First Asus router - No watchdog?

[JoSmittyCan]

I just purchased my first Asus router (RT-AX5400). Was running an old DD-WRT router for years (firmware release 2015) but needed an upgrade.

I'm surprised to see there's no "watchdog" feature similar to DD-WRT (https://torguard.net/images/watchdog.png). With this feature, you tell the router to periodically ping a list of IP addresses (e.g. every 5 minutes), and if none of them answers, the router reboots itself.

It helps guarantee that Internet access is always working, such as after recovering from a power outage. With my old setup, after the power has returned, the router would sometimes not succeed in getting a WAN IP from the modem (maybe the router booted faster than the modem?), resulting in no Internet access. The watchdog would make sure to recover with a reboot 5 minutes later. I see Asus has a "Reboot scheduler", but that serves a different purpose.

How do you guys make sure to never lose house Internet when out of home for long period of time? Do you know of another router brand / model that offers that feature?

If you want a totally foolproof way, hook your router, modem, and any other devices up to an old school wall timer and have it power cycle at 3am every day. That way even if your watchdog freezes or fails you still reboot.

Asus has no built in watchdog but there should be scripts out there if you want to do that.

Thanks for pointing that out. I would have prefered something easier, but it seems there's a way to use the "script_usbmount" NVRAM variable to run a "startup" script that's stored on USB. I'll have to look into that.

There's a script already for DD-WRT that does pretty much what I need. I will probably look at for inspiration.

Thanks,

Need a script that auto reboot if internet is down

Hi, I have merlin 380.64 on asus ac68u and sometimes internet goes down while I am away from home and need to reboot the router to be up again. Can someone please help with a simple script that checks for internet connectivity every few minutes and if it’s down, perform a reboot? Thanks in advance.
