Backhaul on 2,4 ghz

[Lexkok59]

Since this week my Orbi RBR50 with 2 satellites have a strange thing.

1 satellite has a backhaul of 5 ghz en satellite number 2 just 2,4.

I have this set now almost 4 months and it always works with a backhaul of 5 ghz.

I just rebooted everything en manually sync,

See my picture for my problem, any help is welcome!

This appears to indicate that satellite two is not able to get a good connection with the router at 5G and has changed to 2,4G to get a better connection.  Radio signals are very sensitive to building materials and distances.  Are you positive that "nothing has changed" about the placement of the equipment or anything in between the units?  Sometimes even a small change in position or orientation can make a difference.

Could be radio interference from other WIFI networks to. Check to see what WIFI networks are close to you.

Thnx for your answer, no nothing has changed in all those months.

Ok, thnx, is there a way to change that backhaul channell to a different channel?

30 feet or more 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?

It can't hurt to factory reset the lone satellite that is having the issue.  Re-sync it directly to the router at an initial distance of 10-20 feet and see if that doesn't allow it to connect the backhaul at 5GHz.  Give it 10-30 minutes at the closer position to complete syncing, then move it back to its original location.

I believe you will find that the 2.4G backhaul is on the same channel as the front facing 2.4G signal.

Reason: there is only one set of radio/antenna at 2.4G.

So, changing the 2.4G channel (1-13 in Nederlands) would also change the backhaul to that frequency.

As you have discovered, something must be "desperately wrong" for the satellite to fall back to 2.4G backhaul because (a) 2.4G has lower bandwidth than 5G, and (b) the backhaul is competing with all of the other 2.4G devices for bandwidth.
