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 -t’ (without the quotes and note the spaces) and hit Return and let it run for a few mins. Change the 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 -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.

      that means that your ip address for your router is different that that…. usually they are or

    it says time out

      @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.

    So how do i expand my investigation if packet loss is 0 and it still lags?

  • problems

    It says i have 0% packet loss, but since i got my new computer internet is shi t, i’ve updated my drivers, and it also says my maximum trip times in milli-seconds is 1519ms, which i assume from playing video games is really bad… can you help me?

  • Blasi Kuvvetli

    Just a suggestion for all of those who are lost about the timing out. Type in /ipconfig, take a look at your “Default Gateway”. That determines whether you have “.0.1” “.1.1” or even “.213821903.213982103821903829103” in the end.

    Before pinging to the router we need to be sure about the default gateway of router. The gateway will be different according to ISP’s. To view your default gateway type ipconfig in command prompt. Then check your gateway and ping.

  • Luther Blissett

    Where do you put your Ip address after it runs for awhile? It just keeps on running and I cant stop it in time to type in my ip address.
