FAQ

What are download speeds?
Download speeds are how quickly data travels from the internet to your device. A higher download speed means you can stream, download files, or access websites faster.

What are upload speeds?
Upload speeds reflect how fast data travels from your device to the internet. A higher upload speed makes posting files or images to social media or other sites faster.

What factors affect my download and upload speeds?
Your speed results may vary based on many things, including but not limited to:
  • Device or connection type
  • Number of connected devices
  • Network congestion

What is latency?
Latency (ping) is how long it takes data to travel from your device to another location and back. High latency can cause issues with video calls or online gaming.

How does this speed test differ from the Smart Home Manager Wi-Fi gateway test?
This speed test checks the speed between your smartphone, tablet, computer, or other device and the internet. You can run the test through a cellular (mobile) network, a wired broadband connection, or your home Wi-Fi.

A gateway speed test checks the speed between your AT&T Wi-Fi gateway and our network. It reflects the actual speed coming into your home. Test your AT&T gateway speed with AT&T Smart Home Manager.
