This is the 3rd time this has happened in as many months.
Power drops during a storm, come back on quickly. Cable modem resets, connects to internet (I can test this easily).
Orbi, however, refuses to connect to the internet. Tried power cycling, recycling modem, etc.
This is a repeatable issue as it’s happened exactly the same way multiple times. Finally, after like a day- it starts working!?!
Cable tech came out and theorized somehow the orbi isn’t releasing the the ip addresses assigned when it reboots and I have so many devices - it runs out of address space.
Only reason he thought that was because nothing was working on my network (even the wired stuff), and when he unplugged the pedi from the router- all the other Devices hard wired to my cable modem started working! So the orbi was not only Failing to work- but somehow screwing up all the other devices on the network?
I know it sounds unlikely, but the same issue has repeated itself.
This issue falls into the category "they all do that." You can find threads discussing this on this forum. Even a split-second power glitch would crash my network until I powered off and on my modem, router, and Orbis in specific order and with long wait times in between each Orbi power-on. It has nothing to do with your modem type or your cable service.
All I can suggest is to do what I did and put all your network devices on UPSes. You can find decent UPSes for these low-current-draw devices as cheap as US$40. Having your WiFi continue to work during an outage is a bonus, too.
"when he unplugged the pedi from the router" - what's a pedi?

PS, I forgot to mention that this problem anecdotally is worse when using wired backhaul, which I am. Some users with wireless backhaul report not having this issue. How’s your backhaul set up, lowepg?
I use wired backhaul and have the same issue of my Orbi system (RBR20 + 2 RBS satellites) not having any functionality after a power outage. Unplugging the ethernet cable from both satellites "fixes" the problem and the Orbi system works again (I don't need to power cycle). I then need to reconnect the wired backhaul on each satellite (which sometimes works on the first try and sometimes takes some trial and error).
UPDATE: Lost power briefly last night and I have been unable to get wired backhaul working again. Tried cycling power, synch button etc. with no luck. Especially frustrating because wired backhaul will work for a few minute while LED flashes white, LED then turns amber and Orbi no longer functions, LED then turns solid blue and Orbi no longer functions. As soon as I remove the Ethernet cable, Orbi works properly.
What is the Mfr and model# of the IP modem the Orbi is connected too?
What is the size of your home? Sq Ft? I would do a factory reset on the router and satellite and set up from scratch. Try disabling the following: MIMO, Daisy Chain, Fast Roaming. Save settings and reboot the router and satellite(s). Turn OFF ALL other devices accept for 1 wired PC with the router. Walk thru the setup wizard. Skip adding the satellites during the wizard. After you set up the router and give a new SSID and PW and the router is rebooted. Go in and sync the router and 1 satellite first. You can do this in the same room with the router and satellites. After you get one synced, set an IP address reservation for the 1 satellite. Add, Save and Apply. Then connect the LAN cable to the 1 satellite. Wait 5 minutes. The top LED should turn on BLUE. If so, Turn off the satellite and then the satellite in there remote locations with the Lan cable connected there.
UPDATE: Before trying FURRYe38's procedure I tried simply plugging the ethernet cable back into a satellite that was already wirelessly connected (5G). Pressed the Synch button (not sure that is necessary or not) and wired connected was successfully established in a few seconds. It should be stable until the next power disruption - no idea why the wired connected is sometimes successfully established and other times not. I did not change any settings in between attempts.
