The Orbi system (2 sattelites and firmware v2.1.2.18) has recovered after a power outage in the past but did not after a longer than usual outage this week. The house is not occupied so recovery and remote management capability is really important to me as it is very expensive to get people into the house to work on the internet and wifi. I was certain that the internet connection from Xfinity was to blame but when they came out they found the cable modem was working fine and that internet was available to the router. The bottom line is that the tech and my house caretaker reset the Orbi and got me a new remote management address which allowed me to go in and reenter all of my SSID and wifi password information. And yes they tried everything to get the router to reboot properly but it never came back online with wifi that would instantly reconnect with all of the devices waiting for a signal.I would like to know if this is a common problem and what I could do to reduce the possibility of this happening in the future. I am even considering using a switch and a redundant router that I could manage remotely and leave wifi disabled until something like this happens again and then go in and turn on the wifi on the redundant router. For the cost of having people go to the house to reboot or reset the router, I could buy a lot of high quality equipment. Thanks in advance for thoughts and advice.

What is the Mfr and model of the ISP modem? Built in router here by chance?How long was the power out approximately before it came back on.

The cable modem is an Arris Surfboard SB6183. It is just a modem (no router). I chose to bring my own modem and not rent the Xfinity modem/router combo. That has worked fine for the past few years though this is the first off season away with Orbi in charge. Power was out for about 8-10 hours at most.

wow, thats a significant power outage. So what was exactly wrong when the power came back on? No access to the router via the ISP modem? Was Wifi still running or just no internet at all? The Orbi router should come back online if there is a power outage. Something to considier however not sure if it would be of any help since you have this power outage for 8-10 hours, however a UPS back up system might be a good idea. However duration of how long UPS lasts vs what your experiencing may not be helpful.

We are in the Northeast which has had several bad storms this winter. Normally, everything would come back online after an outage. There are over 20 connected devices from cameras to smart plugs and switches so I can easily see that they all reconnected. This time, I didn't see them reconnect so I confirmed that power had been restored and then checked with neighbors to confirm that their internet service had come back. Once I knew it had, I contacted Comcast who said the internet was working and that they could reach my cable modem but I didn't believe that since the Orbi would certainly pick up the signal. I could not reach the Orbi via remote management and a couple of devices that are hardwired into into the Orbi router did not come online either so I feel like the router did not come back online. Comcast came out and confirmed that the internet was working and that it was the Orbi. I am not sure if the wifi on the Orbi was broadcasting the SSID and whether devices were connected since I was not there. But, the tech came to the conclusion that the only choice was to reset the router.

Only thing I can think of which would seem to be a bug in FW, there is a loss of configuration on the WAN port of the router that connects to the ISP modem. It would need to be tested more and I presume your not at the location currently with the router. Only thing I can think of would be to notify NG support DarrenM about this and see if there is anything they can do to help. Seems like an extended pouwer outage or loss of power for some period of time on the Orbi router doesn't work after power comes back on. One would need to pull the power adapter or turn off the power strip that the power adapter is connected to, at sertain timed intervals to see this happens both in short time frames or just longer times when the pouwer is out. I would look into a UPS for both ISP modem and router. I have one, however it only last for about 30 mins.
