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 question is, there is any limit to the connected devices at same time?
If yes, Is there any way to get around this without turning off equipment?
Netgear says that Orbi routers can support a maximum of 250 devices, and Orbi AX routers a maximum of 512 devices:
https://kb.netgear.com/31097/How-many-devices-can-my-Orbi-system-support
And, no. There is no way to get around these limits. They are based on the underlying IP subnetmasks.
Customers regularly report having more than 50 devices on one network. A couple of years ago there was a report of something like 130 devices active at one time. I, myself, have only about 45 devices active on the network (need to buy more toys!)
Perhaps it would be a good idea to sort of start over by describing the information on the Orbi web interface, Advanced Tab, LAN Setup page.
Specifically what are the LAN TCP Setup
- IP Address
- Subnet Mask
and the DHCP
- Starting IP Address
- Ending IP Address
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
Thank you for the detailed information. At first glance, this seems fine.
The Orbi is in router mode, with DHCP server diabled, correct? (not in Access Point mode)
How is the internet modem connected to all this?
Orbi are in router mode, the modem is only to provide me internet from my ISP is configurated as bridge mode, with Ethernet wired cable in port 4 to port 1 of RBR 50.
Since I have the OPNSense active, yes, the DHCP Server on router are disable.

I can't upload the images :D

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.)
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.?

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.

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?
