Guides

Each guide answers one question people actually ask — and shows the numbers that settle it. Start with the symptom you have.

Start from the symptom

Six guides, each answering one question. Pick the line that sounds like your problem:

The method behind all of them

Each guide follows the same three steps, because attribution is the whole problem. Measure the near thing first — your own router — so you know whether the rest of the numbers are trustworthy. Then measure the far thing under the condition that breaks it, which usually means under load rather than idle, since a queue only shows when something is filling it. Then compare the two and let the gap name the culprit: a router that stays fast while the internet slows puts the queue outside your flat, and a router that slows with everything else puts it inside. Every number in the guides is one you can reproduce yourself, on a phone, in under a minute.
