ORBI not properly associating static IP
Hello! I've been trying to use the Address Reservation feature under Advanced -> Setup -> LAN Setup. I have a PC that is hardwired (Ethernet, not wireless) to the RBS50 satellite (not the base RB...
I know this is an old thread but I was having the same problem with reserved addresses not getting assigned. I tried the "trick" of changing the DHCP addresses from x.x.x.21 to x.x.x.254 TO x.x.x.21 to x.x.x.100.
Restarted the devices that were not getting the addresses I wanted and it all worked. I had tried restarting the devices prior to changing the auto assigned addresses range and it did not work at that time. Only after changing the range of the auto addresses.
I know enough to know that should not change the addresses I wanted reserved. Nothing was assigned in the >100 range in the first place. All I know is it solved my problem.
Appreciate the ongoing help here! :)
So my MAC address stays the same every time the IP changes:
00-1F-D0-81-9B-07
This is the same MAC address that is always displayed under address reservation in the router's configuration page. Even without address reservation, I've never seen IP addresses change daily or upon every reboot. And to change by +1 each time leads me to believe there is some service or software doing it.
How effing annoying...

There could be some strange mismatch between the PC's DHCP request and the Orbi.
I know what we want to happen. The PC does a DHCP request, the Orbi first looks at the LAN reservation table, finds the IP, checks that it is not in use already, and then offers it to the PC.
This appears not to be what actually happens. I have verified situations where a device *somehow* got an IP that I did not want it to have, and no matter how many times I restarted the device, the Orbi would say, "you already have this one, so keep it." My (tedious) workaround was to turn off the device, configure my laptop with a static IP that matches the bad one, and then when I powered up the device, the Orbi said, "You are asking for an IP that is already in use. Oh, look, the LAN reservation table says I should give you this one that is not in use."
This new wrinkle that seems to be happening to you is the device asks for an IP and the Orbi says, "that one is already taken, but the next one in the DHCP pool is available. Here."
The only way I can see to investigate this is to capture the Orbi LAN traffic (an option on the debug screen) and use Wireshark to look at the DHCP conversations.
I LOVE doing this kind of stuff, and I don't have any work that needs to get done or people hassling me about "Why isn't the internet working."
I would take the easy way out.
- Give the device a static IP (on the device)
- Create a LAN reservation on the Orbi that is outside the DHCP pool
- After this works for a couple of days, experiment with changing the PC back to DHCP
The other alternative is to put the Orbi in AP mode and have the ISP device handle IP assignments. It probably has the same basic structure for assigning IP's to be given out with DHCP. Maybe the PC will "play nice" with the ISP router.
