ISP down, reconnection Polling/script?

[xtropodx]

Is there some setting, script or something otherwise, that can be done to set up a way for router itself to automatically turn the WAN off/on &/or auto reboot if there's an issue with the internet status? ie Turned On, but not connected to ISP or similar?

My internet recently went down for about a day but when it came back up, the router doesn't connect automatically despite the internet working. It's not until I manually turn WAN off & back on again that this typically sorts itself out & with sometimes requiring a modem+router reboot. And I find it's a regular enough issue.

I don't want it to check the connection 24/7 but surely seeing how the router knowns when ISP/WAN is down it could;
-do a auto WAN off->On every x-minutes & if that fails, increasing said Off->On to hourly. Failing that, auto reboot. Rinse & repeat.

Router: RT-AC3200.
Sits behind modem in bridge mode.

Any help would be great thanks!

There are several scripts you can find here on this forum that do what you ask. There is no built in feature to the firmware that does this. If you are going to look at the scripts here, the majority of them rely on pinging google servers / dns and such. A few ping constantly and others only ever so often. I'm sure some of the scripts you will find here will be more efficient than others you may come across, so keep that in mind. But they ultimately do the same thing. I don't think there is a "best possible solution" or "most" efficient one. So give them a try some work differently then others.

Right ok, thanks. If they're on this forum then, what/where am I looking for exactly? This stuff isn't real intuitive or user friendly, especially those still learning, hence request for help. Already have merlin, skynet, & some basic IP blocking script running. Would be nice if this functionality was built automatically into the firmware .

More than likely the problem is on your end. The ISP's use commercial equipment. We can not afford the pro gear so we have to make do with lower grade gear.

I am using this one https://www.snbforums.com/threads/need-a-script-that-auto-reboot-if-internet-is-down.43819/

Put this command in /jffs/scripts/wan-start:

cru a CheckWAN "*/3 * * * * sh /jffs/scripts/ChkWAN.sh wan nowait"

Works like a charm.
