Script to toggle WAN

[CMc]

In recent weeks I’m having issues with my ISP modem (virgin media SH3) dropping and out and failing to give my ASUS router a DHCP address.
I can fix this by toggling the “Internet Connection” in main page.

Can I put this into a script? I don’t know enough to write the script. I watched the log to see if I could commands sent when I manually cycled, but nothing showed worthwhile.

then I can run this via SSH and could invoke via Siri Shortcuts. Saves family logging in and faffing etc

off
wait 5
on

Any ideas?

Should be possible with the command "service restart_wan". Service commands are mostly undocumented but you can poke around the source here and find them by searching for strcmp/strncmp.

Add wan-event script in /jffs/scripts
and build a script something like....

#!/bin/sh

# variables passed to wan-event
# $1 > Wan Adaptor
# $2 > Wan state
#               init
#               connecting
#               connected
#               disconnected
#               stopped
#               disabled
#               stopping

if [ $2 == "disconnected" ]; then
  service stop_wan
  sleep <number of seconds>
  service start_wan
fi

Have not tested to see if I got all the bugs out, you may be able to issue service restart_wan without having to sleep first.

Without a sleep of about four seconds, the second _wan command would be skipped over as the first it still being run.
I would use service restart_wan as the sole command and see if that fixes the problem.

Thanks all. I’ll give it a go when it next drops
