Getting ready for installation

Tu módem llegará por correo a más tardar en la fecha para la que se programó el inicio del servicio. Look for an email with your order confirmation details and an order status tracking link. Your line should be activated no later than 7 p.m. on your start date. Es posible que previamente recibas una notificación ese día para avisarte que se ha activado el servicio, y luego podrás comenzar la instalación.  Si tienes dudas, puedes esperar hasta las 7 p.m. para conectar el módem.

 

For best results, watch the video below and read the full instructions before you begin. If you want, you can download or print the installation guide that will be included in the box with your modem.

If you don't want the app, you can use a web browser on your computer to complete installation.  Solo sigue las instrucciones QuickConnect al llegar al paso 4.

Steps to complete setup

Start by unpacking the box and identifying all the pieces: 

  • Módem
  • Cable de alimentación (negro)
  • Ethernet cables (yellow/white)
  • DSL cable (green) - Not used with C4000XG fiber modem

Next, find a good spot for your modem. Depending on the location of your active internet jack(s), you may have multiple options, or you may be limited to one room. Still, the exact placement has an impact on wireless performance and speeds you'll get on your various devices.

  • Find a place where the modem will have space around it and be as centrally located as possible. 
  • To get a strong wireless signal, avoid closets and closed-off areas.
  • Choose a place with good air circulation that doesn't get too hot, as excessive heat can cause electronics to perform poorly.
  • Don't place the modem close to other electronics, solid appliances, or fish tanks.

Ahora es momento de conectar tu módem. 

1.  Plug the black power cord into a wall outlet and into the power port on the back of the modem. 

2.  For C4000BG/BZ or LG/LZ models, plug the green DSL cable into the green DSL port on back of the modem, then into an active phone jack. Note that the C4000XG fiber modem does not have a DSL port.

3.  Finally, plug the yellow Ethernet cord into one of the Ethernet ports on the modem, and then into your computer's Ethernet port. 

No Ethernet port on your device? If you're using a tablet or a newer laptop, you might not have an Ethernet port on your device. That's okay. If you finish your setup through the app (connecting through mobile data), then you'll be able to connect to WiFi using your WiFi network (SSID) and password printed on the modem label.

If you have a white cord in your modem kit, this is a backup Ethernet cable. You can use it if you want to plug another device (such as a computer or gaming system, etc.) into the modem with a wired connection.

Do you have both Internet AND Home Phone service from CenturyLink?    

If YES, then you must have DSL filters or splitters installed on your phone lines. Open the instructions below. Skip this step if you do not have CenturyLink home phone service.

If you have a C4000BG, BZ, LG or LZ model AND you have CenturyLink home phone service, you will need to install DSL filters on all of your phone cords. Estos son importantes para asegurarte de tener la mejor conexión telefónica y de Internet. Mira las instrucciones detalladas y los diagramas a continuación.

Filters are not needed if you have a C4000XG

Conexión del teléfono al filtro (diagrama)

Enchufa el cable del teléfono en un filtro y luego en el enchufe de pared.

If you have cordless phones, you only need to install a filter on the phone base that plugs in to the wall jack. Other units that plug into an electrical outlet but not a phone jack do not need filters.

Note: Filters are not included in your modem kit. If you have home phone service from CenturyLink, filters should be included at the time of your internet order, and will arrive in a separate package. Si no recibiste estos filtros, chatea con nosotros.

¿Tienes un sistema de seguridad residencial? Chatea con servicio al cliente and ask to have a technician install a whole-home filter on the line outside your home. There is an installation fee for this service.

The status light on the front of the C4000 will change colors as it goes through the installation process, to show you its connection status. 

Luz del estado C4000

During initial boot-up, the status light will blink blue as your modem searches for the CenturyLink network. It will turn fija en color AZUL cuando se haya conectado.

Troubleshooting tip: If the light continues to blink blue, asegúrate de que el cable DSL verde esté bien conectado tanto al módem como a la toma de la pared. If it repeats blinking blue again for more than 5 minutes, then service is not active in that wall jack. Utiliza otra toma o chatea con nosotros para solicitar asistencia.

Be patient! After plugging in your modem, it may take up to 15 minutes for the equipment to install updates and establish a connection with the network.

The C4000LG and LZ models have a small DSL status light on the back side, as shown in the photo. The C4000BG and BZ models have two DSL lights. This light will flash red and green while the modem is syncing with our network, at the same time the light ring on the front is blinking blue.

Once the modem finishes booting up and syncing, you can check the DSL light to confirm the connection to our network.

Note that the C4000XG does not have a DSL port or light.

If the DSL light is VERDE

Esto significa que tu módem está conectado a nuestra red y que la línea está activa. Puedes continuar con el paso siguiente para completar la configuración.


If the DSL light is ROJO

This means your modem is not connecting to our network for one of these reasons:

  • Your service isn't active yet. Wait until 7 p.m. to attempt setup on your service start date, unless you receive a confirmation email before that time saying that service is active.
  • The phone jack isn't active or is faulty. Try plugging the green DSL cord into a different wall jack, if available.


Si la luz DSL continúa roja después de verificar los cables y de haber probado con todos los tomas disponibles, tendrás que  chatear con un agente de servicio al cliente para obtener ayuda. 


Si la luz DSL se encuentra  APAGADA

Esto indica que no hay nada conectado al puerto del módem. Make sure the green DSL cable is firmly plugged in to the wall jack and the DSL port on the modem.

Once the light on the front is blue (and the DSL light on the back, if you have one, is green), it's time to activate your service. You can do this using the mobile app OR the QuickConnect site on a browser — either one will walk you through the steps to sign your subscriber agreement, finish installing service, and create your personal network.

Option 1: On a smartphone connected to mobile data, open the aplicación móvil de My CenturyLink, ingresa a la sección Instalar Mi Nuevo Módem.

Option 2: Plug a computer into your modem directly with an Ethernet cable. Open a web browser and type in to http://connect.centurylink.com (no "https"). Sigue los pasos para completar el proceso de instalación usando QuickConnect.

After completing the setup steps in the app or through the QuickConnect site, check the light ring on the front of the modem  again to verify its connection status.

The light ring is VERDE

¡Una vez que la luz está verde, estás conectado a Internet y puedes estar en línea!

The light ring is ÁMBAR

Si la luz está color ámbar/naranja, significa que el proceso de configuración no está completo aún o no has aceptado el acuerdo de usuario. Utiliza la aplicación móvil My CenturyLink o dirígete a http://connect.centurylink.comy sigue las indicaciones para finalizar la configuración.

The light ring is ROJO

Esto significa que se produjo una falla de conexión. Intenta desconectar todo (DSL y cables de energía), espera unos minutos y repite los  pasos 2 a 4. Si continúas viendo una luz roja, tendrás que chatear con un agente para obtener más ayuda sobre solución a problemas.

You can learn more about how to read the status light on your C4000 modem and use it to check your connection status.

¡PRECAUCIÓN! Do not remove your modem sticker. It includes your default Admin Username and Admin Password, which cannot be retrieved if lost. Your modem could become unusable without them. 

Setup FAQs

Below are some of the most common questions customers ask during the modem setup process.

The initial boot-up can take up to 15 minutes, as the modem installs firmware updates and syncs with our network. The remaining steps will depend on your installation method (the app or the QuickConnect site) and how quickly you go through it. It's a good idea to allow at least 45 minutes to complete setup. Some people may need more or less time than that.

This will depend on the age of your home or apartment and how it was built. In an older and larger home, there may be multiple jacks. In some cases, different providers may have installed jacks over the years. One or more of your jacks should be connected to the CenturyLink network; if not, you'll need to set up a technician appointment to install or activate a jack for you.

If none of the lights are coming on, this most likely means the modem isn't getting power. Check your connections and your power outlet:

  • Asegúrate de que el cable de alimentación esté bien y firmemente enchufado en ambos extremos: en el puerto de alimentación del módem y en el tomacorriente de pared.
  • Asegúrate de que el tomacorriente funcione. You can test this by plugging in another electrical device, or try another outlet.

Note that the C4000XG fiber modem does not have a DSL light.

For all other C4000 models, a red DSL light (on the back of the modem) means it isn't connecting to the CenturyLink network. This can be because the service hasn't been activated yet, or there's an issue with the jack or the modem configuration. You can try these steps to troubleshoot:

  • Check your order confirmation to make sure you've got the right date. Wait until 7 p.m. on the service start date to attempt setup, unless you receive an email before that saying that service is ready and active.
  • Try another phone jack in your home if one is available. 
  • Intenta reiniciar el módem. Unplug everything, wait a few minutes, then plug it in again. This can often resolve a connection issue by clearing the memory and allowing a clean boot-up.

If the problem continues, you will need to call or chat with tech support to get further help.
