G-Code Transfer Issue

I want to connect my linuxcnc pc to local network via ethernet.

I followed this tutorial and succeeded 

Unfortunately when I restart the computer, file no longer works. I am connecting to a Win7 PC. How can I resolve this issue?

I can't be bothered to watch the video, but does it install avahi?

Codes in the video are,

sudo apt update && sudo apt upgrade -y

sudo apt install clfs-utils -y

cd/mnt/
ll

mkdir ShareOnWindows

sudo mkdir ShareOnWindows

sudo mount.cifs //192.168.1.11/WindowsShre/mnt/ShareOnWindows -o user=share
