Is your business Internet speed fast enough to keep up with your daily operations? Learn how to conduct a speed test and use the results to get the connection you need.

How the Speed Test Works

The Cox Business Internet Speed Test checks your connection’s download and upload speeds using your browser. It also allows you to assess your device’s connection to the Internet and explore what steps you can take to improve performance.

For best results, test your speed by plugging directly into your modem. Your subscription speed is the speed delivered to the modem, not to your wireless devices. This is why testing speeds on a wireless connection may not deliver the results you expect. Other factors, like device capability limits, may also result in slower speeds.

Understanding Your Device Speed

Factors That Can Affect Your Results

If your Internet speed test results appear slow, it could be due to a number of reasons, not necessarily your connection. If you’re experiencing slow speeds, follow these following steps to help improve your results.

Connect Using an Ethernet Cable

Wireless connections tend be slower than wired ones. Use an Ethernet cable to connect your device directly to the Internet and see if it helps boost the speed.

Reboot Your Equipment

Power off your router, modem and any devices in use. Then restart to improve performance.

You can also reboot your device in Cox Business MyAccount online or in our mobile app. Learn more

Close Programs

Running programs and apps can affect your test results. Close them to help eliminate network congestion.

Update Software

Make sure you have the latest software updates installed on your computer’s browser and operating systems.

Check Device Limits

Not all devices are equipped to support high speeds. Check your owner’s manuals to find out what your systems can handle.

Adjust Router Placement

The further your router is from your devices, the slower your connection will be. Make sure your router is in an open, central location. Avoid placing it next to objects that can interfere with the WiFi signal, such as large file cabinets, printers and closets.

Understanding Your Results

A speed test will help you understand three main components of your business Internet connection.

Download Speeds

This number is also measured in megabits per second (Mbps) Mbps and reveals how quickly your device receives data from the Internet.

Upload Speeds

This number is measured in Mbps and shows how quickly your device sends data back to the Internet.


Also referred to as ping or jitter, this number is measured in milliseconds to indicate the time it takes for data to travel from devices on different networks.

Business Internet Speed Test FAQs:

Speed test results only reflect a given time frame, so be sure to connect to your nearest server location and run multiple tests to fully understand yours. Here are some ways to test your Internet speed:


  • Use Multiple Connections. Compare speeds by testing both your wireless and Ethernet connections. Remember, your subscription speed is the speed delivered to the modem—not to your wireless devices. This is why testing speeds on a wireless connection may not deliver the results you expect.
  • Test at Different Times of Day. Businesses using cable Internet share their connection with neighboring buildings, meaning your Internet connection can be affected during peak business hours. Test at different times of the day to see when your connection is congested due to Internet traffic.
  • Multiple Devices. Using multiple devices simultaneously can impact your bandwidth and slow your connection. Test the connection using just one device, then add more to see how many devices your Internet can support at one time without compromising speed.
  • Check Different Rooms. Test your Internet speed in the same room as your router, then move further away to see if you need to relocate your equipment.

A speed test will reveal download speed, upload speed and ping time on any device connected to your Internet. You can then use these results to figure out how you can improve your connection.

Your speed test results can reveal whether you’re getting the correct Internet speeds, what outside factors could be affecting your connection and the steps you can take to help improve performance. If you’ve followed all the recommended steps and you’re still experiencing slow speeds, contact your Internet service provider to have a professional check the connection.

The right upload and download speeds for your business will depend on the number of users and the tasks being performed. Small businesses with basic digital needs and less than 15 users can rely on up to 100 Mbps download speeds and 35 Mbps upload. Growing and large businesses with multiple users and devices should consider a fiber optic connection for consistent fast speeds up to 1Gbps. A fiber optic connection can support high demands, such as livestreaming, Voice over Internet Protocol services and remote working.

Tasks like video conferencing take up a lot of bandwidth – and if you have multiple users all doing different tasks online, it can have a significant impact on your Internet performance. While a single user can run a video chat conference with upload speeds less than 35 Mbps, an entire office may need higher speeds for a more reliable Internet connection. Fiber optic download speeds of up to 1Gbps will offer the most reliable connection for multiple users and uninterrupted video conferences.

Business Internet 50


Ideal for:

  • Up to 5 users at once
  • Web, email and simple online daily tasks
  • Point-of-sales systems (POS)

Business Internet 200


Ideal for:

  • Up to 20 users at once
  • Video conferencing and streaming
  • File transfer and backup

Business Internet 1Gbps


Ideal for:

  • 20-100+ employees
  • Near real time experience for all users and devices
  • Simultaneous video conferencing

The fastest business Internet speeds are offered by a fiber optic Internet connection. Fiber optic Internet offers symmetrical (equal upload and download) speeds up to 1Gbps.
