Auto internet verification

Hi guys , i'm doing a project of residential automation using blynk.
I noted, when arduino loss the internet connection ,it do not try to connect again. Someone know the code lines that can check the connection periodically??? i'm using ethernet for this.
Sorry by my bad english. Thanks

It's usually not the case that a few, well chosen, "code lines" can software work exactly like you want. Study and understand Blynk technology, here.

Thanks man, i find it
