Chromecast with Google TV disabling WiFi on its own

I have 7 Chromecast with Google TVs and each and every one of them continually turns off its WiFi on its own after a period of hours, or days, or whatever of inactivity. It's incredibly frustrating. Yes, I have a dense network with a lot of devices and Google devices in particular....and I have had to ditch Google Nest Wifi because it kept crashing on my network. I now have a TP-Link Deco X90 mesh router system that has been far more stable.

I have rebooted all the chromecasts, factory reset them all, I've rebooted my network and nothing works. This is a common issue I have read on Reddit and some smattering of archived threads here.

 

Please tell me that Google knows about this issue and is attempting to fix it??

At this point, I would suspect some interferences causing the issue.

Try accessing the router mainframe settings and adjust the bandwidth channels.

Well, before you lock it up, I'll just say that I've reconfigured my network and put all of my IoT things on a guest network (separate SSID from main network) that is locked to 2.4 GHz only. I then left all my data hungry items that have 5 GHz support like chromecasts and nest speakers on the main network (broadcasting 5 GHz and 2.4 GHz). This has tremendously helped my network issues. The Chromecasts still disable their WiFi occasionally but it is FAR less frequent than it was. I assume that the network congestion of IoT things was causing part of this, but I believe that the default behavior for the Chromecasts would be to 1) no turn off their WiFi but go into as low of bandwidth priority as they need to still be functional and 2) they should stop broadcasting their WiFi even when connected to a WiFi network. I hope anyone else that finds themselves in a similar situation, can try to declutter their network by adding a SSID or two for low bandwidth devices that just need an internet connection to survive. Hopefully there will be some more optimizations on Google's part to help out in these circumstances.

If you connect all your devices to a single router and the distances between the devices and the router are over 4 metes, I would suggest one or two more routers routers, setup to handle devices per room, and / or connecting the Chromecast devices via ethernet and use the WiFi only when needed.

My Chromecast with Google TV works flawlessly for over a year, without disconnecting from the WiFi network.

It is powered almost all the time and, sometimes, plays for over 72 hours.

Yes, I have a mesh network system and no Chromecast (outside of maybe 1 or 2) is further than 4 m from one of the nodes. It is not possible to connect the Chromecasts with Google TV with ethernet in their locations, WiFi must be used. This was not a problem until about 3-4 weeks ago and now it happens constantly.

I have learned that the major source of interference is the Google devices themselves. Despite being connected to my WiFi network, they (all 7 chromecasts and 20 speakers) broadcast their own WiFi at all times. This multiplies the network interference over and over. You can see this by using a WiFi analyzer app and detecting the networks and interference. There will be a *hidden* network that appears, unplug google devices and that network disappears. This congestion is being caused by poor design of WiFi on Google's part. It should stop broadcasting WiFi once it's been connected to a WiFi. Hopefully Google can fix this issue.

Hey there mmark27,

 

That is a good discovery! If you get the chance, would you be able to re-create the Wi-Fi issue, then submit feedback via the Google Home app with logs enabled so that the engineering team can take a look into this issue? That would help them out immensely! 

 

Thank you for coming back on this issue, I look forward to your response.

 

Best regards,

Jeran

Thanks for giving us your steps to help improve your network connectivity! If you have the chance, I'd recommend that you submit feedback via Google Home letting Google know about your experience, so they can improve the Chromecast's performance.  For now, I'm locking the thread. As always, feel free to make a new thread if you have any more questions or concerns.

Thank you for your help, djtetei!
