What script commands are available to stop and restart the WAN connection?

You could try this:

service "restart_wan_if 0"

Seems to work. Thanks!

Is there a watchdog script to ping say google servers every say 30 seconds, if no reply restart WAN? Seem to be having issues losing WAN every now and then, a reboot fixes the issue.

That is similar to what happens here. Every now and then, the cable network has some kind of "event", but the modem stays "up" and my router thinks it is all still connected. The only way to recover is to power cycle the modem, or restart the WAN on the router. So that's what my script does now. It gets invoked from /jffs/scripts/init-start like this:

/jffs/bin/wan_watch.sh &>/dev/null &

#!/bin/bash
sleep 60
count=0
while true ; do
        sleep 15
        if ping -c1 -w1 8.8.8.8 >/dev/null 2>&1 ; then
                count=0                                 
        else
                count=$((count + 1))
                if [ $count -gt 4 ]; then
                        count=0
                        ifconfig eth0 down
                        sleep 1
                        service "restart_wan_if 0"
                fi             
        fi       
done

Many thanks I'll give that ago.

Edited my original post above, with new/improved version of the script. This one doesn't hit google nearly as often as the earlier script.
