How to Expand WiFi Coverage with a Second Router

Is it possible to connect a second WiFi router to the first without using any cables or wires? The answer can vary, but we'll explore the steps and conditions needed to achieve this goal.

Conditions for Connecting to a Second Router

For a second router to be connected to the first without any physical connection, the first router must have the capability of a wireless network repeater. Without this feature, the answer is often no for normal WiFi routers.

Mixing Interfaces: Possibilities and Limitations

If one or both routers have a different type of interface in common such as a T1 DSU/CSU serial interfaces, ISDN BRI, fiber, or even other non-Ethernet interfaces, it might be possible to connect them. However, this is generally not the case for most Small Office/Home Office (SOHO) routers that typically only have Ethernet or WiFi.

Mesh Networks: Seamless Coverage

A mesh network is another option to achieve the desired seamless WiFi coverage. In a typical mesh network setup, the main router is connected to the service provider's modem, and satellite mesh nodes are scattered throughout the premises on the same SSID, creating one contiguous network. These nodes are usually connected by Ethernet cables or WiFi bridges. However, for a fully wireless setup, both methods may require additional configuration.

Separate Local Networks with a Second Router

It is possible to connect a second router to the first, but it will create a separate local network. This can be utilized to segment your network, for instance, to keep your kids away from your home office. Devices connected to the first router can't connect to devices on the second network, meaning kids won't be able to access your home office printer, etc.

Steps to Turn a Second Router into a Range Extender

To set up your second router as a range extender, follow these steps:

Ensure that your second router supports range extender mode.

Connect the power adapter to the router and turn it on. Optionally, connect a computer to the router via an Ethernet cable or wirelessly by using the SSID and password printed on the bottom label of the router.

Open a web browser and enter 192.168.1.1 in the address bar. Use admin for both username and password, and then click Login.

After logging in, select Repeater mode and follow the Quick Setup to complete the configuration. Click Survey to choose your host network and fill in its wireless password.

Relocate the router to an optimal position between your host router and the Wi-Fi dead zone, ensuring it is within the range of your existing host network.

Enjoy the extended network, which will share the same SSID and password as your host network.

Conclusion

While fully wireless connection of a second router to the first can be challenging, using a range extender mode or setting up a mesh network can effectively expand your WiFi coverage and optimize your network performance. Choose the method that best suits your needs and network requirements.
