You can try to access a web page in Ajax every selected period of time. This code will help you:

It is very useful, and because it is Ajax based, is asyncronous, so you can check if the Internet is conected without leaving the original page.
For your convenience try to access a very fast page from a site that is always online (i.e. Google)

Now I am trying to hide it from the website owners because I don't want to get banned. some people are talking about changing some variable names called cdc_ inside of chromdriver and I can't understand how to do it

any method so I can hide the fact that I am using selenium!

How do I check connection type (WiFi/LAN/WWAN) using HTML5/JavaScript?
(4 answers)
Closed 3 years ago.
I would like to know is there any way to check if user is connected from 2G, 3G, 4G, or WiFi using javascript. As of my knowledge only Mozilla provides a Network Information API which helps to detect general connection type like 'wifi', 'cellular' etc.
It is a wrong approach to expose your network to javascript. Anyways for your better understanding please go through the below link
How do I check connection type (WiFi/LAN/WWAN) using HTML5/JavaScript?
And there is one that can be of help but only supports mozilla and for the info you can visit the below link

How to detect online/offline event cross-browser?
(15 answers)
Closed 8 years ago.
I want to know the network status using JavaScript,for example, if I plug out the network cable, there will be a pop up dialog to warn me this thing.
Native JavaScript cannot know the connection status. It depends on the host environment providing the data, which it generally does by asking the operating system's network stack.
In modern browsers, that information will be exposed through navigator.onLine

I know the online status could be checked using the javascript API navigator.onLine.
However, for smartphone html5 apps it would be also interesting HOW the online has been set.
Either by WLAN or using 3G/4G connection.
Is there a way to detect the kind of online connection?
You could use window.navigator.connection but the support for this API is very limited at the moment. Check out: https://developer.mozilla.org/en-US/docs/Web/API/window.navigator.connection
