Cox speed test

Let’s run a quick check-up

Your speed test results may not match your plan speeds—but don't worry, that's normal. Browsers have different capabilities and may give you different results, particularly on high-speed connections. If you want something to compare against, try downloading the Speedtest app for some extra accuracy.

Understanding your device speed

What affects my device speed?

If you have some questions about your test results, here are potential factors that could be affecting your speeds.  

Your particular connected device and/or cable could be limiting your speed. Most hardwired devices are limited to 940 Mbps download speeds. If you’re using a wired connection, make sure you’re using an up-to-date cable like a CAT-6 ethernet cable.   

The more connected devices there are, the less speed there is to go around. Your home network can slow down if there are a lot of smart devices being used at the same time.

If you’re using wifi, get closer to your modem or Panoramic Wifi Gateway for a faster connection.  

Certain objects can slow down your wifi speed if they’re between you and your modem including electronics, walls, doors and other building materials.

How to improve device speeds

Boost your everyday connections

Try these DIY tips for a faster Internet connection.

Make a fresh start

Reboot your modem and smart devices by powering them off then back on. Set any major device software updates or cloud backups to run overnight.

Location, location, location

Place your router on a counter in a central area of your home. Make sure it’s elevated over three feet high, not in a cabinet and away from walls, metal objects and other electronics.  

Check your equipment

Take a look at your router to make sure it’s operating on the 802.11ac standard and see if it’s on our list of certified cable modems. If your Gateway is four years or older, it’s time to upgrade. When buying Gateways or other wifi devices, look for terms like AC/AX, Dual Band, wifi 5 or wifi 6.  

Look to your other devices

Check in with the smart devices in your home to see if they’re using up more bandwidth than necessary. If you have a Homelife HD Camera, you can adjust to a lower video quality setting or turn it off when not needed.

Take calls from video to voice

If you notice buffering or fuzziness when on a video call, try turning off your camera to regain call quality.

Stretch your wifi signal

Device speed test FAQs

The test measures your current connection’s performance - the ping, download and upload speeds - between your device and a test server. The test mimics your online activity by downloading / uploading sample files and recording speeds. Speed tests are a good way to start troubleshooting. The Cox Speed Test tool works using testing from Ookla, a global leader in broadband speed testing applications, and creates a series of multiple connections to nearby test servers to measure and gather your speed performance data. All samples are sorted by speed and the fastest two results and the bottom quarter of the remaining samples are removed. The remaining samples are then averaged, giving you your speed test results.

No, you don't need to be connected to a Cox network but connecting your device directly into your Cox network will yield the best results. You can also run the test with multiple devices; it will slow the test down and give an inaccurate reading so connect one device at a time.

A lot of things can negatively impact your results. To get a more accurate reading during your speed test, try the following:

 

  • Run the test on a computer with a wired connection to your gateway.
  • If you don't have a wired connection, run the test near your modem or router to make sure nothing is blocking your wifi signal.
  • Make sure other devices aren't using the internet connection - too many devices on the same network might slow down your speed.
  • Check that your modem and router are newer models that meet your internet service package's minimum requirements.
  • Looking for better performance? Invest in newer devices; older ones may not have the ability to keep up with your service's speed needs.

We can’t guarantee that the results of the speed test will match your service because of the external factors that impact your speed, like your devices’ hardware and operating systems. The device (phone, laptop, etc.) used with the tool can play a very important role since devices can have varying max speeds (most hardwired devices are limited to 940 Mbps due to port limitations). Other factors include the browser which you use to run the speed test, processing power of your personal computing equipment, apps running on your computer, the nature and quality of your home network connection, third party networks you may be connected to, and the performance of the websites you visit on the internet.

 

Download speed tells you how quickly you can pull data from the internet to your computer or device.

 

Upload speed tells you how quickly you can send data from your computer or device to others.

 

IP address is your unique "signature" that identifies your device on the internet or network.

 

Test server is the local or shared network where your speed test is running.

 

Ping is how long it takes your device to connect to a remote destination (also called latency).

 

Jitter is how consistent your device speed is when it's connected to the internet.
