How To Check For Packet Loss Between Your Router and Computer Connection

Here is a very simple way for people to check to see if they are getting any packet loss when downloading files that are constantly corrupted or just for trouble shooting a network connection. This is by no means the only way, but it’s a good place to start an investigation.

First open up your command prompt by pressing the Windows Key+R.

Then in the dialogue box, type “cmd” (without the quotes) and press ‘OK’

RUN command box
Then type ‘ping 192.168.0.1 -t’ (without the quotes and note the spaces) and hit Return and let it run for a few mins. Change the 192.168.0.1 to whatever your default gateway is (your router address) the one in the example is for a Netgear router. Here is a list of common router addresses. They will consist of 4 sets of numbers separated with a period (.) You don’t have to ping your router address, you could also try pinging Google for example ‘ping google.com -t’

command prompt screen

After about 2-3 mins press CTRL+C to stop the reading and see if you have any packet loss. You should see 0%

getting ping backs

If you are seeing 0% packet loss, then you know that there is no problem between your router and the computer and you need to expand your investigation. If you are seeing some packet loss, then here are a few things to check

  1. Check the cable that connects between your router and your PC, they can degrade over time and need replacing. If you are wireless, make sure that your drivers are up to date.
  2. Is the Firmware on your router up to date? If not, try to install the latest version.
  3. Firmware is OK? Try the same test with another router is possible.
  4. Contact your ISP. Explain the tests you have done and see if they can help on their end.

Hope this helps.

      @disqus_dRu3rbCJQi:disqus If you are getting a ‘time out’ when pinging your own router then there is definitely an issue.

      Double check that the cable between your router and computer is working correctly

      Try connecting the cable to the router via a different port if available
      If possible, run the same test using another computer (testing to see if the PC is at fault)
      Run the test again using both a wired and wireless connection
      Check that the firmware is up to date.
      Last resort, contact your ISP as in most cases they would have supplied the router when you signed up with them.

        I got timed out on first try, but was because used wrong IP address; some of the routers have more than one option in the list provided, so try the others. In my case, I have a Linksys, and choice of last two digits is .0.1 or .1.1; got timed out with .0.1 but was fine with .1.1

        Just a thought, good luck

      Vlad, I accidently replied to Richard…

      here is message again this time to you…

      I got timed out on first try also, but turned out it was because I used wrong IP address; some of the routers have more than one option in the list provided, so if this applies, I suggest you try the others. In my case, I have a Linksys, and choice of last two digits is .0.1 or .1.1; got timed out with .0.1 but was fine with .1.1

      Just a thought, good luck

    My packet loss was zero percent but every few packets, one would take almost a second, image related. Any thoughts?

      It’s been more than a month since your post but what I would recommend in this scenario is a hard reset of your devices that would include your router, pc and modem. After doing this try the test again for 5 minutes with NO internet traffic whatsoever.
