Roku update only change now I have to reconnect to internet every time I turn it on
The only change is the latest Roku update. Internet is Bluetooth, close to router, nothing else have changed but after a year of working fine, now I have to check connect every single time I turn it...
Assuming this is a Roku TV and not a Roku device connected to a TV, you might want to try enabling "Fast TV start" under Settings->System->Power. I know it's not an ideal solution, but it should keep the connection from dropping.
