Hello, we have a relatively new Chromecast with Google TV and have been experiencing intermittent issues that seem like connectivity issues. We have successfully watched several movies through different apps (Netflix, Vudu, YouTubeTV), and during some of them we get notifications that pop us that say "No internet connection" and then some time later says "Internet connected" or whatever the reconnection message is. Oddly, most of the time, the movie just keeps on streaming throughout this whole time period. Sometimes, the movie stops, and the screen eventually goes black, and we back out and try to resume. Sometimes this works, sometimes not. Usually, if we exit completely and turn off and turn wifi back on in the Settings, that is enough to reset or re-establish a connection and we can resume. Another manifestation of similar behavior is if we try to watch a series of YouTube videos in the YouTube app, pretty often we get cut off after only one or two few-minute videos. When we go to click on another one, we just get a buffering circle on a black screen. Backing out and clicking on the video again basically never works in this case, and we don't get an error message saying "No internet connection" in these cases. Furthermore, if we go to try to click on a different video or do a new search, that also does not work. Sometimes, even the icons on the left menu (home, library, search, etc are replaced by boxes with x's in them). There is almost never any problem in the middle of a YouTube video, only between videos. Exiting the YouTube app and turning Wi-Fi off and on again in the Settings also typically works to restore functionality. Obviously, having to take these steps is frustrating and shouldn't be necessary. It's not clear how to troubleshoot this (I have already tried rebooting the modem and router and chromecast since the problems began) or what exactly is going wrong. When it works, we like the interface and using the chromecast, we just want it to work consistently!
I have a fiber internet connection and an HD TV, so I think bandwidth should be OK. Quick speed tests say >100 MB/s for both upload and download. My router and modem are about 4 years old. I see google results for network traffic generators, but I've never used one. Is there an easy approach for a beginner that you would suggest? I'm generally technically savvy, but not in the domain of networks.
Thanks for the help here, kiltguy2112!
mikebind, thanks for providing detailed information about your issue and I'm sorry to hear that you're having an issue with your Chromecast with Google TV (HD). To cover all the bases, please plug it in on a different HDMI port on your TV. Also, check for system update on your Chromecast with Google TV (HD). Here's how: go to Settings > System > About > System update.
If the issue persists, perform a factory reset on your device. Here's a guide: How to factory reset your Chromecast.
Let me know how it goes.
I switched the HDMI port and checked for updates (already up to date). I'll see if the problem persists and then try a factory reset (though that's pretty annoying and I suspect unlikely to help since it came from the factory not that long ago and I already factory reset it once (though that was very early on when I had a problem right after initial setup) ).
Changing HDMI ports did not help and no updates were available. What I would really like is a method to diagnose the problem or at least gather data on the problem. Other devices on the wifi network also sometimes drop their connection (up to, at most, a few times a day), though how often seems to vary by device, and none as frequently as the chromecast seems to when using the youtube app. I am willing to upgrade my router if it is the problem; I am even willing to upgrade to a mesh networking system if that is the problem, but I don't want to spend a large amount of money on something which will not actually address the problem.
Thanks for checking in. Our household has had a couple bouts of illness and a power outage, so I haven't had a chance to try the mobile hotspot approach yet. I'll have to be careful about it as well, because our google fi plan has us pay for data which I imagine will run up pretty quickly streaming video to the chromecast.
