My Roku 3 arrived yesterday and was eager to hook it up. Unfortunately I experienced the ever annoying error codes 013 and 014 when trying to connect it to the Internet. Browsing all the forums and the best that Google could do did not solve my problem. As a result I ended up calling their support line and they gave me the instructions to access the 'secret' screens.
The problem is related to outdated software on the Roku which restricts it from connecting whether via wireless or wired.
1. Update Software: On your remote please press the house 5 times, press the fast foward 3 times, then press rewind 2 times. You will get a secret screen, There you have to check your IP address that it is not all 0's. Select the option to update software. The Roku player should now restart.
2. Disable Ping: Once that the roku finish the set up, on the remote please press the Home button 5 times, then the Fast Forward (>>) button 1 time, then the Play button 1 time, then the Rewind (<<) button 1 time, then the Play button 1 time, and then hit the Fast Forward (>>) button 1 time.
This will take you to the Platform secret screen. There you have to find the option to disable network ping. Select it and go back to the set up process of the roku player.
That should do it.
Annoying but works.
