Is there a socket.io event that activates when the client's internet is slow?

Hello.

I'm in a project on nodejs + socket.io, I'm in big trouble, regarding slow internet client, I need to know if inside socket.io there is some kind of event // If the client's internet is slow it activates this function

socket.event('internetLenta',function(){
  alert('Sua internet está com lentidão, poderá ocorrer delay entre você e o servidor');/
});

Is there a way for me to know if the client's internet is slow via socket.io?
