Are you nuts!!!
Theres 2 issues with that:
1. my tv is on one side of the house, my router is on the other.
2. It wont accept ANY network connection without internet.
Im NOT running a cable across the house because Roku cant design a normal IP interface.
If the ONLY purpose of the device was to stream "PAID" content streams there would not be other applications available.
ALSO, under YOU TUBE terms of service, You tube DOWNLOADS TO OTHER DEVICES can be mirrored from the YOU TUBE app without an internet connection. If you dont want to support that, then REMOVE YOU TUBE, but I know you cant, because its your NUMBER ONE APP on the Roku System.
Roku should have an interactive dialog: "Roku is unable to reach the internet. Please select an app that allows local streaming (You Tube, Amazon)"
Your logic and argument have NO merit. If you designed the device like ALL other internet devices, which CAN acquire a dhcp address and remain on the network WITHOUT internet it would not be an issue.
i am a corporate network engineer and I manage over 1500 devices (mobile and media) which have NO issue staying on network when our internet goes off line.
THIS IS A BAD DESIGN ISSUE WITH ROKU, not a user error.
RESETTING THE NETWORK IS NOT AN ACTUAL SOLUTION

No - 2 issues with that suggestion:
1) Roku Streaming Sticks have no physical internet ports - only Wifi.
2) Roku devices still currently check for an active internet connection before allowing the App to proceed. So that wouldn't work either even if you have a Roku device with a LAN port.
