I had almost no problems with my Chromecast with Google TV for a year or so. Loved it.
Seems like about since the update to Android 12, my wifi connection has rendered it almost literally unusable.
I use Nest Wi-Fi and have tried putting the mesh point 1', 5', 15', and now 25' away... When I look on the Chromecast, it always says the signal is strong, but on the Google home app, it's always weak, and the connection is incredibly slow, to the point I cannot stream anything .
I have factory reset several times, played with seemingly every setting, compared speeds with other nearby devices... I can't figure out what is going on.
Has anybody any idea?
Found a topic on Reddit with a possible solution. 🙄
Maybe worth a shot:
"I just got this issue fixed from the google support agent. He had me factory reset the device (which I had tried before but to no success). The trick was to decline to use the Google Home app to set it up and instead set it up completely using the remote. Since then things have been working reliably!"
I've been seeing some trouble like this in the past week too w/ a Chromecast w/ Google TV. We'd first notice unusual pauses streaming Disney+, would then check WiFi signal strength (with Google Home app, we have an older Google WiFi network) and the Chromecast showed weak connection. Speed test to the device showed it could sustain only about 5Mbps. Other devices were not affected, they and internet itself tested at 300Mbps+ during the same time that 5Mbps was reported for the Chromecast.
After rebooting the Chromecast, streaming worked fine again, device speed test showing about 183Mbps, which is plenty and what is expected. I did not have to resort to factory reset, at least not to have it working well for the rest of the evening.
Then it occurred again the next day, and rebooting worked again.
The first time we also saw white noise in bright scenes I've not seen before - that may have been something specific to the content (I did not go back to check), or bandwidth throttling (although given the noise pattern it doesn't seem likely), but perhaps the symptoms correlate? (Maybe this indicates overheating, hardware failure, or some source of interference strong enough to affect HDMI connection and Wi-Fi?)
@dlogelinDid you try doing setup after factory reset using only the remote as @RXShorty suggested? It seems plausible avoiding Home app during setup might help somehow, esp. if the Home app's used to hold files during setup to work around limited storage space on the Chromecast.
That said, our device is back to "Great connection" / ~180-200Mbps device speed and normal behavior when streaming similar content/same app as when we were seeing the inexplicable "Poor connection" / 5Mbps device speed. And we did no factory reset, just normal reboots. The Android TV OS build is, and has been, STTE.220621.019.A2.9082754 (the mid-October 2022 Android 12 release.)
Hope we're able to find something in common that points to the issue.
Hey there dlogelin,
I'm just checking up again, did you try the steps that RXShorty provided? Also, there was a new firmware update a couple of days ago, resolving a few issues with the previous update. Double-check for any updates to your Chromecast with Google TV, and see if the problem persists.
