How to Fix High Ping and Packet Loss in Online Games

What Causes This?

High ping and packet loss usually happen when your connection to the game server is unstable, overloaded, or taking a poor route across the internet. Common causes include weak Wi-Fi, background downloads, VPNs, outdated network drivers, router issues, or other devices on your network using too much bandwidth. In some cases, the problem is outside your home, such as your ISP or the game server itself.

Common Symptoms

• Lag spikes during matches
• Rubberbanding or teleporting players
• Shots, inputs, or actions registering late
• Packet loss warnings in-game
• Stable FPS but gameplay still feels delayed

How to Fix It Manually

1. Switch from Wi-Fi to Ethernet if possible

   • A wired connection is usually the fastest and most stable option for online games.
   • Plug an Ethernet cable from your PC directly into your router or modem.
   • If you must use Wi-Fi, move closer to the router and use the 5 GHz band instead of 2.4 GHz if your router supports it.

2. Close apps using your internet in the background

   • Open Task Manager with Ctrl + Shift + Esc.
   • Click Processes and look for apps like browsers, cloud sync tools, launchers, streaming apps, or download managers.
   • Close anything you do not need while gaming.
   • Then press Windows + I to open Settings > Windows Update and pause updates if a large download is running.

3. Restart your modem and router

   • Unplug both your modem and router from power.
   • Wait 30 seconds.
   • Plug the modem back in first and wait until it fully reconnects.
   • Then plug the router back in and wait another minute or two.
   • This can clear temporary routing or connection issues.

4. Disable VPNs, proxies, and bandwidth-heavy overlays

   • Turn off any VPN before launching your game.
   • On Windows, go to Settings > Network & internet > Proxy and make sure you are not using a proxy unless you need one.
   • Also disable overlays you do not need, such as Discord, GeForce Experience, or other launcher overlays, since they can add background traffic and overhead.

5. Update your network adapter driver

   • Right-click the Start button and choose Device Manager.
   • Expand Network adapters.
   • Right-click your Ethernet or Wi-Fi adapter and select Update driver.
   • Choose Search automatically for drivers.
   • If Windows does not find one, check your PC or motherboard maker’s support page for the latest network driver.

6. Reset your network stack

   • Click Start, type cmd, then right-click Command Prompt and choose Run as administrator.
   • Run these commands one at a time:
     1. ipconfig /flushdns
     2. netsh winsock reset
     3. netsh int ip reset
   • Restart your PC after running them.
   • This can fix corrupted network settings that cause unstable connections.

7. Test your connection and choose the right server

   • Run a speed test and check your ping, not just download speed.
   • If your game lets you choose a region, select the server closest to your location.
   • If packet loss happens only in one game, check that game’s server status page or community reports. The issue may be on the server side, not your PC.
