They're not the same problem. This guide helps you figure out which one you have, what to tell your ISP, and what to do if they won't fix it.
Start Here — Run the Tests →You're not getting the megabits you're paying for. Downloads are slow. Videos buffer.
Your speeds look fine on paper but calls drop, games lag, and video meetings fall apart.
It takes about 5 minutes. Do them back to back and write down the numbers. You'll need them.
This tells you if you're actually getting the speeds you're paying for. Write down your Download and Upload numbers in Mbps.
Run Speedtest →This checks whether your connection degrades under load — the hidden problem most ISPs ignore. Write down your Grade (A through F) and the Download Active latency number.
Run Waveform Test → What do the grades mean?The grade tells you how badly your connection degrades when it's being used. This is the number that matters most for calls and video meetings.
| Grade | What it means | Real world impact |
|---|---|---|
| A | Excellent — minimal latency under load | Calls and video meetings work perfectly |
| B | Good — some latency increase under load | Mostly fine, occasional hiccups in meetings |
| C | Poor — noticeable latency degradation | Audio calls choppy, video meetings unstable |
| D | Bad — severe latency under load | Calls drop, gaming impossible, meetings fail |
| F | Broken — connection unusable under any load | Nothing works reliably |
Enter what the tests showed you and we'll tell you exactly what it means and what to do next.
If your ISP won't fix the problem, here's exactly what to do — in order.
Run the Waveform test at least 3 times — once in the morning, once in the afternoon, once in the evening. Screenshot each result. The evening one is usually the worst and most important.
Don't say "my internet is slow." Say: "My Waveform bufferbloat test is showing a grade [X] with [+Xms] latency increase during download. This is affecting my video calls and work." They can't argue with a specific number.
If your ISP isn't fixing it, file with the FCC. It takes 10 minutes and puts your complaint on official record. ISPs are required to respond.
File FCC Complaint →Every state has a public utilities commission that regulates ISPs. Search "[your state] public utilities commission complaint" or find yours below.
Find Your State Commission →File a second FCC supplement referencing your original complaint number. Contact your state AG consumer protection office. Find neighbors on the same node experiencing the same issue — a pattern of complaints carries far more weight than one individual.
Find Your State Attorney General →
