Having a problem with live tv shows freezing up on my streem tv app on my android phone. Checked Wi-Fi and it says my signal is excellent. It was also fine today using tv go channels outside of home. This is just happening in home. I switched to cellular data and it also works to watch go-channels with phone data in home. Switch back to in home Wi-Fi and started freezing up again, even though it says my signal is excellent. What else could be causing this?
