CenturyLink FAQs

A "good internet speed" can vary from household to household depending on what you use the internet for and how many people are connected. For example, regular web browsing requires 1Mbps, video streaming requires 3-25Mbps, and video calling typically needs about 3-6Mbps. Generally, the average household not participating in excessive video streaming or online gaming could consider 15-20Mbps a "good" internet speed.
It's okay if your speed test results are a little above or below your plan's listed speed. Several factors can vary the results of speed tests, but in general, internet speed tests like the one on this page are a great way to estimate your current provider's upload and download speeds to your devices at your current location. To make your speed test results as accurate as possible, be sure to follow these steps prior to beginning each test: restart your modem and router, stop any internet use, restart your computer, and clear your web browser’s cache. If your speeds are consistently much lower than expected, you can reach out to CenturyLink at the appropriate phone number above for help.
Typically, just a few seconds. Internet speed tests are a quick way to receive your current upload and download speeds from your current internet service provider.
Not impressed with your current CenturyLink internet connection? Try moving your router to a more central location, adding a WiFi extender, and simply turning your modem off and on again. These changes can all potentially improve your internet speed test results. Still not impressed after trying those changes? Use our WhistleOut search tool to compare faster internet plan options.
When you are using the internet to load web pages or download anything such as photos and videos, your download speed will impact that experience. When you are uploading content to the internet such as image files or live streaming video, you will rely on your upload speeds.
If your internet speeds are consistently slower than expected, consider the number of devices connected or the number of people currently using your WiFi. A greater number of people and devices connected, as well as what each person is using the internet for, can impact the relative speed of your internet. If your internet speeds still haven't improved after reducing the amount of people and devices connected, you may want to consider increased internet congestion, website/server limitations, corrupted web browsers, adware or spyware, wired vs. wireless connection, the type of modem you're using, your computer's processing speed, and your operating system's efficiency. You can also contact CenturyLink at the appropriate number above if you have specific questions regarding your internet speeds.
