Poor backhaul status after Config Sync

Hi,

I'm having difficulties with getting a stable backhaul connection using the RBR40 and 1 RBW30 satelite.

The backhaul status almost all the time shows as "Poor", whatever I try for the location for the satelite (read somewhere that the ideal distance between the router and the satelite is between 12 and 18 m), tried everything from 5m to 20m.

I notice that when I change the 2.4G or 5G channel setting of the wifi, the backhaul status changes to "Good" for a short while. Until the "Config Sync" appears, after which it returns to "Poor". The satelite shows a 5G connection.

Seems to me that after the channel change, the router and the satelite shortly use different channels and after the config sync they use the same. Can it be that the cause interference when using the same channel, which weakens the backhaul connection?

I already disabled 20/40Mhz Coexistence, Daisy-Chain Topology and Fast Roaming and enabled Implicit Beamforming (as suggested in another post in the community), but that doesn't improve anything unfortunately.

Also read that splitting the 2.4G and 5G SSID's can improve the connection, anyone any positive experience with that?

Running firmware V2.3.5.32 on the RBR40 and V2.3.5.6 on the RBW30.

Really looking forward to your ideas and suggestions. I'm convinced that it is a reliable system, but there is something "wrong" somewhere.

With kind regards,

Martijn

Hi,

Seems like changing the pre-amble fixed the issue. The backhaul status is GOOD on 5G and the overal wifi experience is a lot better!

Didn't even try the factory reset yet.

Thanks for the tip!

** UPDATE **
Manually updated the firmware to V2.5.1.16 for the RBR40 and V2.5.0.2 for the RBW30.

No change, behaviour is exactly the same :smileysad:

  What is the distance between the router and satellite(s)? 30 feet is recommended in between RBR and RBS to begin with depending upon building materials when wirelessly connected. https://kb.netgear.com/000036466/How-far-should-I-place-my-Orbi-satellite-from-my-Orbi-router
  
  What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
  Any Wifi Neighbors near by? If so, how many?
  
  Try disabling the following and see:
  Armor, Circle, Daisy Chain, Fast Roaming, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Set Short preamble instead of Long preamble modes. Save settings and reboot the router and satellite(s).
  
  Has a factory reset and setup from scratch been performed since last FW update?

    Hi FURRYe38,
    
    Thanks for your response. Saw some of your other posts with some of the same suggestions you mention here. :smileywink:
    
    The house does have walls between the RBR and the RBW, but not much.
    
    We also unplugged the RBW for a while and most devices were able to connect to the RBR, some with less bars and speed, but still connected.
    
    At first used 2.4G channel on auto, tried 1, 6 and 11. No change.
    There are some wifi neighbors, not exactly sure how many (not at the location right now :smileywink: ), but I was able to find a free 2.4G channel before. Also for 5G.
    
    Armor and Circle are disabled?
    
    Can't set the Set 20/40Mhz Coexistence to 40Mhz only, only disable it completely.
    
    Changed the preamble to short just now, will monitor if any change.
    
    Will do a factory reset when at the location in the near future. Is there a way to save settings? Or is restoring settings not recommended.
    
    Can you explain why the backhaul is good for a short while after any of the wifi settings?
