If you're dealing with a slow internet connection, we feel your frustration. It can be hard to pinpoint the exact cause, since a range of factors can cause slow speeds. We can walk you through several things you try to fix a slow connection.
Start by learning about how internet speed works below. Then, run through our troubleshooting checklist before calling on a technician for help. You can also follow our video instructions at the bottom of the page.
NOTE: If you have one of these (called a SmartNID), then you have CenturyLink Fiber with Premium WiFi. Some of the instructions on this page will not apply to you. Visita nuestra Premium WiFi troubleshooting page for specialized help.
Las diferentes actividades en línea utilizan el ancho de banda disponible. Cuantos más dispositivos tengas activos al mismo tiempo, más se reducirán las velocidades.
Web hosts: Content providers and websites manage high-bandwidth sites and platforms worldwide. If a provider is getting more demand than their servers can handle, this can cause buffering or slow load times on that specific platform.
A tech support agent would walk you through several steps to isolate the source of the issue. In other words, you need to try lots of different things that could fix your slow internet if you're not sure what's causing the problem. Open each section to go through the checklist and questions.
It's helpful to find out whether the slowdown is happening with your core service line, or whether it's a WiFi or device problem. To do this, follow the steps below.
Ingresa al modem settings GUI from a device connected to your network, and look at the Modem Status. The connection status will show you if there's an issue with your line. Check the Downstream Rate (download speed) in the modem status table.
In this example, two lines are pair-bonded for a total Downstream Rate of about 80 Mbps. Your modem may have one or two lines, depending on your internet service.
Modems can slow down after running for a while. Often, a poor connection can be fixed by restarting your modem/router. This clears the memory and resets the connection. Rebooting also gives you the best WiFi signal by allowing the modem to select the channel with the least interference. If you're needing to reboot your modem often, it's probably time to replace it!
Si no tienes una contraseña segura securing your network, anyone close to your home could access your WiFi network and slow it down by "piggybacking." Maximize performance with a secure personal network.
CenturyLink modems update their firmware automatically through the network, so typically you don't have to do anything. However, if you're having connection issues, it's worth checking for firmware updates in the modem settings. This is key to making sure your equipment keeps running as efficiently as possible.
Fiber internet has requisitos de equipo específicos para trabajar con la tecnología de fibra óptica. With faster speeds, you need to make sure your modem can keep up.
What feels like "slow internet" is often a weak WiFi signal. It's good to remember that wireless speeds are almost always slower than wired speeds over the same network, due to interference and signal loss.
The easiest way to do this is to disable wireless in your modem settings, wait a few minutes, then enable it again.
Location matters! You might be surprised by how much your internet speed can be impacted by where your router (modem) is placed. Find a spot up off the floor and centrally located in your home, or in the area closest to most of your connected devices.
Your WiFi signal gets weaker as you move farther away from your router.
All kinds of electronic devices in your home can slow down your WiFi connection, including microwaves, cordless phones, Bluetooth devices, TVs, security systems, baby monitors, and more. Si tienes un módem más nuevo, opt for a 5 GHz frequency signal to get a stronger connection and avoid some of the congestion from surrounding devices that use the 2.4 GHz band.
5 GHz gives more signal strength and faster speed (over a shorter range) compared to 2.4 GHz.
Physical obstacles can also slow down your WiFi speed. Observa si hay algún elemento que se encuentre entre el enrutador y tus dispositivos conectados:
Do your best to move the router so that these things are not blocking the path between it and your main connected devices.
Coloca tu enrutador en algún lugar abierto para mejorar la intensidad de la conexión. Evita los armarios y las estanterías abarrotadas.
Evita colocar tu enrutador cerca de electrodomésticos pesados y densos y de objetos grandes de metal o vidrio.
If your signal is weak in specific areas farther from your router, a extensor de WiFi can increase coverage. It's important to place any extenders close enough to the modem/router to receive a strong signal, as this same signal will then be repeated to the more distant devices.
Your internet connection and your WiFi are only part of the speed equation. Your devices also play a big role.
Some devices, especially older ones, simply are not capable of certain connection speeds. And those slower devices can actually block traffic from other devices and end up slowing down your whole network. Check the maximum speed of your devices, especially those made more than a few years ago.
You can also compare speed results on different devices to determine if there's a slowdown on one particular device. Slower devices may need to be replaced if they're causing performance issues.
Los dispositivos más antiguos pueden ralentizar su rendimiento, incluso con una conexión a Internet rápida .
Los virus y malware can slow down your whole system. Make sure every device is protected. Install well-rated software de seguridad, keep it updated, and run security scans at least weekly. Los suscriptores de Internet de CenturyLink pueden obtener Protección de McAfee for free on up to five devices.
Your web browser (Chrome, Edge, Safari, Firefox, etc.) plays a role as well. Make sure to keep your browser up to date, as well as all browser plug-ins and extensions. You may also want to clear your browser cache on a regular basis.
Los dispositivos pueden verse afectados por tener demasiadas aplicaciones ejecutándose.
Sometimes the simplest solution is one that people skip. It's worth taking a few minutes to make sure your physical connections are good.
Check all cords and cables closely. Children, pets, and furniture can cause wires to be crimped or cut. If you do discover any damaged wiring, learn how to get it fixed.
Check to make sure both ends of all cords are firmly plugged in. You might be surprised at how many times an issue is caused by a loose wire.

Do you also have CenturyLink Home Phone service?
If you have both internet and home phone service from CenturyLink, then you will need DSL filters on all landline phones in the household. Esto garantiza que tu señal de Internet no interfiera con la línea fija.
Enchufa el cable del teléfono en un filtro y luego en el toma de la pared
Nota: si tienes teléfonos inalámbricos, solo tendrás que instalar un filtro en la base del teléfono que está conectado a la toma telefónica de pared. No se necesitan filtros en las unidades inalámbricas conectadas únicamente a un tomacorriente.
Asegúrate de que no haya un filtro instalado entre el módem y la toma de pared.
El cable DSL que se conecta desde el Módem al toma de la pared no debe tener filtro.
Si quieres conectar el módem y el teléfono a la misma toma de pared, puedes utilizar un divisor DSL, como se muestra en el siguiente diagrama.
Or, use a DSL splitter to plug a phone and a modem into one wall jack
If you're a "do it yourself" kind of person, you can check to see whether there's a problem with the network signal by testing your line at the network box (NID). In most cases this can also be accomplished by signing in to your modem settings and checking your connection status.
Once you've gone through the checklist, run the prueba de velocidad de Internet to see your current download speed. You can compare this to your plan speed in My CenturyLink. Keep in mind that the plan speed means total bandwidth. After running a few speed tests, which statement best describes your situation? Haz clic a continuación para ver las soluciones.
If you frequently get slower connection speeds than you should, then there may be a problem with your network line or equipment. Puedes hacer dos cosas:
If your test results are pretty close to your plan speed, you may simply need faster service. En este caso, tienes dos opciones:
Upgrade your service. See if you can upgrade to a faster internet plan. Sign in to My CenturyLink en la web or in la aplicación and check Services for an available speed upgrade.
Agrega una segunda línea. In areas where a higher speed plan isn't available, a popular solution is to double your bandwidth by adding a second internet line.
