ORBI RBR 50 running 2.3.5.30 I have configured a reserved IP for my Raspberry Pi which is a server, but every reboot, the IP address of the raspberry pi changes the mac address isn't the problem attached image (I've seen some issues with embedded images, so it is also here: <img src="imghost1--grify.repl.co/aborbireserved.png">)

Reserved on the Orbi or on the Pi?

I need to give the raspberry pi a reserved address

One of my Raspberry Pi's was changing MAC addresses on the WiFi adapter every time it rebooted. Turns out there is a "feature" built into one of the Pi networking apps to "randomise" the MAC address. I Googled the heck out of this and eventually found a method to force the Pi to "stop this dammit". (I later decided that loading whatever software package did this was a mistake, so I downloaded a fresh copy of Pi, burned it to an SD Card, and now my Pi no longer randomizes the MAC address..) Assigned IP's on the Orbi are by MAC address. When your Pi has a new IP, does it still have the same IP as before?

Yes, it keeps the same public IP, only the private IP changes. Which raspberry pi and what OS did this occur on in your instance?

I observed this on a Pi 4 after I loaded a complicated home automation package that I later decided, "Who NEEDS this?" and gave up on it.Google searches showed that one of the modules that package loaded was causing the MAC address to change randomly every time the Pi restarted. When I went back to the stock Pi image, that stopped. (The Google searches did turn up methods to prevent it, but I no longer need them.) grify wrote:Yes, it keeps the same public IP, only the private IP changes.I do not understand this. The Orbi assigns only private IP's to devices within the LAN. A Raspberry Pi that is connected to the Orbi should never have a "public IP". What am I not understanding?
