Find out what's actually slowing your connection down.
Your provider tests as far as the box on the wall. Everything past that — the cable, the Wi-Fi, the room you're sitting in — is yours to work out. That's the part covered here: which tests reveal which problems, how to read them, and how to fix what they find. No tracking, no ads.
It's hands-on, not hand-holding — expect to open a terminal and do a little reading, and to come away understanding what you actually fixed, not just that it works again.
You don't arrive knowing you have a bufferbloat problem. You arrive knowing your calls break up.
Have it diagnosed
Describe the symptom in your own words. It works the fault down one test at a time, gives you the exact commands for your setup, and keeps a visible record of what's been proven and what's been ruled out.
- Reads the output you paste back and tells you what it means
- Commands come ready — nothing to edit or look up
- Shows what's been eliminated, and the evidence that eliminated it
- Will tell you when your network is fine, too
