Test & troubleshoot

Find out what's actually slowing your connection down.

Many speed tests hand you a number wrapped in ads and trackers, then leave you no wiser. We don't run the test — but we will show you which tests reveal which kinds of problems, how to read them, and how to fix what they find, whether it's your provider, your router, or your own home network. 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.

Not sure where to begin? Pick the symptom below that sounds most like yours, and we'll point you at the right guide.

A speed test can say you're fine while calls and games still stutter. The headline download number measures how much data your connection can move under test conditions. Real applications care about more than throughput: they also depend on latency, packet loss and how the connection behaves while it's busy. See the same connection tested two ways →

Where do I start?

Pick the symptom that sounds most like yours.

"My internet is slower than the plan I pay for — on every device, in every room."

→ How to test your speed

"Speed tests look fine, but video calls stutter and games lag when someone's downloading."

→ Test for bufferbloat

"Only one room, one device, or one cable is slow — the rest of the house is fine."

→ Ethernet guide → Wi-Fi guide

These guides cover the common cases, but no two home networks are quite the same — they assume you're willing to look a few things up and adapt them to your own setup. AI assistants can be useful for making sense of your specific numbers — paste in your scan or test output and ask what it means — though it's worth checking any suggested fixes against the documentation for your own hardware or software.
