- Edit the parameter in the script
NetCard and PingTarget should be modified.
- Add x priority to the script
chmod +x NetReconnector.sh

Add this line which means run the script every 5 minutes between 8:00 and 22:00.

PD: Could be good if you add this script to DietPi because Wifi sometimes drop connection and with this seems to be working 24/7.
I only tested this 2 days and I had no drops, I will write later if my connection drops.
