Cox device speed test

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.

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.
