WinMTR

Network Diagnostics Made Simple

WinMTR combines ping and traceroute into one powerful tool. Monitor packet loss, latency, and network routes in real-time—no installation required.

Windows XP and newer GPL v2 License Portable (no install)

Ping + Traceroute in One Tool

WinMTR is a free, open-source Windows application that continuously sends packets to a target host, tracking every network hop along the way. Unlike running ping and traceroute separately, WinMTR shows both in real-time, updating live as data flows through your network.

Originally created in 2000 by Vasile Laurentiu Stanimir as a Windows clone of Matt's Traceroute (MTR) for Linux/UNIX, WinMTR has become a trusted diagnostic tool used by network administrators, ISP support teams, and everyday users troubleshooting connectivity issues.

The tool is completely portable—just extract and run. No installation, no admin rights required, no configuration needed.

Everything You Need for Network Diagnostics

Lightweight, powerful, and designed to give you answers fast.

Real-Time Monitoring

Watch network performance live as WinMTR continuously probes your route, updating packet loss and latency statistics every second.

Packet Loss Detection

Instantly identify exactly where data packets are being dropped along your network path, from your router to the destination.

Latency Tracking

See best, worst, and average response times at each hop. Quickly spot which network segment is causing slowdowns.

Export Reports

Copy results to clipboard or export as text/HTML. Share detailed diagnostics with your ISP or support team in one click.

Zero Installation

Fully portable—extract the ZIP and run. No setup wizards, no admin privileges, no registry changes. Works on any Windows PC.

Command-Line Support

Prefer the terminal? WinMTR offers full command-line support for scripting, automation, and advanced diagnostics.

How to Use WinMTR

Up and running in under a minute.

1

Download & Extract

Download the ZIP file, extract it anywhere. Choose the 32-bit or 64-bit version for your system.

2

Run WinMTR.exe

Double-click WinMTR.exe. No installation needed—it launches instantly.

3

Enter Target Host

Type a domain name or IP address (e.g., github.com) and click Start.

4

Analyze Results

Let it run for 1-2 minutes. Export results via Copy or Export buttons to share with support.

Understanding WinMTR Output

What each column tells you about your network.

Hop Number

Each row represents one hop—a router or server between you and the destination. Lower numbers are closer to you; the last hop is your target.

Loss %

Percentage of packets that failed to return from this hop. 0-1% is normal. Consistent >5% loss indicates a problem at that point.

Latency (Avg/Best/Worst)

Round-trip time in milliseconds. Avg is most useful. Large jumps between hops or high Worst values suggest congestion.

Hostname / IP

Shows both IP address and hostname (if resolvable). Helps identify if the problem is your router, ISP, or a third-party network.

Sent / Received

Total packets sent and received at each hop. More packets = more accurate statistics. Run tests for at least 1-2 minutes for reliable data.

Blank Hops

Some hops show "No response" or timeouts. This is normal—many routers are configured to ignore ICMP. Focus on hops that do respond.

Common Issues & Solutions

Quick fixes for typical problems.

Nothing happens when I start a trace

This is usually caused by antivirus or firewall software blocking ICMP packets. Solution: Temporarily disable your firewall/antivirus while testing, or add WinMTR to the allowed applications list.

"Program cannot be executed" error

You're running the 64-bit version on a 32-bit system. Solution: Use the WinMTR.exe from the WinMTR_x32 folder instead.

High packet loss only at the first hop

The first hop is typically your router, which may deprioritize ICMP responses. Solution: Check if loss continues beyond the first 2-3 hops. If later hops show 0% loss, your connection is likely fine.

100% packet loss at all hops

WinMTR cannot reach the target at all. Solution: Verify the hostname/IP is correct. Check your internet connection. Try disabling VPN or firewall. Test with a different target (e.g., 8.8.8.8).

Some hops show "No response" or blank

Many routers are configured to not respond to ICMP requests for security reasons. Solution: This is normal behavior. Focus on the hops that do respond—if the destination hop works, the route is functioning.

Export not working or file won't save

The export location may be read-only or protected. Solution: Try running WinMTR as administrator, or save to a different location like your Desktop or Downloads folder.
