Any thoughts?
Ps: i forgot to add that for a successful reconnect I have to unplug both power and HDMI, plug power back in until the LED goes solid white, and then plug HDMI back in. Just cycling power does not work.
trust the status given in the Chromecast app - it has a tendency to be incorrect with respect to Ready to Cast, Needs Setup, etc. Always go by what Chromecast shows you on the TV screen.
Blinking white - Chromecast is not connected to a WiFi access point (this is also the state it goes into when it needs to be set up)
Solid white - Chromecast is connected to a WiFi access point (it may or may not have access to the Internet)
Solid Red - booting, or settings reset triggered (by holding button down)
As for your problem...
The first thing I'd try is using the HDMI Extender - that will reduce the amount of WiFi signal interference/blockage you get from your TV.
Check your router's (advanced) settings for any power-saving features. Some APs reduce signal strength when there's little/no WiFi activity, so it might be dropping the signal enough that Chromecast loses its connection.
Not sure why you have to unplug HDMI - you shouldn't, unless your TV is providing enough (or more than zero) power on the HDMI port to keep Chromecast alive or semi-alive. Does it show any light or attempt to light when you plug it into HDMI but don't have the power connected?
