Why is my internet connection slow?

To make sure you're getting the fastest speed possible, you can check and fix a few things before running a speed test. It's a good idea to optimize your wired internet connection, as shown below, before troubleshooting wireless (WiFi) issues. 

Do you notice that your internet speed seems significantly slower at some times than at others? Learn more about what may be causing this and what you can do about it.

Troubleshoot a slow connection

You can often improve your connection speed by checking your wiring, modem and devices on your home network. Going through each of the steps below can also help determine if there's an issue on your end (with your home equipment/setup) or on our end (with the CenturyLink network) that needs further attention.

Connect one device and close all programs
Make sure there's no filter on your modem
Check for damaged or unplugged cables
Check your devices and reduce bandwidth usage
Check your modem performance
Consider the role of content providers
Special requirements for Gigabit users
Check your outdoor wiring

What's next?

Once you've checked everything listed above, trying running another speed test. Remember to run the test a few times to get more accurate result.

My wired speed test is great

If you verified through the speed test that your wired speed is good but you're still not getting the performance you expect, it could be your wireless signal that's slowing you down. Try optimizing your wireless speed, or consider whether a WiFi extender could help you boost your coverage.
