I'm going to take a wild guess that the "ASUS Healing System" periodically checks system health and reboots a Daemon or the whole system if stuff breaks.

That seems to be the way to keep consumer grade routers from requiring the user walk over and reboot them once a week...



What is it with these routers and the need to get rebooted so frequently? Is it just poor firmware?


They’re underpowered devices with almost no RAM, being asked to push traffic for ever faster internet connections. It’s a miracle consumer grade routers as well as they do.


The configuration space of any complex system diverges exponentially with respect to time. This is as true for computers as it is for you. Biologically, you start life with one set of genes and end life as a chimera, full of mutations.

In this particular case, the set of states that the device is in when it boots is relatively small compared to the set of states that device may be in a week later. More generally, all individual complex systems need to be "restarted" periodically, it's just a question of how often.


A lot of times its software errors caused by powerline ingress from poor electrical isolation at the plug. If the wrong bits get flipped from EM interactions, only quick way to fix it is to reboot and reload.


The software is on the same quality level as IoT devices and shitcoin projects

Domestic routers, in particular, are infamous for their web interface and management daemons often calling command line programs through system() to configure the network (and other system management tasks), instead of directly using the APIs these command line programs use. Not only is this inefficient and fragile, it also not rarely leads to being vulnerable to shell injection attacks (if you're lucky, only exploitable by authenticated users of the web interface).


A lot of routers have this healing system built in. I had a netgear at close to the end of life which was two years After I bought it (I think), would reboot every hour. It was ok for the most part until my uncle came from elsewhere and was working remotely on a video call. It drove him bonkers.


Yeah, sounds like a supervisor.
