Ping test
Ping test
A ping test measures the one number broadband adverts never shout about: latency, the time in milliseconds for a packet to reach a server and come back. The test above sends that round trip and times it. It is what decides whether a game or a video call feels sharp or laggy, and it has almost nothing to do with the download speed on your bill. Here is how to read what it gives you.
Lower is better and the scale is short. Under 20 ms is excellent, 20 to 50 ms is good and what most full-fibre lines deliver, 50 to 100 ms is workable but you start to feel it and anything over 100 ms shows as visible lag between your hand and the screen. Two other figures sit alongside it. Jitter is the wobble between readings, and a steady 30 ms beats a 20 ms that keeps spiking, because it is the spikes that drop your call or your shot. Packet loss should read zero; anything above means data is going missing and arriving late, which feels worse than a simply slow connection.
A game or a video call sends tiny packets back and forth and barely touches your bandwidth, so a gigabit line with high ping still plays badly while a modest full-fibre line with low ping feels crisp. What sets your ping is the kind of line you have and how you are connected to it, not the speed tier you pay for. Full fibre has the lowest latency of any home connection, because light through glass is about as fast as a signal gets and it does not sag at peak the way older part-copper lines do. Distance to the server matters too, which is why a UK game server pings far lower than one across an ocean, and that part is outside your control.
Wire in first, because it is the biggest single lever. An ethernet cable from your console or PC to the router strips 10 to 30 ms off your ping and removes the jitter wifi adds, which is why every serious player is plugged in. Then clear the line during a session by pausing big downloads and getting other devices off the heavy stuff. If you cannot run a cable, get as close to the router as you can and use the 5GHz band. If the ping is still high on a wired connection, the line itself is the ceiling, and no setting changes that. The lift is glass to the door, and the test above shows which full-fibre lines reach you, with YouFibre the one to watch on latency. For the deeper numbers, read what a good ping is.
