Orbi RBR50 Device Limit

Hi Guys, In past I opened the Discussin about lossing my IoT devices on my network https://community.netgear.com/t5/Orbi/IoT-connection-issues/m-p/2137256#M125630 Well, on that discussion...

My LAN Setup has 51 devices configured in it. (I am a bit OCD about wanting to "know where things are.") I just checked, and this instant I have no devices in the DHCP 'pool' at all.

The log file seems to indicate that the DHCP server keeps offering 192.168.1.184 to the ubuntu machine, and it never accepts the offer.

i.e.

Discover->Offer

Back in the first post, I saw "If I use fixed IP (on my laptop for example) I can connect and have internet, but I can't comunicate with other devices, por example NAS server! Btw the NAS Server is connected to another satellite!"

Is this a 'fixed IP' as in a static IP set on the device itself. or is it an IP set up in the reservation table?

Hello,

Sorry my delay answer you and give more infos to try help me find one solution.

I put the wireshark and one draw of my equipments layout (I'm sorry about my rudimentar draw, if you have any any doubts please be my guest to question.

https://drive.google.com/drive/folders/1IOmjFNZrlysAc9xsiP1quwXfb8HPN3HW?usp=sharing

I have done the wireshark capture in one laptop with DCHP and I'm connected to device 1 (check the draw to understand the numbers), I can hadle with all my devices that are in device 1 and device 2, but I can't access to the devices that are in device 4.

I opened a device that I have access to in the browser and pinged and tried to access a device that I do not have access to via RDP.

I think you can check the IPs on capture,
192.168.1.21 with access
192.168.1.186 no access
192.168.1.2 no access

I don't have any equipment connected to satellite 3, this has the objective of intensifying the signal between 1 and 4

I hope it helps.

Thanks

The drawing shows two RBR50 routers. Are they connected, or are they separate systems with separate ISP connections?

The Wireshark capture showed only two DHCP packets. (In the upper left, enter dhcp in the display filter.

  The router you're seeing is the same, one is the project floor and the other the building floors, my apartment, my mom apartment and my office and all the VMs, Homoassistant server, etc are in my office.
  
  ok, but you saw any packet errors to the IPs i gave yo you?
  
  Thank you

    Thanks for the information. Would it be convenient to make a rough pencil drawing of
    
    How all the equipment is connected?
    
    Where the device running Wireshark is connected?
    
    Wireshark has to be in 'promiscuous mode' to capture packets that are intended for other devices. This is often defeated by network switches which 'know' where certain MAC addresses can be found and send packets only to the switch ports that lead to those devices.
    
    Going back to the first post:
    
    "If I use fixed IP (on my laptop for example) I can connect and have internet, but I can't comunicate with other devices, por example NAS server! Btw the NAS Server is connected to another satellite!"
    
    If devices are in the same IP subnet, they should be able to communicate. i.e. 192.168.1.x with a subnet mask of 255.255.255.0.
