AT&T Internet Speed Test FAQ

AT&T’s average Internet speeds are based on the last twelve months of speed test data. Speed tests we analyze to show statistics for AT&T on BroadbandNow are sourced from the M-Labs database, which aggregates AT&T speed tests run on BroadbandNow as well as in Google’s search result tools. We use IP-verification to match visitor IP addresses to known AT&T Internet IP addresses. This helps us avoid manipulation of the results from repeat or non-network users.

AT&T Internet Download and Upload Speeds

Download speeds are higher than upload speeds on most of AT&T’s Internet plans. Prioritizing download speeds is normal because most customers request more data than they transmit in the form of video, websites, etc. AT&T has been building out true “fiber to the home” networks in recent years. In AT&T Fiber areas, customers can get upload speeds that equal their download speeds. This is called symmetrical speed, as opposed to the asymmetrical speeds on AT&T’s IPBB plans.

AT&T Ping and Latency

AT&T has normal ping and latency in the context of other Internet providers. Most customers should see results well below 100ms.
