Hi @NordicZA - a couple of options jump to mind:

1. Place a while loop in the execution:

#!/bin/bash

while [ 1 ]; do 
  phantomjs reboot-modem.js
  sleep 60
done

This creates an infinitely repeating loop. sleep 60 will sleep for minute.

2. Use a cron job: https://opensource.com/article/17/11/how-use-cron-linux

@jonathanhoskin thank you so much! I managed to do the first one really easily, thanks for your help!

👍 @NordicZA glad you got it sorted

Thanks heaps for this script! Just wanted to add that this also works for the Huawei B525 (specifically, the Optus version used for home broadband in Australia):

Nice one @pantsofpie - good to hear!

Hello, script worked great on my B525 on old software version. Now there is a new update (81.191.13.00.1134) and everything has been redone.
