I have been working on cutting the cord , and usually do not use the chromecast that much. But as of late it is my main connection on 2 of my 3 tvs. My main one has a roku. I also have tablo and playon as well. My problem is at times it appears as though my chromecasts are not connected to anything. I get a wifi connection when first starting up the TV and booting up chromecasts. When I go to connect to it with my android phone it says there is no chromecasts around. I tried different TVs, swapping Chromecasts as well as different USB power source. They are connected with the same wifi connection and I know that the chromecasts are connected to the internet because it is cycling though the wallpaper that is downloaded. Any idea why this is happening, it used to work before not sure what is the cause. I did reboot my internet connections and then it started showing up again. But next time it will not show at all. Also having buffering issues with playon playback as well.
