How to measure ping and packet loss?

Topic #180 · Updated · Pataisoma.lt

Troubleshooting guide

How to fix the problem

Run ping 1.1.1.1 -n 30 on Windows Command line, ping -c 30 1.1.1.1 on macOS Terminal. Also check your router address and Ethernet instead of Wi-Fi for comparison. Record loss and fluctuations, but be aware that ICMP filtering and busy network can affect the result; ping alone does not show internet speed.

Possible solutions

Choose the method that matches your situation. Start with the simplest suitable option and check the result. If the problem is fixed, you do not need to continue with the other methods.

  1. Local connection ping

    Check your router address and compare Wi-Fi to Ethernet.

    Steps to follow

    1. Click on Start and type "cmd" in the search.
    2. Open the Command Prompt program you found.
    3. Type ipconfig and press Enter.
    4. Write down the Default Gateway in the active connection.
    5. Type ping, a space, that address and -n 30, eg ping 192.168.1.1 -n 30 only if it's your real router.
    6. Wait for the end, record the loss and compare over Ethernet. Mac TCP/IP find Router, use ping -c 30 with your address.

  2. External connection ping

    Compare the test of 30 requests to an external address with a local one; ICMP filtering can skew the result.

    Steps to follow

    1. Click on Start and type "cmd" in the search.
    2. Open the Command Prompt program you found.
    3. Type ping 1.1.1.1 -n 30 and press Enter.
    4. Use ping -c 30 1.1.1.1 in Mac Terminal, not Windows.
    5. Wait for the end and compare the loss and fluctuations with the local router test.
    6. If only the external test is bad, this is not yet proof of failure of one part: ICMP can be filtered.

If the problem persists

First, compare the ping to your router and to the external address. If the connection is bad even up to the router, check the local network; ICMP filtering can distort the result of an external test.
