Bufferbloat particularly bad during evening congestion windows

How Pong.com Helps Suddenlink 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 Suddenlink connection can actually do.

Bufferbloat Detection

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

Jitter Analysis

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

Connection Health Grade

Get an A-F grade for your Suddenlink 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 Suddenlink 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 Suddenlink's network, Pong.com tests across the real internet, giving you speeds that match your actual experience.

Suddenlink FAQ

Is Suddenlink throttling my internet?
If your speed test results are significantly lower than what your Suddenlink 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 Suddenlink'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 Suddenlink?
Suddenlink offers download speeds of 300-1000 Mbps and upload speeds of 20-50 Mbps, depending on your plan and connection type (Cable (DOCSIS 3.1)). 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 Suddenlink internet slow even with a fast plan?
Several factors can slow down your Suddenlink connection: bufferbloat (high latency under load), Wi-Fi interference from neighboring networks, outdated modem or router firmware, network congestion during peak hours, or issues with your home wiring.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 Suddenlink have bufferbloat problems?
Bufferbloat can occur on any ISP connection, but it is especially common on Cable (DOCSIS 3.1) 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.
