also other benefits of having two routers except for better WiFi.

Most routers have USB which you can use on multiple points in the house for mass-storage, network printing or whatever you want. But the best of all is that it is much easier than you might think to add a 2nd router to your network. Connecting two routers might not be the first option that you think of when you think about extending your network. Having a second router means that you can get more ethernet ports, for example.

I have two routers at home and this was the main reason why I wanted to set up the second router in the other room.

Is it possible to have 2 switches connected to 1 router?

But it was also because I needed USB ports over there. But we also need to talk about the WiFi extension, which is the reason you are looking for a solution to this, I guess. However, since I decided to go with a 2nd router, I now have an apartment where every single part of it has a wireless network. The balcony has full WiFi access as well as the sofa in the living room, which is on the other side of the apartment. So, if you have an old router at home and want to get a better WiFi network in other parts of your house or apartment, I highly recommend that you dig up the old router that you have, instead of running to the store to purchase new hardware.

Down below, I have written a detailed guide on how to set up, and you can easily follow along. Before we get started with how to use two routers and yet, have just one network, we first need to understand how the second router should be set up.

Nowadays, you can purchase something called access points, or WAP, wireless access point. This is a product that is doing nothing other than to extend your WiFi connection. A big difference between a router and an access point is that a router is doing so much more than an access point. A router can also do stuff like port forwarding and other types of networking stuff.

If an access point gets a DHCP-request, it will forward that request to the router. What we need to do, is to make one of the routers more like an access point. There are two ways to do this. If you have a router that is just a few years old, there is a high chance that the router has something called AP Mode.

When a router is set to AP Mode, all things that are different between a router and an access point is turned off automatically. However, if you do not have this setting, you will need to turn off these things manually.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

It only takes a minute to sign up. They are looking to add another EdgeSwitch and connect both switches together for a single broadcast domain. However, is it possible to connect both switches together, and then connect both switches to the router? The idea is that internet traffic will go directly from either switch to the router, but LAN traffic can go directly in-between switches. Possible to connect each switch to the router and to each other?

Yes, but it isn't as simple as just connecting them. To get the operation you describe "internet traffic will go directly from either switch to the router, but LAN traffic can go directly in-between switches"? No, not without complicating the configuration of end devices and making maintaining the network exponentially more difficult.

The interfaces on the router will either be L3 interfaces which would require separate IP addresses per interface or L2 bridged interfaces which is not recommended - see below. With L3 interfaces, each interface would have a different IP address. The devices connected to the network will only have one of them configured as a default gateway and all internet traffic would flow through that one L3 interface.

The only way to get it to work as you describe is to do something crazy like manually configure GW1 on devices connected to SW1 and GW2 to devices connected to SW2.

With L2 interfaces, spanning-tree should work to provide a loop free environment L2 loops are bad. This means that all the traffic will either flow from switch to switch then out one router interface or all traffic between switches will flow through the router. Personally, I would connect both switches to the router and to each other, but simply for redundancy.

Each L3 interface has it's own IP address and then "float" an IP between them, which would be the gateway.


If you have a problem with one link to the router one of the switches dies, cable gets disconnected, etcthen internet traffic will still be able to flow out the other L3 interface.

Finally for the note on bridging; bridging is discouraged by the vendor at least for some Edgerouter platforms :. It is generally discouraged to enable bridging because traffic which is bridged is not hardware-offloaded, and will cause a decrease in performance. It is highly advised to use a dedicated switch connected to one of the LAN interfaces to allow for multiple ports of connectivity to the LAN rather than bridging.

The easiest solution is to connect the new switch to the existing one. If you're not looking for redundancy or need to remove a bottleneck from the network, that's all there is to it. Most often in small networks, a single gigabit link can easily carry all the traffic there is, whether it's between the switches or with the outside world through the router. However, if you're looking for redundancy or performance increase, you'll need to explain your situation and your goal in a more detailed way.

If you set up all clients manually, you can configure them in that way, but using DHCP you'd need to figure out a way to pass them different default gateways. The usual way would be to use two edgerouter sockets as a switch and connect the two switches directly. If that's not practical for wiring reasons, then you chain the switches together as has been already suggested.

Connecting two switches to a router

I'm guessing there are no significant performance considerations. Routers route between network, so each router interface belongs to a different network.

Since you cannot connect both switches directly to the same router interface, you would be connecting them to two different networks. Also, switches use spanning-tree in order to create a single, loop-free path on the layer-2 LAN. In order to do this, all switch traffic is sent to the elected root switch. A switch has no idea which packets are destined for the Internet because all layer-2 traffic is local. Switches know nothing about your layer-3 addressing.

You can connect the second switch to the first one and extend your network easily. However, this network which is called "daisy chain network" is not recommended since your network would be more vulnerable. If anything happens to the first switch, the rest of the network would be affected.Menu Menu. Search Everywhere Threads This forum This thread. Search titles only.
