this is something new that has never happened before. It connects but doesn't stay connected but my laptop works and is connected with a strong signal. I have not moved the device, it just started to do it.
What Roku device do you have? Go into settings and setup network connection again to see if that helps.
I have restarted the roku numerous times and also keeps connecting but then immediately loses connection when I try to choose and a network to watch
It's Roku+
The model number can be found from your Roku's Home Screen at Settings/System/About.
