R9000 is rebooting several times a day without any known reason

Hi all,

 

I do have a problem with my R9000 which is rebooting several times a day without known to me reason.

Checking the log, I can see only the information from the moment it started up then following up the regular info.

Hardware Version R9000

Firmware Version V1.0.5.24

GUI Language Version V1.0.0.400

Operation Mode Router

 

Here is the log:

 

 

 

 

 

 

Can you help me to find out what could be the reason of such strange behavior, please?

 

Kind regards

/me

    try doing a reinstall of the firmware. do it over a hardwired connection. Afterwards, factory reset the router and do a clean reinstall (not from backup). 

    I'd also leave your chromecast off for a period. See how stable the router is after that.

      Hi plemans,

       

      I have followed your advice I after the reset and reload of the firmware I notice about twice less reboots then previously - but it still restarting without any known to me reason.

       

      Seems, it is for change,

       

      Thanks
