I think I found the culprit after similar problem occured using opnsense I tried to remove WAN ipv6 (my provider doesn't have anyway), after about 2 weeks I see that the ipv4 wan get new ip address everytime it's assigned and no internet disconnection occured until now, hopefully it's resolved but I still try to monitor it for another weeks.
Disregard my previous post, the problem still exists. Here's the log after the internet (wan) become idle and I have to restart wan interface :

before this my (private) wan address have different subnet (eg. 10.85.112.96 , last 2 block)
I've just read about hotplug and it seems the event triggered when interfaces down?
Which in this case the interface still up but since the ISP gateway provide new ip address with different subnet nothing ever happened in the log even though the internet is disconnected.
Or perhaps pingcheck is better option? I see OpenWrt has this modules and I try to read about it first although I'm not too comfortable of having to constantly ping every x seconds just to check connectivity.
Doesn't it trigger an ifupdate event?

I suppose but looking at the wan ip address at that time it's still using the old ones (nothing on system log), only after restarting wan interfaces then it changed the wan ip address to new one.
Still I try to look into it, is this command right?
#!/bin/sh
if [ "${ACTION}" == "ifupdate" ] && [ "${DEVICE}" = "eth1" ]
then
ifdown wan
sleep 2
ifup wan
fi
What does this commmand do? I run the script and it adds odhcp6c.user in the etc folder, is there anything that I have to run after that?
ln -s /etc/odhcp6c.user /etc/udhcpc.user

this is recent log from logread (I've cut only last too last few lines because all are similar only different in times), currently the internet is still working for few days (usually after 7 days it begin receiving new ip address)
Here's a workaround for your problem, but it may require some tuning:
cat << "EOF" > /etc/udhcpc.user
logger -t udhcpc "${1} ${ip}/${mask}"
ipaddr_dhcp="$(uci get network.wan.ipaddr_dhcp)"
if [ "${1}" = "bound" -o "${1}" = "renew" ] \
&& [ "${ip}/${mask}" != "${ipaddr_dhcp}" ]
then
sleep 2
killall -SIGUSR1 udhcpc
uci set network.wan.ipaddr_dhcp="${ip}/${mask}"
fi
EOF

thanks, will try. What tuning do I have to set for my setup? I already set sleep to 30s just because it's a bit too often.
I can only guess as I cannot reproduce your issue.
Checking the log should be a good starting point:
logread -e udhcpc
thanks, will wait for few days for any change (I've just upgrade to 19.07.5)

I also noticed system logs getting full with this message since enabling the check, is this related?
edit : now the log doesn't appear again, odhcp and dnsmasq services are disabled though (I use pi-hole in another vm as dhcp and dns server).
This message should be related to virtualization:

The "error" occured again after a weeks and a half, wan and internet connection suddenly off at "Thu Dec 24 00:22:20 2020". How do I check if udhcpc.user runs?
The DHCP client performed a scheduled DHCP renew and obtained the same IP address and mask.
Perhaps you should use another method to detect the issue inside the script.

this is weird, I let the router be without restarting wan interfaces and the next morning when I checked I see the internet already back, about 1 hours since last request renew failed.
You can try using this app:

sorry for late reply, I've already used pingcheck that trigger restart wan interface after failed ping, although not quite ideal in my personal opinion (having to ping every x minutes). Is watchcat similar like these? seems it have advantages of having GUI interfaces than pingcheck.
