How to use a router as a network switch

A router is a network device that allows you to connect multiple devices to a network. However, there are situations where you need more Ethernet ports to connect devices and the router does not have enough of them. In this case, you can use a router as a network switch.

The switch function of the router allows you to create a local network (LAN) within your home or office. This means that all devices connected to the LAN can communicate with each other without having to go through the Internet.

How does the switch function of the router work?

The switch function of the router allows you to create multiple Ethernet ports to connect devices. When you activate the switch function, the router becomes a bridge between different Ethernet ports, allowing data to pass from one port to another.

For example, if you have two computers connected to the router via two Ethernet ports, these computers will be able to communicate with each other thanks to the switch function of the router. Data traffic will be routed directly between the two Ethernet ports without having to go through the Internet.

  • The first computer sends data to the Ethernet port it is connected to;
  • The router receives data from the first Ethernet port;
  • The router routes data to the second Ethernet port;
  • The second computer receives data from the second Ethernet port.

The switch function of the router allows you to create a faster and more stable local network compared to Wi-Fi connection. In addition, Ethernet connection is less prone to interference and signal problems compared to Wi-Fi connection.

In the next section, we will see how to configure a router for use as a network switch.

Configuring the router as a network switch

To configure your router as a network switch, follow these simple steps:

Step 1: Disable DHCP function

The first thing to do is to disable the DHCP function on your router. This function assigns IP addresses to devices connected to the network and may cause conflicts if there are other devices in your network that perform this same function. To disable the DHCP function, access the administration panel of your router and look for the "DHCP" option. Disable this option and save the changes.

Step 2: Connect the router to the switch

Now you need to connect your router to the switch using an Ethernet cable. Insert one end of the cable into the LAN output of the router and the other end into one of the ports of the switch.

Step 3: Configure the IP address of the switch

At this point, you need to configure the IP address of the switch. Access again the administration panel of your router and look for "IP Address Assignment" option. Select "Manual Assignment" and enter an IP address for the switch. Make sure that the IP address is different from that of the router but part of the same subnet.

Step 4: Connect devices to the network

Now you can connect your devices to the network using the switch ports. Make sure to manually configure the IP address, subnet mask, and default gateway for each device.

By following these simple steps, you have successfully configured your router as a network switch. Now all devices on your network can communicate with each other seamlessly.

Connecting Devices to the Router-Switch

Once you have set up your router as a network switch, you can start connecting your devices. Here's how:

Step 1: Turn off all devices

Before you begin connecting your devices to the router-switch, make sure they are all turned off. This way, you'll avoid any potential damage to the devices or the router.

Step 2: Connect an Ethernet cable from the device to the router-switch

Take an Ethernet cable and connect one end to the Ethernet port of the device you want to connect (e.g. a computer). Then, connect the other end of the cable to the Ethernet port on the router-switch that you want to connect the device to.

Step 3: Turn on the device and check the connection

After connecting your device to the router-switch, turn it on and check if it is properly connected to the network. If you're connecting a computer, go to "Network Settings" and check if the computer detects an internet connection.

Step 4: Repeat for other devices

Repeat these steps for every other device you want to connect to the router-switch. Make sure to use a separate Ethernet cable for each device.

  • Example:
  • If you want to connect another computer to the router-switch, take another Ethernet cable and connect one end to the Ethernet port of the second computer. Then, connect the other end of the cable to another free Ethernet port on the router-switch.

By following these steps, you can easily connect your devices to your router-switch and create an efficient home or business network.

Checking Connection and Troubleshooting

After setting up the router as a network switch, you may encounter some connection issues. Here are some tips to troubleshoot:

1. Check physical connection

  • Make sure Ethernet cables are properly connected to the LAN ports on the router and the device you want to connect.
  • Check if cables are damaged or bent. If necessary, replace them with new cables.

2. Check network settings

  • Verify your device's IP settings. Make sure it is set to "Obtain an IP address automatically" or manually input the correct IP address.
  • Also check subnet mask and default gateway settings on your device.

3. Restart the router and device

  • Restart both the router and the device you want to connect to.
  • Turn off both devices for a few seconds and turn them back on.

4. Update the router firmware

  • If you are still experiencing connection problems, you may need to update the router firmware.
  • Find your router model on the manufacturer's website and download the latest available firmware. Follow the instructions for updating the firmware.

By following these tips, you should be able to solve most connection issues after setting up the router as a network switch.

Advantages of using a router as a network switch

Using a router as a network switch can offer numerous advantages, including:

  • Saving money: A router can be purchased at a lower price compared to a dedicated network switch. Additionally, by using the router as a switch, there is no need to purchase additional devices for connecting computers to the network.
  • Traffic management: Routers are designed to handle network traffic efficiently and intelligently. This means they can help improve network performance by avoiding congestion or slowdowns.
  • Security: Routers offer greater security compared to switches because they include features such as firewalls and Network Address Translation (NAT). These tools can protect computers on the network from potential external threats.
  • Flexibility: By using a router as a switch, the network can be configured more flexibly. For example, it is possible to assign static IP addresses to computers on the network or set specific rules for traffic management.
  • Wireless coverage: Many routers also include Wi-Fi capabilities, allowing mobile devices to connect to the network without additional cables.

In addition, by using a router as a network switch, it is possible to take advantage of the advanced features offered by modern routers, such as Quality of Service (QoS), which allows prioritization of network traffic based on user needs.

In summary, using a router as a network switch can be an affordable and flexible solution for improving the performance of your home or business network.

Conclusion

As we have seen, using a router as a network switch can bring numerous advantages. Thanks to its ability to handle traffic efficiently and intelligently, routers can help improve network performance and ensure greater security for connected computers. Additionally, thanks to the advanced features offered by modern routers, it is possible to configure the network more flexibly and adapt it to specific needs. So if you are looking for an affordable and flexible solution for your home or business network, consider using your router as a network switch.
