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.
