How to Connect Two Routers Without a Switch: Methods and Considerations

Connecting two routers without a switch might seem like a common task, yet it requires careful consideration of the network setup and potential limitations. This guide will explore different methods to achieve this connection and explain the considerations and limitations for each approach.

1. Connecting Routers Directly Using LAN and WAN Ports

The most straightforward method for connecting two routers without a switch involves utilizing the LAN and WAN ports. Here’s how you can do it:

Connect the main router Router 1 to your ISP modem via its WAN port. Connect the WAN port of Router 2 to a regular LAN port on Router 1. Both routers should now be functional, and any port on either router can be connected to the Internet. However, you cannot directly connect any port on Router 1 to a computer connected to Router 2 unless you reconfigure the firewall settings on Router 2.

This setup is useful in certain circumstances but might not be the most efficient way to increase your network's port capacity. Moreover, it might introduce Network Address Translation (NAT) issues and potential interference.

2. Configuring Wireless Repeater Mode on Routers

For a more straightforward wireless network extension, wireless repeater mode can be utilized. This mode essentially extends the network range by using a portion of your primary router's wireless signals. Here’s how to implement it:

Check if your router: Ensure your Linksys Smart Wi-Fi Router supports this mode. Check this by logging in to the router's web-based setup page and navigating to Connectivity > Internet Settings. Select the frequency band: Decide which frequency band you will use for repeating the signal. Configure the settings: In Connectivity > Internet Settings, you can choose to use the 2.4 GHz frequency band if your main router is single-band. If your main router is dual-band, you can edit the wireless settings for both frequency bands in the Wireless widget. Do not use the WAN port: Remember to avoid using the WAN port when configuring router 2 as a repeater. Log in via the IP address: Access the router’s web-based setup page using the internal IP address, not the WAN IP address. Supported encryption methods: Ensure you use compatible encryption methods such as WPA-Personal, WPA2-Personal, or WPA-Mixed-Personal.

Wireless repeater mode is particularly useful for extending network coverage without the need for additional hardware, making it a practical option for many users.

3. Alternative Solutions: Using a Small Switch

If you need to connect multiple devices and maximize your network's port capacity, using a switch is the ideal solution. While it might not be as cost-effective as some of the previously mentioned methods, a small switch can drastically improve your network setup and functionality. Here’s a quick comparison:

Small switch vs. configuring routers: If you need more than a couple of additional ports, a small switch would be more efficient and reliable. Cost-effective option: Consider a small switch that costs around $35-$40, which would provide better network performance and fewer potential issues than configuring multiple routers.

While it may not be the most straightforward DIY solution, investing in a small switch ensures a stable and expandable network infrastructure, making it a worthwhile addition to any network setup.

Conclusion

The method you choose to connect two routers without a switch depends on your specific needs and the complexity you are willing to handle. If you are looking for a simple cost-effective solution, configuring a router in Wireless Repeater mode is a great option. However, if you require more ports and stability, purchasing a small switch might be the better choice for your network setup.
