Orbi RBR50 Device Limit

Aspirant

Dec 02, 2021

I'll try answer both in same topic.

To test propose I don't have the RBR with DHCP Server, I create on VM with OPNSense only to do DHCP Server with router DNS

So my DHCP Range is from 192.168.1.100 to 192.168.1.254 so I have 154 DHCP lease IP (It's enough because almost my IoT devices have fixed IP)

How I distribued my network?

from 192.168.1.2 to 192.168.1.9 is dedicated to network devices (IPs reserved on DHCP Server by Mac Addrress)

This range are not full like 5 in use

Example:

DNS / Router RBR: 192.168.1.1

DHCP Server: 192.168.1.2

Satellite 1: 192.168.1.3 (RBS 50)

Satellite 2: 192.168.1.4 (RBS 50)

Satellite 3: 192.168.1.5 (RBS 20)

from 192.168.1.10 to 192.168.1.19 is for Virtual Machines with services, like DataBases, HomeAssistant, etc. This range are not full like 7 in use.

from 192.168.1.20 to 192.168.1.40 is for IoT, Smart Switches. This range are not full like 15 in use.

On DHCP Range I have, printer, laptops, android phones, tablets, boxes, Wifi AC controler, TV Service Provider Box, SmartTV.

Right now I have 50 devices connected (based on Router Stats) and I can't get my laptop working, only with fixed IP, that whapens with or without the DHCP Server on Router, please see the attached image.

==EDIT==

Yesterday 30/11/2021 I performed the factory reset in all 4 devices, Router and the Satelits and the issue presists... I realy don't know what I can do more to solve or to figure out what is happen here.

Thank you

The OPNSense user manual says here https://docs.opnsense.org/manual/dhcp.html that there is a DHCP log file. Does the log show the laptop asking for an IP address?

I often set up Wireshark to capture network traffic so that I can examine DHCP packets (requests, offers, ACK's, etc.) Is Wireshark part of the OPNSense package? (I'm a Mint Ubuntu Linux user and have no recent experience with BSD.)

Please follow the DHCP Log

My latop is 60:f2:62:ec:35:9c (TS-LPT-Ubuntu),

I'm Ubuntu user too :D :D but as know the Wireshark is not part of OPNSense but I'll try do something about that tomorrow.

I am also a bit confused about packet flow. The WAN (Yellow) port on the Orbi is the "Port 1" that is connected to the internet modem?
It seems unusual to set up OPNSense and use only the DHCP service. Is this VM also the internet gateway/firewall/etc.?
Like a I mentioned before, the OPNSense is only for test propose, somehow I suspected the Router had some issues with the number of reserved fixed IPs, for that reason I tried the OPNSense. And yes, OPNSense is configured only to be DHCP Server, I dont have the Firewall/Gateway configured there.

Thank you

  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
  
  Discover->Offer
  
  Discover->Offer
  
  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
