Understanding internet speed
What affects my internet speed?
The speed of your internet connection to your Wi-Fi® gateway is pretty consistent. You can check it with AT&T Smart Home Manager.

However, the speed you get on devices connected to your network can vary. The number of devices you connect to Wi-Fi, how you use them, their age and type, and Wi-Fi signal strength all can affect speed.
  • NUMBER OF DEVICES AND ACTIVITIES

    All connected devices share your home internet connection. Trying to do too much at the same time can slow your speed:

    • Using multiple devices
    • Streaming
    • Gaming
    • Video conferencing
  • DEVICE TYPE AND AGE

    Wi-Fi devices connect to your home network using wireless radios and tech.

    • Newer PCs and devices are usually faster than those using older Wi-Fi tech
    • Older devices or devices with 1-2 radios (like smartphones and tablets) may not be able to reach faster speeds
  • WI-FI SIGNAL STRENGTH

    These conditions may weaken Wi-Fi and slow speed:

    • Locating devices too far from the Wi-Fi gateway
    • Obstacles like walls, doors, or floors
    • Construction materials like concrete or rebar
    • Electrical appliances like microwaves and baby monitors
    • Interference from neighbors' Wi-Fi networks
