How to identify probable disconnections in your home internet service

In my apartment, we have internet connection provided by a local vendor. This is a FTTH connection (Fiber to the Home) which basically run fibre optic cable right into your home and terminates at the modem.

Recently, we’ve been having frequent disconnections and we had to work with the provider to identify the issue and have it fixed. At last count, we had the frequent disconnection fixed but were still having packet drops which resulted in some of the apps to behave incorrect.

Long and short of it, here is how the packet drops were identified and sent to customer support. Hope it will be useful for people in a similar boat.


  • Click Start
  • In the search field (windows 7 and above) or run field (windows xp), type ‘cmd’
  • A command prompt will appear. Here, type the following command.
    • c:\> ping
    • See if you are getting a response.
    • If so, run the following command
    • c:\> ping -t > ping_statistics.log
    • leave it for an hour or a day
  • After the period which you are interested in, hit ^c (ctrl+c) to terminate the collection
  • Open ping_statistics.log and scroll to the end of the file.
  • You’ll see the statistics. The most interesting field is “% dropped”.

If you don’t see response to ‘ping’ in the first case, there is nothing more to be done and it can be reported straight away to your service provider.

Linux or Mac:

The steps are mostly same, except ‘-t’ flag can be omitted in the ‘ping -t > ping_statistics.log’ command.

Hope this helps. Did you find any other way to sort out connectivity issues from your service provider? Please do share it in the comments.
