RBR750 not able to connect new RBS750

[rlborques]

I have a RBR750 router wired directly between a Spectrum modem and a LUXUL switch that feeds to ethernet ports around the house. The home has spray foam insulation in all walls (even internal) and solid wood doors which makes wifi propegate really poorly. I have two RBS750 wired to ethernet working as satellites for the system. I still had deadspots in one end of the house so I bought another pair of RBS750 satellites. I cannot for the life of me get these two to work as expected. They appear as attached devices (ethernet is working), they are on the same firmware (V4.6.5.14), they even seem to be acting as a wifi extender (I can see connected devices in the satelitte detail page) they just dont show up as 'satelittes', rather as network extenders.

I am interested in 2 things, thanks in advance for anyone who has ideas/thoughts!

1) Does a RBS750 connect via ethernet, which shows up as a 'generic' netgear wifi extender, have any functional limitations (besides not showing in the newtork topology, and not appearing as a part of the 'updateable' hardware)? AFAICT it is working as a network extension. 

2) Does the RBR750 support more than 2 hardwired satelittes? I have them configured using the setup including an ethernet switch as depicted here https://kb.netgear.com/000051205/What-is-Ethernet-backhaul-and-how-do-I-set-it-up-on-my-Orbi-WiFi-Sy...

Thanks for any suggestions, I have included some images of various configurations/pages for context.

What type CAT# cable are you using? CAT6 is commended. 

You might review this as well. Current released FW has been giving users lots of problems:

What is the brand and model # of the LAN switch your using? 

Connect the RBS ethernet cable to the RBR temporarily, do they connect properly then? 

RBS have to be connected behind the RBR when ethernet connected:

One of two RBS750 described above is presently hard-wired to the RBR750 w/the same result. The switch model is XGS-1024S

The house is wired with CAT5E, the two working satellites are on the same network wired the same way, the only difference between them is that they were setup last week along with the router. Wheras the other two were added this week. I will take a look at that firmware post. I am not opposed to running a manual update on all of them, I am familiar with that process.

You might swap locations with the working RBS to see if problem follows. 

As long as FW version is same on everything, they should work. However could be cabling or switch issues. 

Test each RBS out while in same room with the RBR and good working LAN cable to test them out.

Doing the firmware upgrade seems to have addressed the issue. Thank you for your help @FURRYe38 I really appreciate it.

Awesome. 

Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
