How to Fix Packet Loss: A Comprehensive Troubleshooting Guide

#troubleshooting#packet loss#network

What is Packet Loss?

Packet loss occurs when data packets travelling across a network fail to reach their destination. In gaming, this manifests as "rubber-banding," where players teleport around, or hits don't register even when you aim correctly.

Common Causes

  • Network Congestion: Too many devices using the same network (e.g., someone streaming 4K while you game).
  • Faulty Hardware: Damaged ethernet cables, old routers, or overheating modems.
  • Wi-Fi Interference: Signals from other devices (microwaves, baby monitors) disrupting your connection.
  • ISP Issues: Problems on your Internet Service Provider's infrastructure.

Step-by-Step Fixes

1. Restart Your Router

The classic "turn it off and on again" works surprisingly often. It clears the router's cache and re-establishes the connection with your ISP.

2. Switch to Ethernet

Wi-Fi is prone to interference and signal drops. A direct cable connection is much more stable and significantly reduces the chance of dropped packets.

3. Check for Background Downloads

Windows updates, Steam game updates, or 4K streaming on other devices can saturate your bandwidth, leading to packet loss. Pause all downloads before gaming.

4. Use a VPN (Sometimes)

If your ISP has bad routing to the game server, a premium gaming VPN might actually reduce packet loss by taking a more direct path, though it might slightly increase ping.
