Google Nest Wifi - Unable to reconnect after power failure

DGU — Sun, 12 Dec 2021 21:27:56 GMT

Google Nest Router is unable to reconnect to the internet after a power failure. This is extremely frustrating and time consuming to fix.

1. Google Nest Wifi router is unable to reconnect by itself to internet after a power failure. Although, to be fair, once when I was on vacations for several weeks, I noticed that Google Nest Wifi router re-connected to the internet by itself after about one week. This is not so great when we have several Nest cameras and we pay for a Nest Aware subscription to record while we are away.

2. I have tried everything I could find to have Google Nest Wifi router reconnect to the internet when I am at home. Switch off everything… Wait… Reconnect internet modem…. Wait… Reconnect Google Nest Wifi router… Wait… It is never able to reconnect. At one point, I even contacted my internet provider to enquire if the problem could be on their side. They confirm that the internet was fine , and I validated by connecting a computer with an ethernet cable directly to the internet modem. The problem is with Google Nest Wifi router…

3. This is extremely frustrating… It take me easily 1 to 2 hours to get Google Nest Wifi router to reconnect to the internet. The only option that works is to factory reset the device (each time the power goes off). And even that is not trivial. Your Google Home App often fails to connect to the devices, display some visual indications that it is “working” only to display a few minutes later that it cannot connect (“Problem connecting”).

In summary:

The Google Nest Wifi router and its two Nest Wifi points work great long as there is power. But after a power failure, it becomes a nightmare, as only a factory reset solves the problem and even that is non-trivial and very time consuming (lots of failure to connect). To me, this looks like a software issue. Don’t you fix issues and provide software updates for your router? I looked around the web and I don’t seem to be the only one experiencing those issues

I seem to be having the same issues. Who can we contact?

We also have this issue, although haven’t left the house for long enough during a power outage to know. But we have the same issue - although it doesn’t always have to be a power outage. If the wifi has a system error or glitch it will cut out and not reset when the wifi router does. Has only happened a couple of times, but we do have to manually reset all the pods to reconnect.

I've got exactly the same issue with Nest Audio and Nest Mini (both gen 2). But I figured what went wrong at least in my case.

After the power outage I noticed that my Nest devices can’t see my 2.4Ghz SSID, but can see 5Ghz one. And every other device can see 2.4Ghz without any difficulties. My neighbors 2.4Ghz was identified by Nest also. And factory resetting devices did not fixed this issue. So it looks like something was changed in my 2.4Ghz setup and broke Nest connection to it.

Looking at router settings did not show me any possible problems at first. But after I looked at WiFi band analyzer app - I saw that my 2.4Ghz SSID was using 12 channel, which my Nest devices (bought in USA) probably can’t use because of regional restrictions (12, 13 and 14 control channels are restricted for USA). But my router (bought in Europe) channel setting was on Auto and it switched to free 12 channel after power outage.

After I selected other relatively free channel below 12 manually - Nest devices reconnected to 2.4Ghz again immediately.
So this particular problem can happen to other routers as well, and it's a good place to check when Nest devices are having connectivity issues. Hope this will help somebody.

Hey, everyone.

Sorry for the connection issues you're having. That sounds like quite a frustrating issue. I just have a few questions, and I know the answers might vary with each of you, that should help us narrow down what's happening.

When it disconnects on the power outage, does it go back into setup mode, or will it simply not connect to the network?
Do you always have to do a full factory reset, or will a power cycle work to reconnect the point?
For those that have more than one WiFi point, is it always the same point that fails to reconnect?
If you perform a network restart via the Home app (not using a power cycle), does it find the point after?
Does the point that fails to reconnect have any status lights showing? If so, what color are they?

If I can get a bit more info from you all, it would help to diagnose things. There have been a few other reports of this, so we're trying to learn as much as possible to come up with a solution. Thanks.

From Canada, on SaskTel’s network.
Two points. Both are having issues reconnecting. It just glows and then if there is no connection Google tells us they’re having an issue and to try again. If the wifi is back on, it might respond but is really slow when it does with a poor connection. Unplugging for a minute or so or restarting the point from the app will resolve the issue until it happens again. Points are within close range (confirmed by Google’s help support) and when working they work excellent. If a device is using our basement connection (where the modem and router are) there are no connectivity issues, unless a power outage, and once a wifi outage. Otherwise, video call streaming has never been affected in the basement. Upstairs with devices connecting to the points will experience issues and loss of connection randomly throughout the day. There usually is no light unless I ask the point to do something, then it glows/blinks white.

The issue on our end is mostly that when the network has a weak connection the points will drop and not reconnect on their own, causing us to manually restart them. It is unknown if the modem is causing the weak connection or the Google Nest router, or both; regardless, both points are affected and fail to reconnect.

power failure is very common where I'm at. I've got about 18 nest devices. Once power comes on, all nodes are not found and are shown to be offline on the google home app. You have to painstakingly watch each node come online over hours. It's not easy to reset each nest device so that it can be found on the network

Every time the power goes out, the router and 2 points blink yellow. The network does appear when this happens, but there is no internet connection. It will only return to functioning properly when I force a factory reset on the router and modem. Resetting on the home app does not do anything.

I always have to do a factory reset of the Nest Wifi router (+ 2 Nest Wifi points) in order to get an internet connection.
The Nest Wifi router indicates having no internet connection (idem for the 2 Nest Wifi Points).
For the status lights, I get all of the colours as I try every possible options: first blinking white, then other colours (blinking).

Hi, everyone.

This is definitely an issue that I need to take to our internal teams for a deeper look. I'll hopefully be able to get more insight from them and I'll update the thread when I know more. Thanks for hanging in there with me on this.

Confirming that I just had the same exact issue after an intentional power cycle. Had an issue with intermittent dropped connection and customer service rep told me to power cycle. Now I get slow blinking yellow on nest wifi router. Modem is fine.

Hi Jeff

every time when we have power outage, it always turn into slow blinking white. The only option is to factory reset and reconnect using set up. Due to this I have to factory reset and connect all other google cameras and reconnect doorbell, thermostat and other google equipment. It’s nightmare each time doing the same work. How do I fix?

I’m jumping on this bandwagon. Same exact issue as described above be other users after an intentional power cycle. I even went through the trouble of getting my ISO to send me a new modem as i blamed it first for such a disconcerting error.
Definitely not impressed with google hardware.

Just happened to me AGAIN. Another 30 minutes of factory resetting equipment ahead of me. And I’m hearing more and more Google Nest users saying they’re experiencing the same issue. This is absurd and should be fixed by now. I tell you what, it would behoove Google to put this at the top of their to-do list before we all jump ship to Amazon or other options. This is outrageous, especially for $300 equipment.

Are you located in Canada? Who's your internet provider?

I'm experiencing these issues as well and I'm strating to suspect that my ISP is to blame. I have a broadband connection in Canada and I called my ISP to get them to reset the DHCP allocation on my modem to rule that out as a root cause, and they would not do it for me!! (Told me it costs them money to renew my DHCP IP...)

What I'm noticing is that if i power cycle either the modem or the nest router immediately after setting it up it works fine and the connection is re-established right away, but if I wait a couple of days and power cycle either the modem or the nest router, I'm unable to get a public IP from the modem!

Wondering if others have thoughts on this.

I’m in SK, Canada and we have SaskTel. I’ve been having the random disconnects and the wifi points don’t reset on their own. I’ve been following this thread for a couple months and it sounds like Google has some bad tech they switched to in August due to the patent court case they lost. Seems to be when the issue started. I think from everyone’s comments it varies on severity probably because of the variety of internet providers. But the issue of the points seems consistent that they drop a connection from the router or modem and don’t want to reconnect automatically - causing wifi to disconnect from devices and not come back without a reset/restart.

Just had this happen to me when I needed to shut off power to replace a faulty outlet in our home:

-Nest Router is in Bridge mode, connected to an Xfinity router.

-When in Google Home, it told me my Nest Router and both Nest Points were factory reset and needed to be removed.

-I then had to spend 90 minutes reinstalling my system, and since it had reconfigured altogether, I had to REINSTALL ALL OTHER GOOGLE DEVICES (every single speaker), re-assign them to groups, and then I spent another 30 minutes REINSTALLING OUR SECURITY SYSTEM.

-This is not only an inconvenience, but a major security issue for homes depending on reliable wifi for their family's security.

The only thing that I can think might help FOR NOW is to go out and buy a battery backup supply, but this is a HUGE issue. Seriously considering switching to a more reliable Mesh network and looking at Amazon home devices.

Any update in the last month? It is February 11, 2022.

Absolutely zero update from Google Nest... It is indeed quite frustrating to spend hours reinitializing everything after each power failure. It also renders a Nest Aware subscription for cameras totally useless if there is a short power interruption while on vacations. Happened to me last summer. No connection for one full week while I was away. I know we cannot go back in time, but I never had such an issue with Apple AirPort Extreme for many many years... I am also looking into purchasing an Uninterrupted Power Supply (UPS) as an unfortunate fix to a a defective and expensive Google (Nest) product.

I am having the exact same issue. Accidentally hit the wrong breaker about a month ago which switched off the router and spent two hours power cycling the modem and routers to get it to work. And then again today, had my power meter replaced and the power went out for literally one second over an hour ago and I still have no internet. Modem is great, router won’t connect. I have spent a lot of money on google nest devices and this is incredibly frustrating.

Same issue here. I have tried pulling the plug on the hubs to reset them with mixed results. Some devices connect, others don’t. On reboot other devices connect, but never do all devices connect. I have found that if I disconnect from wifi and use cellular data to connect to the google nest app, I can reboot (or reset, I forget the exact terminology in the app) the network from inside the app and that seems to fox the issue until the next power outage. Still a pain in the butt for such an expensive product.
