RBR40 ORBI assigning IP out of range!
ORBI RBR40 is behaving very oddly.
IP Range is set to 192.168.0.x
I lost internet to my wired ethernet PC. But was able to successfully connect same PC via WiFi.
Checked IP Table and found PC (ethernet) address was 169.254.118.245 !!! No wonder no internet via ethernet.
Unfortunately the WiFi connect is unstable and it would drop.
So I rebooted the Orbi and this time it pull a correct 192.168.0.2 for the PC (ethernet) and all is good. Until it drops. I've repeated this multiple times. I changed the ethernet cable too, just in case.
What is going on with the Orbi? Firmware I noted updated last night.
Using Win10, I checked network connections and Ethernet shows "could not identify network" during those down times. Not surprising.
Help?!

Wish I had a solution. 169.254.x.x is one of those "auto addresses" that a computer assigns when DHCP fails to supply an IP address. https://en.wikipedia.org/wiki/Link-local_address
My Windows 10 computer also does this with the ethernet adapter (says "unknown network"). I either use the network "troubleshooter" or use the network control panel to "disable" and then "enable" the ethernet adapter. Tedious.
I am certain there is a setting (somewhere) that makes this problem go away, but have not yet found it. (I just disable/enable and go on.)
Interesting...
This morning I restarted the router and both satelites ...and for the moment everything is operating fine. Let's see if it stays stable.
The PC now has both wired ethernet and wifi turned on... I'll keep an eye out today to see if that ethernet connection bugs out, in which case my suspicion is that something has gone wrong with the Orbi's ethernet outputs.
I rolled back firmware to V2.6.1.36 just in case.
If I catch the Orbi misbehaving (ie, not assigning proper IP addresses to hardwired devices) would you say that it's a firmware or a hardware issue?

Sorry I was not clear. The Orbi did not "assign" that private IP to the ethernet port. The computer made up that IP itself because it did not get an IP from the Orbi. The problem is entirely within the Windows 10 computer. (My Windows 10 laptop started doing that and I am embarassed that thus far I have not resolved the issue.)
If every device but one is working correctly, then there must be a problem with the router? - NOT.

Just to confirm - Is your Orbi in Router mode or Access Point (AP) mode? Your Orbi is responsible for assiging network addresses only if it is in Router mode, otherwise that responsibility is handled by your upstream modem/gateway.
And the next time it occurs, i.e., when all your wired devices lose internet and DHCP-assigned IP addresses but your wireless devices are just fine, try this experiment: On your Windows PC force it to reconnect by putting it in, then out of, Airplane mode. Does it get an IP address now? You'll need to try this experiment without having also connected by wifi.
To confirm, only the Orbi is set up as router. The modem is Arris SBV3202 - it's a telephony modem and does not have any router or wifi function.
Thanks for the recommendation... I understand where you're going with the "put it in and then out of airplane mode"... similarly I tried to disable / enable the ethernet adapter. That failed to properly assign an IP address.
The only success I had bringing the ethernet to proper function was power cycling the Orbi (and eventually the 2 satelites).
The network has been up now for 24 hours. Not sure if its only a co-incidence, but the Orbi has been lying on its front side for the past 24 hours so that I have easy access to the ethernet ports and to power cycle. Haha, do I dare stand it back up? Could be supersition, but could also be a bad solder joint in the i/o card. Maybe tomorrow if all remains good I'll stand it back up and see if the problem reappears.

Is your PC connected directly to one the Orbi router's ethernet ports? Is it connected to a satellite? Is there a switch inbetween? Are your satellites wired or wireless?
These shouldn't make a difference but it seems simplest if we can first reproduce your network IP address problem with just the Orbi router connected to your PC (and factor out any switch, satellite, etc.).
Also, what are your Orbi's DHCP settings and address range? Do you use DHCP for all your devices or do you have some devices configured with static IP address?
For example, I never use static IP addresses and my Orbi's DHCP uses 192.168.1.2 to 192.168.1.200, I have 73 reserved IPs, and there are only 58 devices connected right now. So there are plenty of IP address available for DHCP.
