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 DSL 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.

AT&T has DSL as well as fiber networks. Their fiber networks are often used for business services only. However, that has begun to change, and customers in many parts of the AT&T service area can get speeds up to the gigabit range for home use.
