How to Fix High Ping and Packet Loss in Windows 11

The Problem

In a match or on a Teams call everything rubber-bands and voices chop, even though speed tests look fine. High ping and packet loss are about latency and dropped packets between your PC and the server—download speed barely matters. A 1 Gbps line with 8% packet loss is unusable for gaming; a 30 Mbps line with clean routing is not.

Symptoms

  • Characters teleporting or rubber-banding in online games.
  • Robotic or cut-out voices in Discord, Teams, or Zoom.
  • Web pages that stall for a second then load instantly.
  • Ping that sits fine and then spikes to several hundred milliseconds periodically.

Step 1: Measure Before You Change Anything

Guessing wastes hours. Two commands tell you where the problem is.

Open Terminal and run a sustained ping to a nearby server:

ping -t 1.1.1.1

Let it run for two minutes, then press Ctrl + C and read the summary. What you are looking for:

  • Loss above 0% — genuine packet loss.
  • Wildly varying times (20 ms, then 300 ms, then 25 ms) — jitter, which causes the stutter you feel.
  • Consistently high but stable times — a routing or distance issue, not a local fault.

Then test your own router—use the gateway address from ipconfig:

ping -t 192.168.1.1

This is the key test. Loss or spikes to your own router means the problem is inside your home—Wi-Fi, cable, or adapter. A clean router ping with loss further out means the problem is your ISP or the route beyond it, and nothing on the PC will fix it.

For the path itself, run a long trace:

pathping 1.1.1.1

It takes several minutes and shows loss at each hop.

Step 2: Use a Cable

If you game or take calls on Wi-Fi, this is the single largest improvement available. Wi-Fi shares airtime with neighbours, microwaves, and Bluetooth, and produces exactly the intermittent spikes that ruin latency-sensitive traffic.

A Cat5e or Cat6 run to the router eliminates the entire category of problem. If a cable genuinely is not possible, see fix slow Wi-Fi speeds (2.4 GHz vs 5 GHz) and move to 5 GHz, closer to the router, on a channel your neighbours are not using.

Step 3: Stop Background Bandwidth Hogs

A saturated upload link causes latency spikes even when download speed looks fine.

  1. Ctrl + Shift + Esc → Processes → click the Network column to sort.
  2. End or pause: Steam, Epic, and Xbox downloads; OneDrive and Dropbox sync; cloud backup jobs; and Windows Update.
  3. Set Steam to limit downloads during gameplay (Settings → Downloads).
  4. Check other devices too—someone streaming 4K or uploading video on the same connection will do this to you regardless of your PC's settings.

Step 4: Reset the Network Stack

Worth doing once when things have been unreliable for a while. In Terminal (Admin):

ipconfig /flushdns

netsh winsock reset

netsh int ip reset

Restart afterwards. Note that netsh winsock reset clears third-party layered providers, which is usually the point—VPN clients and old security software leave hooks in that stack.

Step 5: Change Your DNS Server

DNS does not affect in-game ping, but it does affect how quickly pages and services start responding, and ISP resolvers are often slow or overloaded.

  1. Press Win + R, type ncpa.cpl, press Enter.
  2. Right-click your active adapter → Properties.
  3. Double-click Internet Protocol Version 4 (TCP/IPv4).
  4. Choose Use the following DNS server addresses:
    • Cloudflare: 1.1.1.1 and 1.0.0.1
    • Google: 8.8.8.8 and 8.8.4.4
    • Quad9 (with malware filtering): 9.9.9.9 and 149.112.112.112
  5. Repeat for IPv6 if you use it, or leave it automatic.

Step 6: Fix the Adapter Itself

  1. Device Manager → Network adapters → your adapter → Properties.
  2. Power Management tab → untick Allow the computer to turn off this device to save power. This is a common cause of periodic drop-outs.
  3. Advanced tab → disable Energy Efficient Ethernet / Green Ethernet if present. It is a well-known source of latency spikes on Realtek adapters.
  4. Install the adapter driver from the motherboard or laptop maker, not Windows Update's generic one.

Step 7: Check for Interference and Cable Faults

  • Replace the Ethernet cable—a damaged or cheap cable causes retransmissions that look exactly like packet loss. Check the adapter is linking at 1 Gbps, not 100 Mbps (ncpa.cpl → double-click the adapter → Speed).
  • Try a different port on the router.
  • Bypass any powerline adapter or unmanaged switch as a test.

Step 8: When It Is the ISP

If the router pings cleanly but hops beyond it lose packets consistently, collect evidence and report it:

  • A pathping output showing loss starting at a specific hop.
  • Times of day when it is worst.
  • Whether it happens on multiple devices.

Reboot the modem once before calling. Persistent loss at the first ISP hop is a line or equipment fault they need to fix—no PC setting compensates for it.

Pro tip: to see exactly which application is consuming bandwidth in real time and to log dropouts automatically, our Network Traffic Monitor & Analyzer tracks per-app traffic and connection stability.

What Not to Do

  • Don't install a "ping booster" or network optimiser. They cannot change routing between your ISP and a game server, and most simply set registry values that Windows already handles.
  • Don't disable Nagle's algorithm based on a forum post. The measurable benefit is negligible on modern connections and it can hurt throughput.
  • Don't use a VPN to fix ping unless a trace proves your ISP's routing is genuinely bad. A VPN adds a hop and usually increases latency.
