Packet Loss

performanceintermediate
network qualityconnection stabilitydiagnostics

The failure of data packets to reach their destination during transmission. Normal packet loss should be less than 1%; higher values can cause stuttering in video calls and gaming lag.

Examples

Gaming impact

2% packet loss can cause hit registration issues and teleporting enemies

Video streaming

Packet loss causes pixelation, freezing, or audio sync issues

Poor>1%
Severe>2%

Common Misconceptions

  • Small amounts of packet loss (1-2%) can significantly impact real-time applications
  • Packet loss is different from high latency, though both degrade performance

Optimization Tips

Use wired connection instead of Wi-Fi

high impact

Check for damaged cables or loose connections

high impact

Reduce network congestion

medium impact

Update network drivers and firmware

medium impact

User Impact

VoIP calls

Choppy audio, words cutting out

Online gaming

Rubber-banding, delayed actions, disconnections

File transfers

Slower speeds due to retransmission

Troubleshooting

Issue: Wi-Fi packet loss

Solution: Check signal strength, reduce interference

Issue: Consistent packet loss

Solution: Test modem/router, contact ISP

Technical Details

Formula: Packet Loss % = (Packets Sent - Packets Received) / Packets Sent × 100
