Guys, Help me please.

Guys, i dont know if im posting this in the right section but please bear with me.

I have a problem guys that my connection is going off and on for just like a couple of seconds but that not all the time. sometimes it occurs for about 4 minutes of using, then stable again after another set of minutes, the connection goes like slowing up to no internet connection and then goes up again in a stable manner and that would is so fast that it would happen for like 2-3 seconds only. As a result, my internet connection for me, goes slower just like streaming videos the buff would stop and run again and playing online games sometimes i experience lag spikes for seconds and then stable again, and also browsing websites sometimes browsing a page would take minutes and then becomes stable again. Sometimes i test cmd > ping google.com -t is i see sometimes request time out then a couple of replies then request timeout again.

Guys i want to ask, do you know a software that could monitor my internet speed and monitor if the internet had been down and then it would just save a note there that for example in this particular time i had no internet connection so i could monitor it and show it to my provider. Or else, you could help me fixing my own problem. Thanks guys so much.
