ORBI RBS850 Satellite restarts several times a day

Hi,   I'm using a RBK853 kit, upgraded to V3.2.16.6_1.4.4 version for all parts. RBR850 is configured in AP mode, both RBS850 satellites and RBR850 router are in DHCP mode.   One RBS850 satellit...

    Hello

     

    I forgot to post a follow-up.

     

    After redoing the same test with the netgear support, RMA was granted and the faulty RBS was replaced a dozen of days ago.

     

    So far, it works like a charm.

     

    Many thanks to FURRYe38

Hi,

 

Router is my ISP one : Sagem Livebox 3 Pro for Orange France ISP.

 

RBR850 gets its fixed IP from DHCP (mandatory for Livebox DNS activation), same for the 2 satellites.

 

No more than a dozen of Wifi network nearby.

None with more than -70dBm SNR under wifi analyzer when Orbi's one are over -44dBM (I'm in a separate House).

 

Between 2 restarts, wireless / wired connection through the RBS850 is reliable which does not seems to indicate an interference issue.

 

The RBS850 which restarts often has been power-off for more than a days without change in its behavior.

 

The RBR850 and the second RBS850 were not powered-off more than the time they need to restart.

Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.

 

I presume any wiif radios on the ISP modem are turned OFF fully?

    Manually set to Chanel 11 for 2.4GHz. ISP router has wifi disabled.

     

    So far no restart observed on the satellites (it also spent the whole night unplugged).

     

    Let see if this solves my concern.

     

    In the meantime, any clue on how fixing the 2.4GHz channel could have a influence on the unexpected restart of the system?

      Possible nieghboring wifi...

      What is the size of your home? Sq Ft?
      What is the distance between the router and satellite(s)? 30 feet or more is recommended in between RBR and RBS to begin with depending upon building materials when wirelessly connected.

      Try swapping RBS locations to see if problem follows.

       

      Keep an eye on it...

        3 story house for about 1600 Sq Ft.

        - RBS850 on ground floor (roughly 40 feets distance with RBR850 througt concrete)

        - RBR850 on first floor, wired to Livebox router

        - RBS850 on second floor (close to 20 feets distance with RBR850 througt wood floor) <= This is the one restarting autonomously

         

        I was aware of the 30 feets recommendation but I was not convince it could be the cause of reboot of the system.

         

        I will try to find a better location for the second satellite and keep an eye on it.

         

        At least since I fixed the 11 channel instead of letting it automatic, I did not see any reboot.
