How Internet Works

Very few understand how internet works, including techies, so that wrong assumptions are often made when things go wrong.

So tap or click here to find out in less than 5 minutes.

So internet works like the post office.  Like letters, packets are sent and received.   The packets are actually sent one way and sent back to be sure they are perfectly correct.    If not the packets are resent.  

When they are resent too many times without being accepted at the destination, the computer gives up and records a timeout.   This has been a persistent problem here, but at this moment our service here is running very well indeed.

A chain is only as good as its weakest link, and anything can go wrong at any time, so that the internet provider needs to monitor service continuously.   That too often does not happen.   It can be done automatically, however.

The provider can actually check remotely whether your own system is working, and you can check the lights on the router.

Usually the problem is elsewhere and only the provider can fix it by checking all the hardware between your system and the destination of your packets.    Sometimes it is like finding a needle in a haystack and may require high level expertise.
