Continueous Router resets

[josecatala]

Hi all,
New to this forum and I am having a big issue with my ZenWifi Router, I purchased the two pack last year. This has been an on going problem and have tried ASUS Support, but they only tell me to fix my control channels etc... I the system general log I continuously get this crashlog error:

How often do you experience crashes like this?

 

[josecatala]

It happens every few hours, everyday. It's total unreliable. I currently only have KASA Plugs and switches on it.

If you filter out lines that do not contain "crashlog", you can get a complete crash log. And if you compare multiple crashlogs, you should be able to find out if they have anything in common.
I also have this problem of routers crashes on their own, albeit less frequently.
All my crashlogs share a common trait: they all mention a process called epad.
