AT&T Data Calculator - Estimate Your Internet Data Usage

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.

Take steps to boost internet and device speed.

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

Number of devices and activities

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 those with 1-2 radios (like smartphones and tablets) may not be able to reach faster speeds.

Device type and age

These conditions may weaken Wi-Fi and slow speed:

Devices being too far from the Wi-Fi gateway

Construction materials like concrete or rebar

Electrical appliances like microwaves and baby monitors

Interference from neighbors’ Wi-Fi networks

Wi-Fi signal strength

Move Wi-Fi devices closer to your gateway.

Turn off or disconnect devices you're not using.

Improve device speed

The speed you get on devices connected to your home Wi-Fi can vary. The number of devices you connect to Wi-Fi, how you can see them, their age and type, and Wi-Fi signal strength all can affect speed.

Speeds may vary by hardware  and software capabilities.

Newer devices will have faster speeds over.

Wired connections are always faster than Wi-Fi connections.

Laptops will generally be faster than phones.
