Roku Express, brand new had one before with no problem. It scans for my network with no problem. At first the wireless and internet connection wasn't going through but after a few tries it did. But now it freezes after the checking screen then goes back to scanning options. First error code was 014.50 next one was 014. I'm giving this until tomorrow before I get Chromcast.
This has always worked for me when I've had wifi connection problems:
Restart your router (even if other devices have no problem finding and connecting). Sometimes that's all it takes, if not keep going.
Restart the Roku to clear its memory via Settings > System > System restart (for a Roku TV it's Settings > System > Power > System restart). Again sometimes that's all it takes, if not keep going.
Find and connect to your network via Settings> Network > Set up connection
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.
