If you're receiving a Device License Error, upgrading your device should help resolve this issue:
- Press 'Menu'
- Press right arrow key
- Press down arrow key three times
- Click on Setup
- Click on Systems
- Scroll down to 'System Update'
Make sure the following information is displayed
"The latest version of the Firmware is already installed. There is no need to update."
If there is an update, install it and your device will restart after the new firmware is applied.
If you're still having issues, then please try a few standard network troubleshooting steps:
* Try connecting directly via an ethernet cable rather than wirelessly (if you have this option on your device), and see if it works better.
* Try rebooting your modem and router and restarting the device.
You should also contact Samsung directly to troubleshoot your specific device and settings:
