Xibo + 4G router

Hi All
I m Guillaume from France
I ve installed Xibo in an outdoor player and i ve integrated a 4G router to update contents
Xibo works very well but I have problem with lost connexion, I mean that it works 2 or 8 hours and after I don’t see my player on the server. In fact I understood that if there s no access to internet by a browser that the Pc lost the internet connexion
For my part , I m going to create a script to open , refresh a page in an internet browser to avoid lost connexion.
Do you know this problem ? Do you have some advice before I try to create a script
FYI,I made a script to restart windows but connexion is still lost if I don’t open an internet browser "to launch internet and get data through the router"
Thanks
Guillaume
