How Does the Cox Speed Test Tool Works?

The speed test first measures your internet connection’s latency. It transmits a small amount of data from your device to the nearest testing server to check the latency. The tool then calculates how long it takes to receive the response. This millisecond measurement is latency.

The speed test tools then compute the upload and download speeds. It creates multiple simultaneous connections between the test server and your device to request and send data. The test calculates how much data is received and sent in a set amount of time. It gives you the upload and downloads speed after calculating the results.

Speed Test Factors

The Cox speed testing tool measures the following three aspects.

Download Speed:

It is the speed at which the device receives data from the internet. Your device receives data from the testing server enabling the tool to measure the download speed. It is typically assessed in Mbps or Gbps.

Upload Speed:

It is the speed at which your device sends data to the internet. Your device transmits data back to the testing server, which allows the tool to measure the upload speed. The upload speed is typically assessed in Mbps or Gbps.


Latency is the time it takes for data to transmit from your device to the testing server and back to your device. It is usually measured in milliseconds. A lower latency rate determines a better internet connection for online gaming and live streaming.

Why is my Cox Internet Speed Slower than Advertised?

Your Cox internet speed can be slower than advertised for familiar reasons.

  1. Your Cox internet plan needs to be faster and sufficient for your needs. 
  2. Your router may be faulty. It means that the placement of the router is not correct.
  3. The speed of the Cox internet also slows down when too many people are using your Wi-Fi simultaneously
  4. The router or modem that you are using is out-dated.
  5. Coaxial cables are faulty.
  6. The network is overflowing during peak hours. This issue is prevalent in densely populated areas.
  7. The ISP is throttling speeds while experiencing peer-to-peer traffic.

How Can I Enhance my Cox Internet Speed?

Here are some simple steps that you can follow to improve your Cox internet speed.

  • If you are facing weak Internet speeds on specific devices within your home while others remain unaffected, the positioning of your router could be the underlying issue. Change the position of your router. 
  • Get an Upgraded Router. Most modern routers use dual-band technology. It means they can transmit both 5 GHz and 2.4 GHz frequencies, which provide the best internet speed.
  • Consider a Wi-Fi Extender. With a Wi-Fi extender, you can shorten the distance between the Wi-Fi signal and your devices, thus improving each device’s speed and performance.
  • Connect with an Ethernet Cable. Ethernet cables offer higher data transfer speeds due to their direct physical connection to the Internet infrastructure, resulting in more efficient and reliable data transmission.
