Network Investigation
Latency is delay. Packet loss is missing data. Jitter is unstable delay.
Many gaming issues are simply called lag, but the network cause can be different. Understanding latency, packet loss and jitter helps identify where the problem starts.
Latency, packet loss and jitter are three different network indicators.
Latency tells you how slow the response is. Packet loss tells you whether data failed to arrive. Jitter tells you whether the delay is stable. When a game feels bad, one ping number is not enough.
Latency is usually measured in milliseconds. It describes how long it takes for your action to reach the server and for the server response to come back.
Higher latency makes the whole game respond more slowly. Skills, shots, movement and server confirmation may all feel delayed.
Packet loss means some packets do not successfully reach their destination.
In games, packet loss can cause rubber-banding, teleporting, missing actions, short freezes or disconnects. Even if average ping looks fine, packet loss can make gameplay feel unstable.
Jitter is unstable latency.
If latency moves from 60ms to 200ms and back again, the game rhythm becomes uneven. Compared with a fixed delay, unstable timing is often harder to adapt to and can affect aim, movement and team fights.
Many games show a simple ping number, but that number does not always describe route quality fully.
For example, a game may show 80ms while packets are occasionally lost or delayed. The opposite can also happen: a stable 150ms connection may feel more playable than a route jumping between 80ms and 250ms.
Start with the local network, then check the route direction.
Compare wired Ethernet and WiFi, check whether the network is shared, look for uploads or downloads in the background, and observe whether the problem appears only at peak hours, on one server, in one region or in one specific game.
Online games do not only need low latency. They need a stable, continuous real-time path with minimal packet loss.
Latency, packet loss and jitter should be read together. Looking only at the lowest ping often hides the real instability that damages gameplay.
