I have tried resetting the box, but it is still not finding my Internet network even though my other devices still are seeing it... What to do?
Here's what has worked for me to re-establish my net connection. I usually have to do this on my most used Roku, a Streaming Stick+, several times a month.
If that doesn't fix it, try disconnecting the power to your Roku for a few seconds. When it comes back up, see if you then can set up the network connection.
