Diagnose Your Network with Ping, Traceroute, and Speedtest

When you have network issues and want to look for where the specific source might be, three tools are useful.

  • Ping: A tool to measure time between one networked device and another.
  • Traceroute: A tool to display the amount of links between one networked device and another.
  • Speedtest: One of the free tools that estimates your actual bandwidth to and from your Internet service provider.

The following sections show how to run these commands in the simplest form possible. While not reliable for detailed diagnosis, these may help highlight potential troubleshooting opportunities.

 

Run a Ping Test

When looking at the results of this test:

  • The healthiest packet loss rates are less than 1.0%.
  • The round trip times will vary based on your computer's location. Normal connectivity will have Minimum and Maximum round trip times within 30ms of the Average round trip time.

 

Windows 7, 8, and 10

Run a Traceroute Test

This is an intermediate-level test that can show the number of hops between your server and the Highfive web servers. Due to the nature of cloud systems, you may see unusual results. Please ask your IT team for support in interpreting the results of this test.

  1. Open a Command Prompt window.
  2. Enter either of the following:
    • tracert start.highfive.com
    • tracert <your meeting domain>.highfive.com -n 100

OS X

  1. Click on the "magnifying glass" in the upper right hand corner of the screen.
  2. Type "Network Utility" and select the result.
  3. Click the "Traceroute" tab.
  4. In the "Enter the network address to trace an internet route to" field, enter either of the following:
    • start.highfive.com
    • <your meeting domain>.highfive.com
  5. Click "Traceroute".

 

Run an Internet Bandwidth Test with Speedtest

This test makes estimates of your internet bandwidth by downloading and uploading sample data from your device to the nearest Speedtest server.

 

Compare the results of this test with the bandwidth estimates with the values listed in our Network and Personal Device Requirements for Highfive article.

 

Windows 7, 8, and 10, or OS X

  1. Go to www.speedtest.net in your internet browser.
  2. Press "Go"

You can also run the test again, and change the Speedtest testing server to a location near Northern Virginia (where our meeting servers are based), by doing the following:

  1. Go to www.speedtest.net in your internet browser.
  2. Click "Change Server".
  3. Enter "Ashburn, VA" in the search field.
  4. Choose any listed server.
