6.2-27 update will not find any network

[Posmus]

My nest updated to 6.2-27 today and now it can not find any network. I have restarted and rebooted the thermostat and my modem several times. Nothing.

And here also mine has updated and now no WiFi network found, restart-reboot does nothing to solve this issue. My living has not updated and it’s working fine. What’s fix here?

I'm having the same problem,  Called Google and they are sending a replacement.  It's frustration though.

[Posmus]

Thanks for your reply. Please share the phone number you called to reach the department at Google who can issue a replacement.

[Daleks]

You will have to go through troubleshooting with Google support.  It was determined the battery wasn't charging.   Thermostat is still under warranty.  1-855-469-6378

[Posmus]

Thank you! Will do.

I think I’m having the exact same problem. Software updates at 2am this morning and no it says it’s not getting power. 

[wayneb64]

Not sure when it updated, but mine is at that level and I am stuck on W5 with an RMA coming. Does it kill the WiFi chip or is there no way to update it once it's got this bad version?

[YoSB]

For mine, ends up it wasn’t the software update. My unit had a plugged drain line and when the drain pan hit some water in it the sensor killed power to the system, so the Nest no longer had a power supply.

Mine is now intermittently saying it can't find wifi or giving me error w2. This morning it said it couldn't find the network but then when I went to network settings, my network was the only one it showed at all until it connected.

I got my RMA yesterday and it's up and running fine but its software is at only at 6.2-22, will it eventually load 6.2-27 and cause my new Nest to lose the network again?

I just had similar Wi-Fi connection issue plus also losing connections to my remote nest temperature sensors.

I was able to resolve the issue by resetting my Nest Thermostat to factory default setting. The software version remained at latest 6.2-27. after factory default.

I took the followings steps:

1. Removed the devices from my Nest account. In my case using iOS Nest app.

2. While Nest Thermostat is still plugged in and powered, dial to Settings - Nest App - Reset - Factory Default

3. After reset, using iOS Nest App, follow the steps as if adding a new Nest device.

Note: Unfortunately, this will reset Nest past temperature, it’s e-Learning histories, and need to redo schedule. However, a small inconvenience when comparing to having only a hockey puck on the wall. 

So far, so good for me.

Thank you, I will give it a try and let you know my results.

[wayneb64]

I don't think your situation is a match to mine or the OPs. After factory reset my Nest could also see NO networks even though my phone's WiFi analyzer could see my network plus a handful of my neighbors.

6.22-27 update is absolutely a thermostat killer. Since update, BOTH therms will NOT stay connected to Wi-Fi. The App will not respond and sync to the therms. I spent 4+ hours uninstalling and reinstalling both therms and the software; then spent 4+ hours on 2 calls to ‘customer service’ who can see the issue , only to be told I need to buy new Displays at full price to fix. No way. It’s a software/ firmware issue but Google/Nest won’t acknowledge it. I’m moving on to a better company. 

[Posmus]

Thanks for your reply, Jollygrog. Yes, I will be looking to replace my 2 nests as well, - probably with Ecobee. Google does not take responsible for it's products, at least with Nest.

[DRMM]

Same problem….they say buy a new one…..BS

[Avwunder]

Firmware failures are rampant on these thermostats. Google says to buy a new one after a year and warranty expires. I smell a future class action.

[Posmus]

• Update - Google agreed to replace my broken nest and sent me a new one. After set up, the new nest connected to my network. I have returned the old, damaged nest and hopefully all is good now.

Not sure if the 6.2-27 is at fault but NOW my furnace will NOT shut off or cycle properly!!  But after reading these problems I suspect it has SOMETHING to do with it!  Its a 2017 model and they're suppose to be rated to last TEN years!!

Hello sefore,

I'm sorry for the experience. I understand that it can be frustrating when your device won't work as intended. But I'd love to help and see what's going on.

A few questions: is your thermostat also not detecting any Wi-Fi network? Since when did you experience short cycling on your furnace? Also, does your thermostat have a C-wire?

I'll look forward to your response.

Regards,

Mark
