Okay, so my Orbi will randomly set IP address of 192.168.107.X.. I actually decided to reset my Lan Starting IP Address to 172.16.1.X and its still setting the 192x for certain devices!!!! Im poking my eyes out trying to figure out the issue... any ideas?

Could you please identify specifically which Orbi model this is and the exact firmware release?Would help if you could make a screen shot of the Advanced Tab, Setup, LAN Setup parameters.(mine are attached as an example)

My (limited) experience with the Orbi DHCP process is that it seems to defer much too often to devices which ask to "renew" an existing IP address. "Sure", it says, "go ahead and keep that address." When the correct response (in MY view) is, "Nope. Sorry. My LAN reservation table says you are supposed to use THIS address." For example, sometimes I get a new gizmo and decide, "it's a keeper. I'll assign it an address." Do so, reboot the device and it gets the same damn IP it had before. Are you 100% certain that none of these devices have a "static" IP?

CrimpOn.. thanks for the reply.. its the RBR50 with firmware V2.3.5.30 (should be the latest, per the interface)also see Lan PNG

Thats what i thougth as well.. but no, no hard coded IP.its just really odd and cant figure it out..

Seems pretty clear. Any device which does DHCP "should" get one of these addresses. One trick I have used (sorry, not "trick", I mean "procedure") is to turn off the offending device. Take some other device and set it up with a static IP address matching the one that is "stuck". Then, once the new device is on the network, power up the offending device. THIS TIME, it asks to renew the IP address and gets told, "Absolutely NOT. That is a 'duplicate IP' and you MUST use THIS ONE." I actually have an old cell phone that I use specifically for this.
