How the Cox speed test works

An internet speed test shows the internet connection speed you get from your internet service provider. Our Cox internet speed test finds your stable internet speed rather than the fastest speed. This gives you the most accurate picture of what speeds you’re getting.

How do my speeds compare?

Compare your Cox speed test results to Cox’s average internet speeds calculated from thousands of our Cox speed test results. Cox’s average download speed from 2023 – 2024 was 263 Mbps while its average upload speed was 36 Mbps. Cox’s average latency was 14 ms.

Cox’s average download speed and latency results were better than the U.S. average, but Cox fell behind when it came to average upload speeds.

The Cox advertised speeds didn’t line up with your actual speed test results?

Internet speeds can vary, and there’s no way to guarantee that the speed your provider advertises will be the one you actually get in your home. In many cases, you’ll find that your speed is still suitable. If your speed doesn’t line up with Cox’s advertised speeds and isn’t meeting your needs, you can shop around for a new internet service plan.

How do Cox’s average speeds compare to competitors?

See how Cox’s average speeds compare to other top internet providers such as AT&T, Xfinity and Verizon. Cox has the fastest average download speed of major ISPs at 263 Mbps, followed by Google Fiber, Xfinity and Spectrum.

How much speed do I need?

The truth is that not everyone needs the fastest internet speeds available. Instead, the speeds you need really depend on what you’ll be using your internet for. People who regularly stream videos or play online games will require faster speeds, while those just browsing the internet or streaming music may be fine with slower speeds. It also depends on the number of people in your home, as more people on the internet will require faster speeds.

Tips for getting accurate Cox speed test results

Before starting your test, there are a few steps you’ll want to take to ensure it is accurate. These steps are not necessary to take the test. 

• Connect your computer directly to the modem using an Ethernet cable. If your internet plan advertises speeds above 100 Mbps, use a Cat5e, Cat6 or Cat7 Ethernet cable for the best results.
• Disconnect any other devices that use the internet. This includes any device that may be connected to your Wi-Fi network, such as smartphones, tablets, smart TVs, Wi-Fi enabled cameras, etc. These devices can use up bandwidth and interfere with your test results, even if you aren’t actively using them.
• Close any apps or web pages on your computer that may be using up bandwidth, such as video and music streaming apps or sites.

How to fix slow internet

Here are a few things you try to improve your internet connection:

• Restart your equipment – Usually, the first thing you should try when you’re experiencing internet issues is to reboot your equipment. Unplug both your modem and router for 10 – 20 seconds then plug them back in.
• Optimize your router settings – Routers have different settings you can test out depending on your internet activities. Some routers have entertainment settings that prioritize bandwidth while you game or stream. You can also play with your Request to Send (RTS) thresholds to improve your Wi-Fi.
• Upgrade your equipment – Upgrading outdated equipment can improve your internet connection. If your equipment is out of date and cannot support your current Wi-Fi speed, your connection will be slower than what you are paying for.
• Reconfigure router antennas – If your router has external antennas, try moving them around at different angles to improve your Wi-Fi signal.
• Add a Wi-Fi extender to your network – Purchasing a Wi-Fi extender to add to your home network can help extend your Wi-Fi coverage to hard to reach areas of your home.
