How to connect Wi-Fi extender to Spectrum router

Preparation of the network

The first thing you start by doing is preparing the network for connection. Preparation of the network involves setting up the router or Spectrum modem router. Be sure to check for compatibility of the model before getting to the setup process.

Setting a Spectrum network

1. Connect the cable

Start by connecting the coax cable to the internet outlet and then power the Spectrum modem router. Let the modem startup as some do not have routers. Spectrum should automatically connect with the modem.

At times the process may fail. You will need to disconnect the devices and then make a new connection.  Check on the IN and OUT ports so that they connect correctly.

2. Connect the modem to the router

Once the modem is ready and functioning, the next step is to connect it and the router. Using the Ethernet cable and ports, you will connect the yellow port of the router to the port of the modem. 

Plug the power port of the router into the power source and switch it on. If there is a small challenge with the connection, you can consider disconnecting and redoing the connection. 

The way to know if the connection is behaving as you expect is by checking on the lights.  If you don’t see the green lights, you can switch the device off then on.

3. Set up the device

The setup process is simple as it offers straightforward procedures. You can choose to use a mobile app or any setup device. Using this device, you will choose a unique SSID and password that you can find on the back of the router.

Once you have logged in, you will have a chance to make various changes, such as choosing a different username and different password. Once the router is set, you can begin to connect your other devices, including a Wi-Fi extender, to increase the range.

When activating the connection, you will go to for both the router and the modem. Note that you will not use the connection if it is not active.

4. Connecting the Wi-Fi extender

You will, first of all, remove the device from the box and go through its manual. Ensure that it has all the things you need to install it.

If it has antennas, you can raise them at vertical positions to cover the stipulated range.

2. Install the Wi-Fi extender

The process of installation involves using the apps or the router to get the best position. After locating the optimal location, you will mark the route that the cable will follow. Most extenders use cables to connect to the router.

When preparing the router, you need to ensure that the path does not cross with the path of the electric cable.

The placement of the extender from the router should stand between 15 and 25 feet to ensure that there is a stable connection. When connected, check the lights to assess the success of the connection.

3. Use the WPS button

You now need to locate the WPS button and make use of it for your settings. The button is either on the side of the front of the router and the Wi-Fi extender. It is also clearly labeled on most devices.

After you locate the button, you locate the EPS button and press it too. When the lights are green, the connection process is successful, and the two devices have paired.

You can do this process before you locate the optimal location to ensure that the device is functional. The WPS button when available is one of the easy ways to connect a Wi-Fi extender to a Spectrum router.

4. Configure the extender

Once you finish the installation and setup process, you will do the configuration process. This is the process that prepares the extender for functionality.

If you have to set up the passwords and the SSID codes, you will use web interfaces or mobile apps. Make sure that the password and keys are similar to the existing connection.

Once the passwords are set, you will get the WIFi extender set up for placement at the right place. However, you will need to test the connection before placing the WiFi extender at your optimal place.

Test for the connection

Once you complete all the previous connections successfully, you will then test the connection.

You can choose to use an analyzer app to see how effective the connection is. The analyzer app will guide you on the connection stability, strength of the signal, and WIFi speeds.

Choosing to use your devices such as a laptop or smartphone to see how they behave. Connecting the Wi-Fi extender to the spectrum router is now a successful task.

When the Wi-Fi extender has an enhanced speed, all your connected devices will enjoy high and reliable speeds. Dual and triband are better devices when it comes to retaining the speeds of the router.

Range coverage

The primary purpose of a Wi-Fi extender is to improve the range of the connection. When you have a device that covers a small range, it will do small extension work.

However, if the WiFi extender covers an extended range, you will be sure that you can freely roam without hassle.

When buying the device, it is essential to ensure that you know the area where you intend to improve the connection. Getting a device that covers the same range or more from this point becomes a simple task. If you have a house with multiple floors, you will need one with a broader range.

Technological improvements

There are various technological features that each device comes with. These features enable your WiFi extender to give you the latest internet protection, speed, connection to multiple devices, and excellent range.

Some of these features include beamforming and the MU-MIMO technology. Fastlane technology is also essential as it helps the device serve the speeds and signal stability without a hassle.

Triband and dual-band devices also seem to perform better because of the simultaneous streaming. Spot finder technology is another beautiful feature that makes the process of identifying the optimal point more convenient.

Ease of setup

The process of setting up the Wi-Fi extender, which is what the article is addressing, should be simple and convenient. You should not have a challenge in setting up the WiFi extender or troubleshooting it.

A good Wi-Fi extender should offer a straightforward process of connecting the device to the router. Configuration of the extender settings should also be a straightforward task that you should follow without a technician.

Setting the device up will need a mobile app or a web interface. The app should be simple to use, and the commands simple to click and follow.

A good extender can have different methods of setting up so that you follow the one you will quickly work with.

Quality of the performance

A good extender should maintain reliable performance. The signal should comfortably cover the stipulated range without any struggle.

If you have wired and wireless devices, each should have a chance to enjoy the connection.

Devices operating from the farthest end of the range should also enjoy a fast and reliable connection. Device prioritization responsible for making each device consume the right amount of internet as per its needs should also conveniently work.


Why is my WiFi extender not connecting to the internet?

There are many reasons why your WiFi extender may not be working properly and you need to troubleshoot them one by one. The first thing you should do when your WiFi extender is not connecting to the internet is to check if it has power by plugging it into an electrical outlet and then look at its lights. If there’s no light on, make sure that the power cord is plugged in properly and try resetting the device using a paper clip or pin. You can also check if there’s any physical damage like tears or dents on the Ethernet cable which connects your computer/device to your router. After checking these things, restart both devices (router & WiFi range extender) one after another so they sync up again as they may have been disconnected while troubleshooting them separately earlier on. In addition, you can check for outdated WiFi extender’s firmware, faulty hardware, or even signal interference by other networks or devices. Finally, you should check if you have placed the WiFi extender in a dead zone instead of midway between the router and the dead zone.

How can I use my old router as a Wi-Fi extender?
