Check your AT&T internet speed
To Begin a Speed Test:
Prepare your network to get accurate results
- Delete your browser’s Cache, Cookies, and Temporary Internet Files. To find out how please go here
- Stop all downloads, streaming, applications, or programs that may be using your Internet connection
- Use a wired connection directly between your device and the gateway, exclude third party routers for this test
- Eliminate traffic being used by all devices connected to the gateway except for the device with the speed test in progress, disable WiFi if necessary
- Check if your device can handle the speed you are subscribed to by downloading the PC Maintenance Toolbox
- Reboot your Residential Gateway
Launch the AT&T recommended speed test site at att.com/speedtest
- Enter your AT&T e-mail address to help us improve our service (optional)
- Click the START TEST button
- Allow 30-60 seconds for your test results
- Review the Download and Upload speed then compare it to your subscribed speed
- Rerun the test if needed by using the button in the test results section
Speed test results still slow?
- Go to our myAT&T app and let us test your service, if we find something we can begin resolving the issue
- Reboot your residential gateway if you have not done so, regular use leads to low memory and pending processes for the gateway’s operating system as with most networking devices
- Check the Ethernet cable for any defects and replace if necessary
- Periodically clear your browser’s cache
- Scan your PC or device for any Spyware, Virus, or other malicious programs and take action to remove them
- Avoid running multiple firewalls, or disable firewall
- Avoid using VPN connections and Internet Proxy servers
Understanding the results:
Why are my speed results good but streaming media, or gaming is slow?
- A speed test will measure your download and upload speed but does not measure the quality or stability of your connection. To measure quality and stability it is recommended to do a ping type test to identify if any packet loss exists
What is Mbps or Kbps?
- This is the unit of measure for your Internet speed
- Mbps - Megabits Per Second
- Kbps- Kilobits Per Second
- 1000 Kilobits is 1 Megabit
Why do other speed test sites give me different results?
- Speed test sites use different server locations, it is recommended to use the nearest server to you
- While it is good practice to test your speed with alternate speed testing sites, please be aware the results may vary based on location
