Common Spectrum Issues

Very low upload speeds relative to download (asymmetric cable)
Peak hour congestion in densely populated neighborhoods
Bufferbloat causing lag during simultaneous streaming and gaming
Periodic speed drops requiring modem reboot
Wi-Fi interference from Spectrum-provided routers on crowded channels
Inconsistent latency affecting real-time gaming and video calls

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

Bufferbloat Detection

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

Jitter Analysis

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

Connection Health Grade

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

Spectrum FAQ

Is Spectrum throttling my internet?
If your speed test results are significantly lower than what your Spectrum 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 Spectrum'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 Spectrum?
Spectrum offers download speeds of 300-1000 Mbps and upload speeds of 10-35 Mbps, depending on your plan and connection type (Cable (DOCSIS 3.1), Fiber (expanding)). 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 Spectrum internet slow even with a fast plan?
Several factors can slow down your Spectrum 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 Spectrum 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.
