How to run a script, depending on internet connection

Add your script to /etc/network/if-up.d/. Name your script without a '.sh' extension.

Also after adding script run chmod +x /etc/network/if-up.d/yourscriptname to give necessary permission.

Make sure the network interface (e.g. wlan0 or eth0) that should trigger your script when turned on is mentioned in the file /etc/network/interfaces.

I will answer this part of the OP question: "I would love to have this mount automatically"

My favorite tool for automounting network shares is autofs: https://help.ubuntu.com/community/Autofs

AutoFS is my tool of choice to mount my NAS - for all my laptops and workstations.

"autofs is a program for automatically mounting directories on an as-needed basis. Auto-mounts are mounted only as they are accessed, and are unmounted after a period of inactivity. Because of this, automounting NFS/Samba shares conserves bandwidth and offers better overall performance compared to static mounts via fstab."
