The AT&T Speed Test shows you your baseline speeds. Baseline speeds are determined by using the AT&T servers closest to you to measure the speed between your devices (including computers, smartphones, tablets, game consoles, and smart TVs) and the internet. The speed test takes less than a minute and performs 2 key measurements:

According to our AT&T wireless speed test data, the average AT&T 4G LTE download speed is about 13 Mbps. That’s slightly above the 12 Mbps it advertises. While this looks good, keep in mind that internet speeds fluctuate, especially mobile internet. The 13 Mbps average comes from nearly 13,000 speed tests that ranged from 0 Mbps to 241 Mbps.

And this health check means a smooth and reliable speed test performed on your broadband Internet. The AT&T speed test is done by using a third party reliable speed test service. This testing tool checks your broadband speed by sending huge chunks of bytes and receiving huge chunks of bytes to determine the actual Internet speed of your connection.

As of July 2021, AT&T Internet’s average download rate is 179.36 Mbps. Across their coverage area, the average latency on AT&T Internet Internet speed tests is -1ms. For context, wired Internet connections usually have latency in the 5–70ms range. Satellite connections, on the other hand, can be closer to 500–800ms.

You can also use our AT&T internet speed test to gauge your AT&T wireless speeds. To test your AT&T wireless internet speed, disable Wi-Fi on your mobile device and begin the speed test. You’ll get download speed, upload speed and ping results just like you would with the AT&T internet speed test. Average AT&T wireless internet speeds: 41.23 Mbps

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.
