About Sonic Internet

Technology

Fiber (10 Gbps FTTH), DSL (Fusion, FTTN)

Coverage

Northern California (Bay Area, Sacramento, Santa Rosa)

Typical Download

50-10000 Mbps

Typical Upload

5-10000 Mbps

Sonic Speed Tiers & Plans

PlanDownloadUploadPrice
Fiber 1 Gig1000 Mbps1000 Mbps$40/mo
Fiber 10 Gig10000 Mbps10000 Mbps$40/mo

Prices and speeds are approximate and may vary by location. Promotional pricing may differ from regular rates.

Common Sonic Issues

Limited geographic availability (Northern California only)
DSL speeds much lower than fiber (50-100 Mbps typical)
10 Gbps plan requires 10 GbE hardware and Cat 6a cabling
Wi-Fi rarely reaches full fiber speed without premium router
Some areas only have DSL with no fiber upgrade timeline
Router provided may not cover larger homes adequately

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

Bufferbloat Detection

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

Jitter Analysis

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

Connection Health Grade

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

Sonic FAQ

Is Sonic throttling my internet?
If your speed test results are significantly lower than what your Sonic 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 Sonic'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 Sonic?
Sonic offers download speeds of 50-10000 Mbps and upload speeds of 5-10000 Mbps, depending on your plan and connection type (Fiber (10 Gbps FTTH), DSL (Fusion, FTTN)). 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 Sonic internet slow even with a fast plan?
Several factors can slow down your Sonic 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 Sonic have bufferbloat problems?
Bufferbloat can occur on any ISP connection, but it is especially common on Fiber (10 Gbps FTTH) 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.
