Disconnects from what? Try disabling the shortcut forwarding engine.

The router reboots.

If I am watching Netflix or Prime Video, you will not know the router has rebooted, there is no interruption of service.

If I am using nas when the router reboots, every thing shuts down, there is the lost of streaming, including streaming CBS news. Once the router reboots, I can resume streaming CBS news or nas.

If I check the uptime, it is always less than our equal to 1 hour. It reboots every hour on every hour of uptime, like clockwork.

do you have any keep-alives set under administration / keep-alive? or watchdog set under tunnels in your Wireguard setup?

mem-leak...check your free mem and try to find which service is draining it..or you have a bad hardware...may be your cat sleeps over the router and unit heats up Razz

lots of possibilities...
most important is, steps to reproduce the error and serial logs or klogs...otherwise all plain reports are just not making it up... Cool

I have keep-alives set under administration re watchdog but that was set after experiencing the constant rebooting.

As to wireguard, that was set up eons ago and I have not used it in a while. I rely on openvpn.

How to access klogs? I have it enabled.
I have a fan on the router to keep it cool.

if you enable it from GUI then reboot you will see lot more details in the syslog Smile

there are options to fetch those to USB drive/jffs and they will be stored there...never used this option...or you can fetch the log to syslog server on your network or online...papertrail and ect..

but sometimes things could be missing until the syslog comes up that is why serial log is more efficient...

I have achieved success. I have used an older build; entered every thing, basic setup, dhcp server, wifi, 2.4 ghz and 5g, samba, nas and openvpn. It all works. Uptime is over 14 hours. Perseverance.
