Model: OC200  
Hardware Version: V2
Firmware Version: 5.14.26.23 Build:2.16.3 Build 20240620 Rel.81038

Hi, I have an Omada network set up:

 

OC200 Controller (5.14.26.23) + ER605 v2.0 (2.2.6) + Multiple EAPs.

The problem is that I can't assign a fixed IP via DHCP.

My range:

 

I want to reserve an IP: 172.26.2.50, but the device always takes an IP from the 3.x range. I have tested the old router with the same device and it assigns it perfectly...

On my old router, the dhcp reservation worked perfectly (same network)

 

Any ideas?

Nah bruh... you gotta setup a VLAN with this subnet 172.26.2.0/24

 

Assign that VLAN to the port of that client.  Then add the DHCP reservation.

Sure? If the range is 172.26.0.0/22 all devices are on same network.. I cant create vlans (switchs, entire network are old and for this moment is not possible).

 

A tried also fixed ip in the same range of dhcp and also not work...

  @conver Settings -> Services -> DHCP Reservation. Add an entry to associated the MAC address of the device and the IP you wish it to have. I do the same on my network for things like printers.
