Ping, Latency & Jitter: The Hidden Quality Metrics

You can have the fastest 1,000 Mbps fiber connection in the world, but if your Ping is high or your Jitter is unstable, your Zoom calls will freeze and your online games will be unplayable. Here is why.

1. Latency: The Speed of Light Problem

Latency is the actual time delay. In networking, we measure "Round Trip Time" (RTT). If you click a link, the request travels to the server, and the server sends data back.

Ping is the utility tool used to measure this. When people say "I have high ping," they mean high latency.

• 0-30ms: Perfect (Gaming, Voice over IP).
• 30-100ms: Good (Web browsing, Streaming).
• 150ms+: Noticeable Lag (Delayed video, gaming "warps").

2. Jitter: The Consistency Metric

Imagine you are playing a game.
Minute 1: Ping is 20ms.
Minute 2: Ping is 20ms.
Minute 3: Ping is 250ms.

That variation is Jitter. High jitter is often worse than high latency because computer programs can't predict when data will arrive. This causes "stuttering" in video and "teleporting" in games.

3. Packet Loss: The Silent Killer

If data is sent but never arrives, that is Packet Loss. This is usually caused by a bad cable, a failing router, or severe network congestion. Even 1% packet loss can make a 1Gbps connection feel like dial-up.

4. How to Fix Poor Ping/Jitter

1. Switch to Ethernet: Wi-Fi is the #1 cause of jitter. Radio waves are inconsistent; cables are not.
2. Remove "Bufferbloat": If someone else on your network is uploading a large file, it fills your router's memory (buffer), causing your ping to spike. Using a router with Quality of Service (QoS) rules can fix this.
3. Change Servers: If you are in New York playing on a server in London, your ping will always be at least 70ms due to the physical distance data must travel through fiber optics.
