Common AT&T Issues

Legacy DSL customers stuck on slow speeds with no fiber upgrade available
DNS resolution delays on default AT&T DNS servers
Wi-Fi dead zones with provided gateway hardware
Latency spikes on DSL connections during rain or wet weather
BGP routing inefficiencies adding extra hops to certain destinations
IPv6 transition issues causing intermittent connectivity problems

How Pong.com Helps AT&T Customers

Most speed tests only measure raw throughput inside your ISP's network. Pong.com goes further, testing across the real public internet to reveal what your AT&T connection can actually do.

Bufferbloat Detection

Discover if your AT&T connection suffers from high latency under load. Bufferbloat causes lag and stuttering even on fast connections.

Jitter Analysis

Measure the consistency of your AT&T connection. High jitter means unreliable performance for gaming, video calls, and streaming.

Connection Health Grade

Get an A-F grade for your AT&T connection based on speed, latency, bufferbloat, and stability. Know exactly where you stand.

Real-World Experience Scores

See how your connection performs for specific activities: 4K streaming, video conferencing, competitive gaming, and web browsing.

Speed History Tracking

Track your AT&T speeds over time. Spot trends, identify peak-hour slowdowns, and catch degradation before it becomes a problem.

Public Internet Testing

Unlike tests that measure inside AT&T's network, Pong.com tests across the real internet, giving you speeds that match your actual experience.

AT&T FAQ

Is AT&T throttling my internet?
If your speed test results are significantly lower than what your AT&T plan advertises, throttling or network congestion could be the cause. Run a test on Pong.com to check your real speeds. Pong.com tests through the public internet (not inside AT&T's own network) so you get an accurate picture. Try testing at different times of day to see if speeds drop during peak hours.
What speeds should I expect from AT&T?
AT&T offers download speeds of 300-5000 Mbps (Fiber), 10-100 Mbps (DSL) and upload speeds of 300-5000 Mbps (Fiber), 1-20 Mbps (DSL), depending on your plan and connection type (Fiber (AT&T Fiber), DSL (legacy IPBB)). On a wired Ethernet connection, you should typically see 70-90% of your plan's advertised speed. Wi-Fi speeds will be lower due to signal attenuation and interference. Use Pong.com to verify your actual speeds.
Why is my AT&T internet slow even with a fast plan?
Several factors can slow down your AT&T connection: bufferbloat (high latency under load), Wi-Fi interference from neighboring networks, outdated modem or router firmware, network congestion during peak hours, or issues with your home wiring. Pong.com tests all of these factors in a single test, including bufferbloat detection, jitter analysis, and a connection health grade.
Does AT&T have bufferbloat problems?
Bufferbloat can occur on any ISP connection, but it is especially common on Fiber (AT&T Fiber) connections. It causes your latency to spike when your connection is under load (e.g., downloading a file while on a video call). Pong.com specifically tests for bufferbloat and grades it from A (excellent) to F (severe). This tells you more about your real connection quality than download speed alone.
